39SUBAUDIBLE TONES9■ Tone squelchD OperationThe tone squelch opens only when receiving a signal con-taining a matching subaudible tone. You can wait for callsfrom group members using the same tone and not hear othersignals.q Set the operating frequency.• Set the volume and squelch to the desired level as the normal op-eration.w Set the desired subaudible tone in SET MODE.• See page 40 for programming.e Push [FUNC], then push [TONE](1).• Repeat several times until “ ” appears when selecting CTCSS,or “ ” appears when selecting DTCS.r When 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 squelchdoes not open, however, the S-indicator shows signal strength.• To open the squelch manually, push and hold [MONI].t Transmit in the normal way.y To cancel the tone squelch, push [FUNC] and [TONE](1).• Repeat several times until “ ” or “ ” disappears.NOTE: The transceiver has 50 tone frequencies and con-sequently their spacing is narrow compared to units having38 tones. Therefore, some tone frequencies may receiveinterference from adjacent tone frequencies.To prevent interference from adjacent tone frequencies,using the frequencies as in the following table, is recom-mended.• Recommended CTCSS frequencies (Unit: Hz)• Recommended DTCS codes02302502603103204304705105406507107207307411411511612513113213414315215515616216517217420522322624324424525126126326527130631131533134334635136436537141141241342343143244546446546650350651653254656560661262462763163265466266470371272373173273474375467.069.371.974.477.079.782.585.488.591.594.897.4100.0103.5107.2110.9114.8118.8123.0127.3131.8136.5141.3146.2151.4156.7162.2167.9173.8179.9186.2192.8203.5210.7218.1225.7233.6241.8250.3DPushTONE1FUNCACTCSS DTCSD
