2) Activating of the CTCSS function and selection of the CTCSS tone:
The CTCSS function serves to suppress signals of unwanted stations on the actual
channel. If this function is active the unit works as follows:
The other station is only audible in the speaker, if it adds to its modulation signal a
certain tone in the frequency range from 67 Hz to 250 Hz with low level.
In transmit mode the unit adds itself to its modulation signal a tone of the same fre-
quency so that the muting device of the counter station can open also.
If the function is inactive you can hear every station on the channel, and in transmit
mode no tone is added to the modulation signal.
