REPEATER OPERATION

■ Subaudible tones

To be accessed, some repeaters require subaudible tones on
the input signal. Subaudible tones are added to your normal
signal and must be set in advance.

NOTE: The transceiver has 50 tone frequencies and con-
sequently their spacing is narrow compared to units having
38 tones. Therefore, systems using some tone frequencies
may receive interference from signals using adjacent tone
frequencies.

Tone scan function: When you don't know the subaudible
tone used for a repeater, the tone scan is convenient for de-
tecting the tone frequency. (p. 48)
