NSTALLING THE BATTERIES

Withdraw the battery drawer from the monitor casing, by grasping the side lugs located on

either side of the battery drawer, and, firmly pinching them inwards, simultaneously pull the

drawer outwards. When new, this action can be somewhat stiff and difficult to execute. Care

should be taken not to damage either the drawer or the casing of the monitor when

executing this procedure.

Fresh batteries must be inserted into the four battery recepticles located within the battery

drawer assembly. Care should be taken to ensure that the correct battery polarity is

maintained.

Caution : Improper installation of the batteries may result in heat damage to the

batteries.

Re-insert the battery drawer into the monitor casing, and close.
