6.2 Master/Master 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 transmitter-A to gain control of receiver-
B, transmitter-B must first release its control of
receiver-B by first rotating the selector switch to
B position and then pressing the PITCH
pushbutton for up to 2 seconds. This action
releases transmitter-B control of receiver-B.
Transmitter-A is then able to take control of
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 transmitter-B presses the PITCH pushbutton (refer to the
following diagram).
