9 SUBAUDIBLE TONES

‘Tone squelch

DOperation

The tone squelch opens only when receiving a signal containing a matching subaudible tone. You can silently wait for calls from group members using the same tone.

qSet the operating frequency.

•Set the AF and squelch to the desired level as the normal operation. w Set the desired subaudible tone in the set mode.

•See right for programming.

ePush [1•TONE] after [A•FUNC] is pushed.

• Repeat several times until “ ” appears when selecting CTCSS, or “ D ” appears when selecting DTCS.

rWhen the received signal includes a matching tone, squelch opens and the signal can be heard.

•When the received signal’s tone does not match, tone squelch does not open, however, the S-indicator shows signal strength.

•To open the squelch manually, push and hold [SQL].

tOperate the transceiver in the normal way.

yTo cancel the tone squelch, push [1•TONE] after [A•FUNC] is

pushed.

• Repeat several times until “ ” or “ D ” disappears.

NOTE: The transceiver has 50 tone frequencies and conse-

quently their spacing is narrow compared to units having 38

tones. Therefore, some tone frequencies may receive interfer-

ence from adjacent tone frequencies.

To prevent interference from adjacent tone frequencies, using the frequencies as in the following table, is recommended.
