The signal key is of two-stage self-resetting design. The first stage activates the
acoustic signal in the crane receiver. The second stage activates an additional
signal for the crane control system to carry out the hoist limit switch test. For
checking the limit switch, the instructions contained in the operating instructions
of the radio-controlled crane must be applied.
The function keys are of single-stage self-resetting design. Various additional func-
tions are controlled depending on the design of the radio receiver and the crane
control system. These functions are described in the operating instructions of the
receiver or the crane installation.
At the end of the shift or in the event of extended breaks, DRC-10 hand-held
transmitters must be switched to Standby mode by the illustrated key sequence
to protect the installation against unauthorized use and to reduce power consump-
tion of the DRC-10 hand-held transmitter. The time after the end of the shift or
longer breaks should be used to re-charge the batteries by connecting them to
the charger unit.

If a hand-held transmitter is not used for some time (several weeks), the batter-
ies should first be fully charged and then removed from the hand-held transmitter
(see section 7.4.5). The batteries can be stored for several months when they are
charged. If required, the charging process should be repeated after some time.
The function and display of the radio control system are determined by the operat-
ing status of the hand-held transmitter. The operating status of the transmitter is
transmitted to the crane control system.
Display and radio connection are de-activated. Power consumption of the hand-
held transmitter in this status is less than the natural discharge of the batteries.
Switch on the hand-held transmitter and briefly actuate the STOP key.
After switching-on, the hand-held transmitter is in Stop mode, the LED in the trans-
mitter is permanently lit red.
The display shows STOP. No travel commands are transmitted in STOP mode.
The EMERGENCY stop contact in the receiver (crane switch for DRC-DR) is open.
The radio connection to the receiver is maintained. Following a timeout period of
5 minutes without any key actuation, the hand-held transmitter will automatically
switch to Standby mode.
The LED in the keyboard flashes green. The crane identification of the assigned
crane and the icon for the radio connection are shown in the display. In Run mode,
the hand-held transmitter is fully functional for crane operation, see section 7.2.
Crane operation can be started with the On key in "STOP" and "Standby" mode,
see section 7.2.1.
Following a timeout period of 30 minutes without any key actuation, the hand-held
transmitter will automatically switch to Standby mode.
Hold down
Transmitter locked, Standby mode.
