Battery Operation and Maintenance The Radical-7 Handheld includes a lithium ion rechargeable battery. The Radical-7 Docking Station may include the optional 6.5 amp-hour nickel metal hydride rechargeable battery. Before using the Radical-7 as a Handheld or as a transport monitor, the Handheld rechargeable battery and the optional Docking Station rechargeable battery must be fully charged. To charge the Handheld rechargeable battery and the Docking Station rechargeable battery 1. 2. 3.
Attach the Handheld to the Docking Station. Connect the Docking Station to AC power. Verify that the batteries are charging. •
The Docking Station Battery Charging indicator momentarily flashes and then remains illuminated while the batteries are actively charging.
•
If the internal battery temperature exceeds recommended operating conditions for proper battery charging, the Handheld Battery Charging indicator continuously flashes. When the temperature returns to recommended operating conditions, proper battery charging proceeds.
•
The Handheld battery requires approximately 4 hours for charging. The Docking Station battery requires approximately 6 hours for charging.
•
When both the Handheld Battery Charging indicator and the Docking Station Battery Charging indicator turn off, additional trickle charging may occur to complete charging.
During battery operation of the Radical-7, note that the following operating conditions affect the estimated run time of the included rechargeable batteries:
Estimated Run Times of Battery Power The following tables outline the estimated run times of the battery-powered Radical-7. The time estimates are based on a Radical-7 with fully charged batteries. The time estimates are also based on a Radical-7 with and without the back-light illuminated. The Radical-7 is always configured to include the Handheld battery. It may optionally be configured to include the Docking Station battery. Determine the configuration of the system before referencing the following tables.

Run Time for Handheld Only In this configuration, the Radical-7 is configured to only include the Handheld battery (standard configuration). When running on battery power, it is advisable to operate only the Handheld. On battery power, it is possible to operate the Standalone (Handheld attached to the Docking Station with the Handheld battery providing power to the Docking Station). However, the capacity of the Handheld battery pack is not sufficient to support this mode for long periods of time. For optimal battery run time, configure the device to automatically adjust the brightness. Configuration

1 hour
Replacing the BatteriesBefore installing or removing the battery, make sure the AC power cord is removed and power to the Radical-7 is turned off. To replace the rechargeable Handheld battery 1. 2. 3. 4. 5.
Turn off the Radical-7 Handheld off and remove the patient cable connection. If docked, detach the Handheld from the Docking Station. Loosen the closure screw on the battery compartment door and lift out the battery. Take a new battery and place it in the compartment. Tighten the closure screw. Place the Handheld into Docking Station, turn on line power and charge battery.

Replacing the Fuses Should a power problem blow one or both of the fuses in the power entry module on the rear panel, the fuse(s) will need to be replaced (Fuses are part of Docking Station and not part of the Radical-7). Before starting, the user will need a 5-mm or 3/16-in screwdriver. To replace the fuse(s) 1. 2. 3. 4. 5. 6. 7.
8. 9.
Disconnect device from AC power. Remove AC power cord from the power entry module at the rear of the Docking Station. Using the screwdriver, gently pry loose the fuse cover in the left portion of the power entry module, exposing the fuse holder. Using the screwdriver, gently remove the fuse holder. Note how the fuse(s) are placed in the fuse holder for installation of the new fuse(s). To remove the fuses from the fuse holder, use the edge of the screwdriver blade to pry against the bottom of the metal portion of the fuse where it is secured to the glass portion of the fuse. Place the fuse(s) in the fuse holder, properly orienting the fuse(s). For fuse specifications, see Electrical in Radical-7 operator’s manual. Warning: Fire Hazard: To protect against fire hazard, replace only with fuses of same type, current rating, and voltage rating. Slide the fuse holder back into the power entry module and press firmly to make sure it is completely seated. Close the fuse cover and press gently until it seats completely, flush with the back of the Docking Station.
The device is ready to be reconnected to AC power. If the fuses blow shortly after replacement, the device requires service.

Disconnect any patient cables, sensors, or accessories from the Radical-7. Turn off the Radical-7 and then turn on again. Ensure that there are no audible alarms and that the Audible Alarm feature is not set to silenced. Verify the Nurse Call polarity is set to normal. Connect the common lead of a digital multi-meter to the pin 12 (Nurse Call Common) of the Analog Output connector on the Radical-7. Connect the positive lead of the multi-meter to pin 6 (Nurse Call - Normally Open) of the Analog Output connector and measure that the resistance is greater than 1 MW (open circuit). Trigger an alarm on the monitor (for example, by disconnecting a sensor after it was measuring data). Verify that the resistance is less than 35 ohms.
Analog Output Test To conduct an Analog Output test 1. 2. 3. 4. 5. 6. 7. 8.
Disconnect any patient cables, sensors, or accessories from the Radical-7. Turn off the Radical-7 and then turn on again. Connect the common lead of a digital voltmeter to the pin 2 (Ground) of the analog output connector on the Radical-7. Connect the positive lead of the voltmeter to pin 9 (Analog 1) of the analog output connector. On the device output screen, on the analog 1 option, select 0V Output. See Device Output in Radical-7 Operator’s manual. Verify that the voltmeter measures a voltage of approximately 0V. Change the analog 1 option to 1V Output. Verify that the voltmeter measures a voltage of approximately 1.0V. Repeat steps 5 and 6, with the positive lead of the voltmeter connected to pin 15 (analog 2). See Serial Interface Specifications in Radical-7 Operator’s Manual. Connect a patient cable and sensor and verify that the voltage on pins 9 and 15 are between 0V and 1.0V while measuring a saturation and pulse rate.
Battery Test To conduct a Battery test 1. 2. 3. 4.
Fully charge the Radical-7 by placing the Handheld into the Docking Station and then connect the AC power. Verify that the Handheld Battery Charging indicator is illuminated. When the Radical-7 is fully charged, the Handheld Battery Charging indicator turns off. Turn on the Radical-7 on and verify that the Battery indicator shows a full charge.
