13.2 - ONE MASTER TRANSMITTER SYSTEMS
The MASTER transmitter has got a crane selector “1 / 1+2 / 2”, while the SLAVE transmitter has
only got a release “R” push button.
When a TANDEM operation is needed, the operator of the MASTER transmitter must need that the
SLAVE transmitter operator must release the RECEIVER 2. In order to do it, it has to be pressed
simultaneously the release “R” push button and the START button. The transmitter will send to the
RECEIVER 2 the liberation order, remaining disconnected and ready to accept a new ID code.
At this stage, the position “1+2” may be selected in the MASTER transmitter and then press the
START button until the Green LED is switched on and it will send the new ID code. Both receivers, 1
and 2, will then be started and ready to TANDEM operation.
When TANDEM operation has finished, the MASTER transmitter must select position 1 again and
press the START button. By doing this, RECEIVER 2 is again ready to be used by the SLAVE
transmitter, and the MAESTRO transmitter only controls RECEIVER 1.
