Battery Testing
To test the state of the battery, turn the radio on and press the PRESS TO TALK button. The red lamp
should illuminate. On very low battery, the receiver will carry on working after the transmitter has
grown weak.
Replacement
Although we
strongly
recommend that owners return units to SALCOM for battery replacement, it
is recognised there are cases where it is not practical or convenient. To replace the battery, the
following procedures should be followed:
The middle two case screws may be sealed as an indicator to show that the unit has not been
opened. If this is the case, remove the seal from these two screws. Remove the 6 stainless steel M3
slotted case screws and remove the back cover. Replace the battery with the designated type
(see
Battery Type
below) ensuring the battery connector contacts are both tight.
Perform the battery test detailed above and check for any ingress of water or humidity into the
case. SALCOM recommends the rubber seal be replaced regularly to ensure the unit remains
watertight. Seals are routinely replaced by SALCOM as part of the battery replacement
procedure. Replacement batteries and seals are available from SALCOM (see “SPARES”). The seal
should be eased into the retaining slot taking care not to stretch it, with the join adjacent to the
central fixing point. Replace the rear cover using the original screws, taking care not to trap the
battery wires in the case join. The Battery Change Date label must be updated to reflect the new
shelf life period. If possible, reseal one of the two middle screws.
Battery Type
The SARC radio is designed to run on a nominal 9v PP3 type battery. To realise the shelf life and
operational endurance stated in the specification, the battery must be of the same type as
recommended below. Other types of batteries may be used, but a change in performance may
be experienced. Below gives an indication of performance between a Lithium and Alkaline
battery.
