SUBAUDIBLE TONES 9

DSetting subaudible tones for tone squelch operation

Separate tone frequencies can be set for tone squelch operation rather than repeater operation (the same range of tones is avail- able— see below). Like the repeater tones, these are set in set mode.

qSelect VFO or memory channel.

wPush [A•FUNC] + [8•SET] to enter set mode. e Push [∫] or [√] several times until “Ct” ap- pears when selecting CTCSS, or “dt” ap-

pears when selecting DTCS.

•“ ” flashes when selecting CTCSS, or “ D ” flashes when selecting DTCS.

rRotate [VOL] to select the desired subaudible tone.

tPush [#•ENT ] to program the selected tone and exit set mode.

When SET MODE is selected from memory mode.

yPush [C•MR] for 1 sec. after [A•FUNC] is pushed.

•3 beeps are emitted.

•VFO mode is selected automatically.

uPush [C•MR] for 1 sec. after [A•FUNC] is pushed.

• 3 beeps are emitted.

Steps y and u are necessary when overwriting the memory con- tents permanently. The set tone frequency is used for temporary operation only, therefore,these steps are not necessary.
