Eight-bay battery charger functional verification
This procedure helps to confirm the proper operation of the monitor battery charger (008-
0651-XX).
• No battery charger disassembly is required.
• A monitor battery is required.
To verify charger function:
1. Remove any batteries installed in the charger battery wells.
2. Unplug the ac power cord from the rear of the charger.
3. Plug the ac power cord into the rear of the charger and observe the charger top panel.
Confirm the following:
• Each green LED blinks in sequence, and then each yellow LED blinks in
sequence. This confirms proper operation of the LEDs and the charger software.
• The green LED by the ac power symbol (at the far right side of the charger’s top
panel) is on, and that no other LED is on.
4. Insert the battery into a battery well and confirm that the corresponding green LED
begins to flash. (The green LED flashes while charging, and remains on continuously
when the battery is fully charged.) Remove the battery.
5. Repeat Step 4 for each of the other seven battery wells.
Replace fuses in the eight-bay battery charger
If the battery charger ac power cord is connected but the green ac power LED is not on,
the battery charger fuses may need replacement.
To replace the fuses:
1. Disconnect the ac power cord from the rear panel of the battery charger (008-0651-
XX). The fuse module is located directly beneath the ac power receptacle.
2. Use a small flat-blade screwdriver to pry open the black fuse module.
3. Slide out the fuse module, and then unlatch and slide out the fuse holder.
4. Use the screwdriver to dislodge the two fuses.
