B. Servo reverse
The Focus 4 F.M transmitter is equipped with servo reversing on all 4channels.
E. Innovative MASTER-STUDENT trainer system
Pulling down the trainer switch will switch over the control to the student transmitter.
Releasing the switch will enable master transmitter to resume control. When attaching the
trainer cable (optional item sold separately. Spare part # 8310 : one way trainer cord) the cable
must be connected to the correct side as the .master side should be connected with the master
transmitter. The purpose is obvious. Connected properly, the student transmitter cannot be
activated even if it is accidentally turned on, a unique feature not present in other systems.
( Note : Leaving the reverse switch in the middle will cause the radio to work
erratically so please make sure that the switches are all pushed to the furthest end. )
C. Aileron and elevator & rudder & throttle adjustable travel volume (A.T.V.)
This function adjusts the servo left and right throws on aileron and elevator and
rudder and throttle. The rate setting range is 30% to 110%.
