B, or A+B position for independent or simultaneous operation.
3. At the beginning of each shift prior to turning on the transmitter power, always check to
see if the selector switch is correctly positioned for the intended receiver or receivers.

means that when PITCH pushbutton is pressed, executing the START command on the
other transmitter within this 2-second grace period has no effect. To gain control of the
other receiver, you must first wait for up to 2 seconds after the PITCH pushbutton is
pressed on the other transmitter and then execute the START command.
