Patient monitor power-up tests
NOTE
When the patient monitor is connected to a docking station, use the 
docking station’s power cable instead of the patient monitor’s power 
cable.
1. Remove the batteries and unplug the patient monitor (or the docking 
station) from AC power to turn the patient monitor off.
2. Restore the batteries to the patient monitor and plug the patient 
monitor (or the docking station) into AC power to turn the patient 
monitor on.
3. Verify all of the front panel indicators illuminate on power up.
4. Verify the AC indicator on the patient monitor stays illuminated.
NOTE
If the AC indicator stays on, but the screen is blank, the patient 
monitor is likely in “standby mode” (battery charging). Press the 
POWER button to enter the normal mode.
 If the AC indicator is on, continue with the tests.
 Optional: If either of the CHARGING STATUS indicators is 
yellow, wait for the battery(ies) to fully charge and the indicators 
to illuminate green. The batteries may take up to four hours to 
charge.
 If the battery “fuel gauge” displays the word “ERROR,” the 
battery may be asleep. Refer to “Error messages” on page 6-5.
5. Verify the optional alarm indicator lights both red and amber on 
power up.
6. Verify an audio “beep” sounds at the end of boot up.
7. Test all of the front panel keys and the Trim Knob control. Verify 
that an audio “beep” sounds after each key press.
8. Optional: Check battery power for both batteries.
 Unplug the patient monitor (or the docking station) from AC 
power and open the battery door. Verify one LED in the battery 
compartment is on (batteries must have more than 10% charge). 
 Pull that battery out and verify the other LED lights, thus 
indicating the unit is powered by the other battery. 
 Reinstall battery and plug in patient monitor (or the docking 
station).
