5. Model Plates
A model plate is attached to both the transmitter
and the receiver.
Radio remote control can only be performed with
equipment which have identical characteristics on
their model plates.
Operation of the radio remote control is without
charge in the FRG according to PTT approval
AGB-242.

7. Brief Description
The new generation of SCHWING RADIO
REMOTE CONTROLS are an advanced develop-
ment of the systems first introduced in 1983.
Radio remote controls can be retrofitted or fitted at
the factory.
Dependent on the machine model, black-and-
white or proportional controls are available.
Transmitter
The transmitter is powered by a rechargeable
nickel-cadmium battery. An inbuilt “idle state cir-
cuit” ensures optimized utilization of the battery
charge. The “idle state circuit” switches the power
supply off when no switch is operated within a
period greater than 20 seconds. The power supply
switches on again when a switch is operated. The
operating voltage is permanently monitored.
