Warning device function
Radio-controlled cranes must be provided with a warning device (acoustic or
optical). The operator can activate this warning device by means of the signal
button on the button panel of the DRC-MJ D3 hand-held transmitter to warn
individuals in the vicinity of the crane and/or load before starting any crane
movements.
The warning device must also be used if the operator intends to check the
assignment between the hand-held transmitter and the DRC radio receiver on the
crane by means of a command on the DRC-MJ D3 hand-held transmitter.
Radio control system range
The crane operator may only use the range of the radio control system to the
extent that he can freely monitor the danger zone of the crane movements.
The range of the DRC-MJ D3 hand-held transmitter is limited and can be
additionally reduced by ambient conditions. The range may also be limited if the
available frequency range is being used by other radio transmitters. The quality of
the radio signal is shown on the screen of the DRC-MJ D3 hand-held transmitter.
If poor connection quality is displayed, unintended interruptions of the controlled
movements can occur.

A separate rechargeable battery is included in the scope of delivery for
the DRC-MJ D3 hand-held transmitter. It has to be placed into the battery
compartment of the hand-held transmitter with the correct polarity (see also
diagram in section 8.6.5).
Since new rechargeable batteries are only partially charged when they are
delivered, they must be charged before they are put into operation for the first time
by connecting them to the plug-in charger (see section 6.3.2).
DRC radio receivers must be installed in accordance with the relevant user
manual/assembly instructions and connected according to the circuit diagram for
the installation. Comply with the instructions and measures described in the user
manual/assembly instructions to put the DRC radio receiver into operation.
A unique crane ID/number must be selected (a 3-figure number is recommended)
and applied to the crane according to section 6.4.4 for cranes that are equipped
with the radio control system.
