Maintenance
Power from the battery is flowing to the printed circuit board (PCB) and
sensors even when the power is off. Therefore, it is very important to
disconnect the battery pack before servicing or replacing sensors or
any components insides the monitor. Severe damage to the PCB may
occur if the battery pack is not disconnected before servicing the unit.
