Do not allow a battery to remain discharged for long periods of time. While
in storage or long periods of non-use, charge the battery at least every 60-90
days. Failure to maintain a charge on the battery will result in a failure to
take and maintain a charge.
Ensure that the RCS-20US is operated in a dry area and connected to
a GFI protected circuit.
3.1.2
The battery should provide a long lifetime of service through many depletion
and recharging cycles. Nevertheless, eventually the battery may cease
maintaining an adequate charge; in this event you will have to replace the
battery. Replacement batteries (part no. 392016-000) are available from
OTS or your local dealer.
Follow these instructions to replace the battery:
1. Ensure the power switch (Fig. 1, #17) is toggled to the off position. If
the unit is connected to an external power source, unplug the power
cable from it.
2. Disconnect all devices attached to the front panel.
3. Using a Phillips screwdriver, remove and set aside the ten panel screws
and nylon washers.
4. Using the two handles, remove the front panel. The MK-III's internal
hardware and electronics are attached to the panel, so care must be
taken when handling the panel.
5. Disconnect the battery wire connector on the PCB by pulling connector
away from the mating connector.
