WARNING
PATIENT RISK —Never condition a battery while the monitor is
connected to a patient. Serious injury or death could result.
To condition a battery, use the following procedure.
1. Remove all batteries from the monitor.
2. Insert one battery in slot A.
3. Disconnect the monitor from AC power.
4. Select MORE MENUS > BATTERY STATUS.
5. Allow battery to discharge to less than 90 percent (CHARGE LEVEL).
6. Connect the monitor to AC power and fully charge the battery.
7. Disconnect the monitor from AC power again.
8. Allow the monitor to run on battery power until the "BATTERY LOW" message
displays or until the monitor shuts down.
9. Connect the monitor to AC power again and allow the battery to fully charge.
Store the battery outside of the monitor at a temperature between 20ºC and 25ºC
(68ºF to 77ºF).
When the battery is stored inside a monitor that is powered by an AC power
source, the battery cell temperature increases by 15ºC to 20ºC (27ºF to 36ºF)
above the room's ambient temperature. This reduces the life of the battery.
When the battery is stored inside a monitor that is continuously powered by an
AC power source and is not powered by battery on a regular basis, the life of the
battery may be less than 12 months. GE recommends that you remove the battery
and store it near the monitor until it is needed for transport.
When the battery is stored for a long period of time without being charged, it will
eventually lose all of its charge and "fall asleep." When the battery is "asleep," none
of the LEDs on the battery will illuminate when the battery's Test button is pressed.
You must "wake up" the battery before you can use it again.
The procedure for waking up a battery inside the monitor should only be performed
by qualified service personnel. For more information, refer to the service manual.
To wake up a battery with the external charger (preferred method), use the following
procedure.
NOTE
A deeply discharged battery will require you to repeat the following steps more
than once before the battery will "wake up".
