The operator controls the radio-controlled crane with the DRC-MJ D3 hand-held
transmitter.
Before starting work, the operator must carry out the inspections and function
checks listed in the crane user manual/assembly instructions and must be satisfied
that the installation is in safe operating condition.
When the unit is switched off, no icons appear on the screen, the LED is off. Press
the STOP button to switch the DRC-MJ D3 hand-held transmitter on.
The "DEMAG" logo first appears on the display. When a connection to the DRC
radio receiver has been established, the following must be displayed:
• Crane identification of the assigned DRC radio receiver
• Icon to display the radio signal quality
• Icon to display the battery capacity

The radio system performs a self-test when it is switched on. The installation is
then ready for operation if no error statuses are displayed.
Fault elimination is described in section 10.
In addition, the operator must check the following before starting work:
• Battery capacity
• Radio signal strength
• Displayed crane ID and relevant crane 6.4.2.1
