  • Page 4: Power Management

    POWER/CHARGE CONDITIONS Power is provided by an internally mounted NI-CAD battery pack, which can be charged by applying a regulated 9V D.C. source to the DC input connector. The 9V source will also provide all the power required by the unit, reverting to battery power when the source is removed The internal battery charger will complete a full charge within 4 hours, the battery management system detects battery and ambient under/over temperature, cell voltage, fast charge time and reverts to trickle charge when limits have been reached.
