Battery Maintenance
The battery in the MAC 1200 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 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
After successful self-test, approximately 10 seconds after power-up.
