Radio Control System
Should the operator switch off the transmitter with the STOP pushbutton, following steps
have to be carried out for further radio transmission :
1. Switch off the transmitter via the key switch.
2. Unlock the STOP pushbutton by turning.
3. Switch the transmitter on again via the key switch.
4. Press the “(Crane) On” button.
Note :
Use the key switch to switch the transmitter on and off. Use the STOP pushbutton only
in case of an emergency or any disturbances within the working range
Automatic Switch-OFF ( APO Function )
For safety reasons we have equipped the transmitter with an automatic switch-OFF
(APO = Automatic Power Off function). The transmitter is automatically put out of circuit
after 15 minutes of non-use.
The automatic switch-OFF also saves battery power.
Note :
The automatic switch-OFF (APO function) does not relieve the operator of his
responsibility to turn OFF the transmitter when not in use !
The transmitter can be reactivated by means of the "ON“ pushbutton.
Slewing Gear Release
Note :
This function is available only by radio control systems for construction cranes.
Whenever the command "slewing gear release" is actuated by means of the radio
control, it is important that the respective check be made.
Due to the above, a clearly visible indicator lamp should be installed on the crane –
possibly a flashing one.
