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.
