The directions in this chapter generally assume you are facing the front of the cardiograph
as you work. Thus, for example, the “left side of the cardiograph” means “your left side as
you face the front of the unit.”
4The Battery
This section explains how to remove and replace the battery. These procedures apply to all
units.
Removing the Battery
To remove the battery:
1. Turn the cardiograph to Standby.
2. Unplug the cardiograph from AC power.
3. Turn the cardiograph bottom-side up.
4. Slide the battery door in the direction of the arrow until it unlatches (approximately
1/2 inch), as shown in Figure 5-1. Lift off the door.
5. Unplug the battery connector from the cardiograph by squeezing the locking tabs of
the connector and pulling it straight out from the cardiograph.
6. Remove the battery.
To replace the battery, perform the procedure Removing the Battery in reverse.
Dispose of or recycle depleted batteries according to local regulations. Do not
disassemble, puncture, or incinerate the battery assembly.
To insure full battery capacity, connect the cardiograph to AC power and charge the
battery for 16 hours with the cardiograph in Standby mode.
