DTCSS

10 POCKET BEEP AND TONE SQUELCH

zSet the operating frequency.

TSQLS x Program the CTCSS tone frequency or DTCS code in set mode.

➥Push [SET B(D-OFF)] to enter set mode.

➥ Push [SET B(D-OFF)] or [ENT C(T-OFF)] several times until “CT” for tone squelch or “DT” for DTCS squelch appears.

•“T SQL” blinks when tone squelch (“CT”), or “DTCS” blinks when DTCS squelch (“DT”) is selected.

➥Push [Y]/[Z] to select the desired tone fre- quency or DTCS code.

➥Push [SET B(D-OFF)] to select “DTP” then push [Y]/[Z] to select the DTCS polarity.

➥Push [CLR A(MW)] to exit set mode.

cPush [FUNC] then push [DUP+ 8(TSQLS)]

or [MID 5(DTCSS)] to turn ON the pocket beep with tone squelch or DTCS squelch, re- spectively.

vWhen a signal with the matched tone is re- ceived, the transceiver emits beep tones for 30 sec. and blinks “S.”

bPush [PTT] to answer or push [CLR A(MW)] to stop the beeps and blinking.

•“S” disappears and cancels the pocket beep function automatically.

nTo cancel the tone squelch or DTCS squelch function, push [FUNC] then [ENT C(T-OFF)].

•“T SQL” or “DTCS” disappears

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 recom- mended.

DCalling a waiting station using pocket beep

A subaudible tone matched with the station’s CTCSS tone fre- quency or 3-digit DTCS code with polarity is necessary. Use the tone squelch on the next page or a subaudible tone en- coder (pgs. 22, 23).
