Battery Maintenance
The battery in the MAC 1200/1200 ST unit should be exercised regularly.
This means the battery should be allowed to drain between charging
cycles.
If the ECG unit is left connected to wall power and/or only used
sporadically on battery power, a discharge cycle should be performed on
a monthly basis.
Turn the MAC 1200/1200 ST unit on, and allow the battery to drain.
When the Battery Low indicator illuminates, the unit can be connected
to wall power and allowed to recharge.
Use a battery maintenance chart to track the discharge cycles
