Transmitter-A Transmitter-B Transmitter-B

b. Once the transmitter is locked on to both receivers, rotate the selector switch to either

A, B, or A+B position for independent or simultaneous operation.

c. At beginning of each shift prior to turning on the transmitter power, always check if the

selector switch is correctly positioned for the intended receiver or receivers.

d. For safety, there is a 2-second grace period followed after executing the PITCH

command. What this means is that after PITCH pushbutton is pressed, executing the

START command on the other transmitter within this 2-second grace period is

ineffective. In order to gain control of the other receiver you must first wait for up to 2

seconds after the other transmitter presses the PITCH pushbutton and then for you to

execute the START command thereafter.

6.3. Master/Slave Tandem Operation (Tandem

models)

a. 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 of its receiver (receiver-B). Master transmitter is then able to

take control of the Slave receiver (receiver-B) by first rotate the selector switch to B position

and then execute the START command. Make sure the START command is executed 2.0

seconds after Slave transmitter presses the PITCH pushbutton (refer to diagram below).
