Instructions To Connect the Battery Charger WARNINGS: • To avoid the risk of electric shock, ALWAYS connect this equipment to a hospital-grade, facility power receptacle with protective earth. • DO NOT modify the power cord. • ALWAYS position the equipment so that the power cord may be easily disconnected as required. • DO NOT place the battery charger within the sterile field. CAUTION: ALWAYS place the power cord where it will not be stepped on, tripped over, or otherwise subjected to damage or stress. 1. Use the power cord to connect the battery charger to a hospital-grade, facility power receptacle (figure 1). The power-up sequence will begin: • A diagnostic test will be performed to ensure the battery charger and each installed charger module is operational • The battery charger software and hardware revision numbers will appear (figures 2 and 3) • The charger module revision number will appear for each installed charger module (figure 4). NOTE: If an ERROR message appears during the power-up sequence, note the error code that appears in the counter area (figure 5). See the Troubleshooting section. 2. If desired, use an Ethernet cable (not supplied) to connect the isolated diagnostics port to a facility Ethernet receptacle. NOTES: • Confirm with a facility IT representative that the Ethernet receptacle has access to the Internet. • See the Network Requirements in the Specifications section. • For more information, contact your Stryker sales representative.

To Charge a Battery Pack CAUTION: When battery packs require postsurgical sterilization, ALWAYS allow the battery packs to cool for one hour before charging. Excess heat buildup from sterilization and charging will damage the battery packs. NOTES: • To ensure maximum operating time, always charge battery packs before sterilization, even if the battery packs have not been used. • The charging sequence may take between 5 and 120 minutes, based on the type of battery pack and the existing level of charge in the battery pack. 1. Install a clean, dry battery pack into a compatible charger module with a NO BATTERY message screen (figure 6). The information screen will momentarily display the battery pack part number (figure 7) and the charging sequence will begin. During the charging sequence, a CHARGING message will appear and the number of illuminated state-of-health bars will increase from left to right (figure 8). After the battery pack is fully charged, a stateof-health test will be performed (figure 9): • Five to eight bars will illuminate in the state-of-health area. More illuminated bars indicates a better ability of the battery pack to store energy. • The counter area will update the charge cycle count (for design integrated components only). • A READY message will appear. NOTE: If the battery pack fails the state-of-health test, a REPLACE message and symbol will appear (figure 10). See the Troubleshooting section.

To Condition a Battery Pack NOTES: • During the conditioning sequence, the battery charger provides a controlled discharge of the battery pack. • Lithium-ion and other specific types of battery packs do not require conditioning. When a battery pack that does not require conditioning is installed in the battery charger, conditioning is not an available option. • Conditioning and recharging may take up to 1.5 hours or longer, based on the type of battery pack and the health of the battery pack. • You may press the END button to interrupt the conditioning sequence at any time. If conditioning is interrupted, the battery charger will automatically enter a charging sequence. 1. From the READY, CHARGING, or REPLACE message screen, press the MORE button. The CONDITION? message screen will appear (figure 11). 2. Press the OK button to initiate battery pack conditioning. A CONDITIONING message will appear and the conditioning sequence will begin. During the conditioning sequence, a CONDITIONING message will appear and the number of illuminated state-of-health bars will decrease from right to left (figure 12). After the battery pack is fully conditioned, the battery charger will automatically enter a charging sequence. NOTE: If a CONDITION ERROR message appears during the conditioning sequence (figure 13), see the Troubleshooting section.

To Access Over Temperature Information NOTES: • Specific types of battery packs allow you to access information about battery pack exposure to over temperature conditions. • The information screen will return to its origin after displaying an over temperature message screen for five seconds. 1. From the READY, CHARGING, REPLACE, or CONDITIONING message screen, press the MORE button. The CONDITION? message screen will appear. NOTE: From the CONDITIONING screen, the # (number) of OVER TEMP screen will appear directly. 2. Press the MORE button again to access the # of OVER TEMP message screen. The counter will display the number of times the battery pack has been exposed to an over temperature condition (figure 14). 3. Press the MORE button again to access the TIME OVER TEMP message screen. The counter will display how much time, in minutes, the battery pack has been exposed to over temperature conditions (figure 15).

NOTE 1: At 80 MHz and 800MHz the higher frequency range applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Universal Battery Charger (REF 7110-120-000) is used exceeds the applicable RF compliance level above, the Universal Battery Charger (REF 7110-120-000) should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating Universal Battery Charger (REF 7110-120-000). b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m. a

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer. NOTE 1: At 80 MHz and 800MHz, the separation distance for the higher frequency range applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
