Depending on the module type that you have fitted you will have two dials on the
back or a crystal in the module (found by taking the module out of the set).
If you have the two dials read off the numbers. The first number will be
multiplied by 10 (ie 6= 60) the second number will added to the first (ie 4
giving channel 64). If you have a crystal please refer to our 35MHz Frequency Table which will give you the correct channel for Tx Working Frequencies (i.e 35.040 =
Channel 64).
