4.0 BASIC OPERATION The 5803 Advanced Control Base uses an external AC power source or internal, rechargeable, battery power for operation. It uses AC power when plugged into a proper AC receptacle and the on/off power-switch is in the “on” position. When not plugged in, or AC power is lost, the 5803 Base will automatically switch over to internal battery power. The batteries are automatically recharged whenever the 5803 Base is plugged into an AC power source and the on/off power-switch is in the “on” position. Located next to the on/off power-switch on the head end base (see figure 4) is the power on, fault, and battery status lights. WARNING: When the power cord is removed and/or not plugged into an AC outlet, the protective earth ground stud near the power entry module must be connected to a proper earth ground during use. WARNING: All Locks must be engaged before a patient transfer is performed. 4.1 Casters Each base is equipped with three (3) locking casters and one (1) steer caster. The steer caster functions to allow the table to roll along a straight path when pushed from the head end. The steer caster is located on the right side of the foot end. The steer caster has a green label marked “Steer”. To lock the table base securely in place, it is necessary to engage the lock on each of the four (4) casters. To lock a caster lock, step on the lock tab until you hear an audible click and the tab remains in the down or locked position (see figure 6). To unlock the caster, push the unlock button. When the unlock button is pressed, the tab will click back to the original unlocked position (see figure 7).

4.3 5803 Advanced Base Controls The head end base of the 5803 Advanced Control Base is equipped with four indicator lights (see figure 4). These lights are: 1) on/off AC power switch light, 2) power light, 3) battery status light, and 4) fault light. Under normal AC operation, the on/off AC power switch light and battery status light should be lit green and the fault light should be dark. NOTE: If the fault light on hand pendant or base is lit, the 5803 Advanced Control Base has detected a fault in the system. Determine fault before use (refer to sections 4.2 & 4.3). The head end pivot assembly of the 5803 Advanced Control Base is equipped with three indicator lights. These lights are: 1) 180° rotation lock indicator light, 2) tilt drive status light and 3) rotation safety lock indicator light. Verify that the rotation safety lock switch is in the on position and the 180° rotation lock handle is in the locked position. All three lights must be illuminated before a patient is transferred to the table. These indicator lights are shown in figure 9.

4.3.1 Rotation Safety Lock The rotation safety lock switch locks out the 180° rotation function. This feature is designed to prevent unintended rotation of the table top. When the rotation safety lock switch is illuminated, the table top can still be laterally tilted by pressing the left or right lateral roll button on the hand pendant. The rotation safety lock switch should be turned off only when a 180° rotation is to be performed. If the rotation safety lock switch is not illuminated, press the rocker switch to the on position.
MIZUHOSI 2011

NW0498 Rev F
4.3.2 180° Rotation Lock Indicator When illuminated, the 180° rotation lock indicator light indicates the lock is engaged and the table cannot be rotated 180°. If the 180° rotation lock indicator is not illuminated, turn the rotation lock lever clockwise until the light is illuminated. NOTE: If a 180° patient rotation is to be performed, the rotation lock lever should be rotated counterclockwise approximately one half rotation past the point that the rotation lock indicator light goes out. Rotating the lock lever to this point lessens the drag of the friction control, thereby allowing the table tops to rotate more freely during the rotation. If even less friction is desired, the lock lever may be rotated further counterclockwise, as necessary. If more friction is desired, rotate handle clockwise. After the patient rotation is complete, rotate the rotation lock lever clockwise until the rotation lock indicator light is illuminated.
WARNING: When the rotation lock indicator light is not illuminated, the table top is UNLOCKED regardless of how much the lock lever has been turned clockwise or counterclockwise. Always turn the lock lever until the rotation lock indicator light is illuminated after a 180° rotation. 4.3.3 Tilt Drive Status Indicator The tilt drive status indicator light is illuminated when the powered lateral tilt drive mechanism is in the center position of the +/- 25- lateral tilt range. If the tilt drive status indicator is not illuminated, operate the lateral tilt function using the hand pendant in the appropriate direction until the indicator is illuminated. The head end crossbar should be horizontal when the tilt drive status indicator is illuminated. If the head end crossbar is not horizontal, the internal power tilt mechanism is out of synchronization with the crossbar. Refer to section 4.4 synchronizing the lateral tilt function to reset this function.
MIZUHOSI 2011

NW0498 Rev F
4.4 Synchronizing The Lateral Tilt Function Normally, the head end crossbar and tilt drive mechanism are synchronized so that the tilt drive is in the middle of its travel range when the crossbar is level. It is possible for the crossbar and tilt drive to become unsynchronized if the crossbar is rotated manually. Also, the head end crossbar and foot end crossbar can become unsynchronized (not at the same tilt angle) if a crossbar is rotated manually or the 5803 Advanced Control Base is operated without a table top in place. The crossbars must be synchronized to each other, as well as to the tilt drive mechanism. WARNING: Never attempt to attach a Table Top to the 5803 Advanced Control Base if the head and foot end crossbars are not horizontal and level. Doing so may cause damage to the table top or the tilt drive system. To verify synchronization of the tilt drive and head end crossbar: 1. Confirm that the 180° rotation lock is engaged and Indicator light / switch illuminated. 2. Confirm that the rotation safety lock is engaged and Indicator light / switch illuminated. 3. Use the hand pendant lateral roll buttons to rotate the head end crossbar until it is level. 4. Confirm the tilt drive status indicator light illuminates (on hand pendant or head end pivot assembly) indicating proper synchronization. If the light will not illuminate, the head end crossbar and tilt drive are not synchronized. If the head end crossbar will not level using the hand pendant lateral roll buttons, then the head end crossbar and tilt drive are not synchronized. To re-synchronize the tilt drive and head end crossbar: Different techniques are used depending on whether a table top is attached to the base or not. Choose from the following cases. Case 1: Table top is coupled to the base 1. Confirm table top is attached to H-frame and securely locked in place with the T- pin. No patient or load should be on table top. 2. Turn power switch on. 3. Turn off the rotation safety lock. The switch should not be illuminated. 4. Rotate the 180° rotation lock lever counter-clockwise until it is disengaged. Be careful – this allows the table top to swing freely. 5. The tilt drive mechanism will automatically return to the middle of its range. While this occurs, you will hear the tilt motor running, but the table top will only rotate a little (if at all). 6. When the tilt motor stops, observe the tilt drive status light. If it is illuminated, then the drive is in the middle of its travel range. 7. Verify that the head end and foot end crossbars are level. 8. Turn on the rotation safety lock. The indicator light should illuminate. MIZUHOSI 2011

NW0498 Rev F
9. Rotate the 180° rotation lock handle clockwise until it is engaged (lock indicator light is illuminated). 10. The tilt drive is now synchronized to the crossbars, and the crossbars are synchronized to each other. Case 2: A table top is not coupled to the base 1. Turn power switch on. 2. Turn off the rotation safety lock. The switch should not be illuminated. CAUTION: This allows the foot end crossbar to rotate freely; any load on the crossbar can make it swing. 3. Rotate the 180° rotation lock lever counter-clockwise until it is disengaged. CAUTION: This allows the head end crossbar to rotate freely; any load on the crossbar can make it swing. 4. The tilt drive mechanism will automatically return to the middle of its range. While this occurs, you will hear the tilt motor running, and the head end crossbar may rotate. 5. When the tilt motor stops, observe the tilt drive status light. If it is illuminated, then the tilt drive is in the middle of its travel range. 6. Manually level the head end crossbar. 7. Manually level the foot end crossbar. 8. Turn on the rotation safety lock switch. The switch should illuminate. 9. Rotate the 180° rotation lock lever, clockwise, until it is engaged (lock Indicator light is illuminated). 10. The tilt drive is now synchronized to the crossbars and the crossbars are synchronized to each other.

The following procedure assumes the foot end and head end columns do not have table tops coupled in place. The coupling procedure is as follows: 1. Remove the H-frame from the H-frame storage bracket located on the foot end column. Install the H-frame to the foot end crossbar and secure it with a T-pin. The T-pins are stored in the T-pin quiver located adjacent to each column. The T-pin must extend completely through both sides of the H-frame and the drop lock should be in sight and pivot freely (see figure 11). 2. Remove the H-frame from the H-frame storage bracket located on the head end column. Install the H-frame to head end crossbar and secure with a T-pin. The Tpins are stored in the T-pin quiver located adjacent to each column. The T-pin must extend completely through both sides of the H-frame and the drop lock should be in sight and pivot freely (see figure 11). The head end crossbar is attached to a sliding assembly that adjusts superiorly and inferiorly to accommodate trendelenburg and reverse trendelenburg length compensation. Fully retract the head end H-frame against the head end column. NOTE: If the H-frame is not aligned with the mounting studs, it may bind. Do not force it. Lower the H-frame off and repeat until it mounts easily. Head end

NOTE: Two people are required to complete the following sequence. 3. Select the appropriate mounting hole position on the H-frame to support the table top. Hole selection will differ depending on the table top selected, the patients’ size and the procedure to be performed. Further information on hole selection is available in each of the table top owners manuals. On the foot end, align the table coupling device with the hole in the H-frame and push the T-pin completely through.
MIZUHOSI 2011
18
NW0498 Rev F
WARNING: Verify that the T-pin is inserted through the H-frame, passes completely through the table mounting tube, and through the opposite side of the H-frame and the Tpin drop lock is in sight and pivots freely. 4. To couple the head end of the table top, slide the H-frame and crossbar away from the foot end as necessary to accommodate the length of the table top. Align the holes in the head end H-frame and the table coupling device. Push the T-pin completely through both sides of the H-frame and the coupling device making certain that the drop lock is in sight and pivots freely. The head end and the foot end of the table top are normally coupled at the same hole in the H-frame. The only exception is when extreme trendelenburg is needed. WARNING: Failure to follow the above-prescribed procedures regarding securing the H-frame to the crossbars and T-pin to the H-frame may result in the patient being dropped. WARNING: Prior to rotation, verify that all table coupling devices and H-frames are properly installed and the T-pins pass completely through the H-frames and crossbars with the drop lock in sight and pivots freely. Two (2) T-pins and drop locks should be visible and checked at each end of the table. 4.6 Patient Transfer Turn the power switch to on position. Prior to patient transfer, confirm that the desired table top is secured by the H-frames and T-pins. Refer to specific table top coupling procedure on page 16 of this Owners Manual for detailed information on attaching the table tops. All three indicator lights should now be illuminated. If the tilt drive indicator light is not lit, see synchronizing the lateral tilt function procedure on page 13. WARNING: If all three lights are not illuminated, do not use the base. Verify that the rotation safety lock switch is in the on position and the 180° rotation lock lever is in the locked position. 4.7 Table Top Coupling Procedure With Top In Place When one table top is already coupled to the 5803 Advanced Control Base and you are coupling a second top in order to change tops or facilitate a 180° tabletop rotation, the slide mechanism of the head end sliding assembly will be held in a fixed position due to the fixed length of the first top. This requires a different procedure to couple the second top.
MIZUHOSI 2011
19
NW0498 Rev F
With two people holding the second top, 1. Attach the head end H-frame as described above to the table top at the desired mounting hole. 2. Position the second table top and attach the head end H-frame to the head end crossbar. 3. Attach the foot end H-frame to the foot end crossbar surrounding the table top coupling device. 4. Connect the table top coupling device to the foot end H-frame at the desired mounting hole. Verify that the table top is coupled at the desired height at the head end. 4.8 Patient Rotation The MTS provides the capability of rotating a patient 180° to transfer the patient from the supine to the prone position or vise-versa. This is a manually activated function. The rotation is performed and controlled by the operating room personnel. Refer to the Spinal Table System and Imaging Table Owners Manual, Section 7.0 Rotation Procedures for detailed instruction for a patient rotation. NOTE: At least two people are required to hold and control the rotating motion of the table tops. One additional person should be assigned to monitor the patient’s head during the rotation. 4.9 Rotation Lock System The 5803 Advanced Control Base is designed to engage the rotation safety lock automatically whenever the on/off power switch is turned “OFF”. Automatic rotation safety lock engagement ensures that the table top cannot unintentionally rotate laterally without power. 4.10 Rotation Procedure With an attendant at the head end of the table: 1. Patient is securely strapped to table system. 2. Release the 180° rotation lock by rotating the lever counterclockwise until the 180° rotation lock indicator light goes out. 3. Advise the attendants holding the tabletops that the rotation safety lock is about to be released. 4. Release the rotation safety lock by pressing the rocker switch to the off position. Observe that the indicator light goes out. 5. Rotate the tabletops. NOTE: The attendant performing the rotation must rotate the tabletops 180° toward himself or herself without stopping until the complete 180° rotation is achieved. After the rotation: 1. Immediately engage the rotation safety lock by pressing the rocker switch to the on position and observe that the indicator light is illuminated. 2. Lock the 180° rotation lock by rotating the lever clockwise until the 180° rotation lock indicator light is illuminated. NOTE: The attendant performing the rotation may now release the table tops.
