Recharging a Fully Discharged Battery
If the electrocardiograph does not turn on when unplugged, the battery may be fully
discharged.
To Recharge the Battery
1. Plug the electrocardiograph into AC power.
2. Verify that the green LED on the keyboard lights up. (See Figure 17 on page 22.)
If the LED does not light up, go to “Replacing the AC Fuses” on page 64.
3. Keep the electrocardiograph plugged in for 12 hours.
The first time you turn the electrocardiograph on after a full battery discharge, you are
prompted to reenter the date and time.
If the electrocardiograph still does not turn on when it is unplugged from AC power, you
may need to replace the battery or battery fuse. See
“Replacing the Battery” on page 61
or “Replacing the Battery (DC) Fuse” on page 63.
Note Regardless of the battery condition, you can use the electrocardiograph
whenever it is plugged in.
