D Available tone frequency list
NOTE: The transceiver has 50 tone frequencies and con-
sequently their spacing is narrow compared to units having
38 tones. Therefore, some tone frequencies may receive
interference from adjacent tone frequencies.
To prevent interference from adjacent tone frequencies, using
the frequencies as in the following table, is recommended.
D Calling a waiting station using pocket beep
A subaudible tone matched with the stations CTCSS tone fre-
quency or 3-digit DTCS code with polarity is necessary. Use
