6.3 Master/Slave Tandem Operation (Tandem Systems
Only)
1. To gain control of one or both receivers, first
rotate the selector switch to either A, B or A+B
position and then execute the START command
to activate the receiver MAIN relays inside
receiver A, receiver B, or both receivers
(depending on the selector switch position). In
order to gain control of a receiver, the PITCH
pushbutton on the other transmitter must be
pressed prior to your takeover. For example, in
order for Master transmitter to gain control of the
Slave receiver (receiver-B), Slave transmitter
must first release control of its receiver (receiver-
B) by pressing the PITCH pushbutton for up to
2.0 seconds. This action releases Slave
transmitter control from its receiver (receiver-B).
Master transmitter is then able to take control of
the Slave receiver (receiver-B) by first rotating
the selector switch to B position and then
executing the START command. Make sure the
START command is executed 2 seconds after the PITCH pushbutton is pressed on the
Slave transmitter (refer to the following diagram).
