Be sure to switch power to the transmitter OFF every time before
changing the carrier frequency. The new carrier frequency will not be
activated before you switch the transmitter back ON. (If you change the
carrier frequency while the transmitter is ON, the transmitter will remain
tuned to the old carrier frequency.)
If you wish to set up a multichannel system, read section 1.2 Multichannel
Systems in Part V first.
