Passport 12/Passport 8 Operator’s Manual 24-3
24.4 Installing or Replacing a Battery
When the Passport 12 patient monitor uses two battery packs, one battery pack can be easily exchanged while the
monitor operates from the other. If the Passport 12 patient monitor uses one battery pack, you should insert a new
battery pack before the old one depletes.
When the Passport 8 patient monitor is operating on battery power, make sure the monitor is powered off before
replacing a battery.
To install or replace a battery:
1. Open the battery door.

2. Push aside the latch securing the battery and then remove the battery.
3. Place the new battery into the slot.
4. If necessary, replace the other battery following the steps above.
5. Restore the latch to the original position and close the battery door.
24.5 Charging a Battery
To optimize performance, a fully (or nearly fully) discharged battery should be charged as soon as possible. The
battery is charged regardless of whether or not the monitor is currently turned on.
To charge the battery:
1. Install the battery in the monitor.
2. Connect the monitor with the AC power source.
When the battery is charging, the AC power indicator and battery indicator are both on. If the monitor is powered on,
the battery status symbol on the monitor screen displays
when the charging is complete.
