transmitters
6.3.1 Display of available battery
capacity
6.3.2 Charging the batteries
DRC-MJ D3 hand-held transmitters are supplied with power by the rechargeable
battery pack included in the scope of delivery or by two size AA (LR6) NiMh
rechargeable batteries. The batteries must be charged in good time with the
appropriate plug-in charger. The ambient temperature must be between +10° C
and +45° C for the charging process.
The battery capacity is shown on the screen of the DRC-MJ D3 hand-held
transmitter. The charging status of the battery corresponds to the dark surface of
the battery icon.
For a new battery, the full battery icon represents a useful operating period of
approx. 60 hours for DRC-MJ D3 hand-held transmitters when they are switched
on.
If only a residual charge is shown, connect the DRC-MJ D3 hand-held transmitter
to the charger at the next opportunity. If the battery icon is empty, the DRC-MJ D3
hand-held transmitter must be immediately connected to the charger.
The operating time that can be achieved by a DRC-MJ D3 hand-held transmitter
with one battery charge depends on the operating mode of the DRC-MJ D3 hand-
held transmitter, the ambient temperature and the age of the batteries.
Approx. 60 hours of operation can be achieved with one battery charge if a
DRC-MJ D3 hand-held transmitter is continuously switched on.
The following measures reduce power consumption:
• Change to Standby during breaks in operation (see section 8.5 on page 47).
• Switch the transmitter off (see section 8.5 on page 47).
Further measures to reduce power consumption include switching off the
background illumination and the vibration alarm (see section P1.2 on page 60).
When this battery icon is displayed, charge the batteries immediately
using the plug-in charger included in the supply.
If the batteries are not charged immediately, the battery icon will start to flash and
the DRC-MJ D3 hand-held transmitter will switch off after a few seconds. A low
battery capacity is also indicated by the vibration alarm.
Quick charging of the batteries with the DRC-MJ D3 hand-held transmitter is only
possible at ambient temperatures from +10 °C to +45 °C. If the temperature is
higher or lower than this range, the charging process is aborted and the system
automatically switches over to trickle charging.
