277 POCKET BEEP AND TONE SQUELCHD Available tone frequency listNOTE: The receiver has 51 tone frequencies and conse-quently their spacing is narrow compared to units having38 tones. Therefore, some tone frequencies may receiveinterference from adjacent tone frequencies.D Available DTCS code listD Calling a waiting station using pocket beepA subaudible tone matched with the station’s CTCSS tone fre-quency or 3-digit DTCS code with polarity is necessary. Usethe tone squelch on the next page or a subaudible tone en-coder (pgs. ??, ??). Tone/DTCS squelch operationThe tone or DTCS squelch opens only when receiving a sig-nal with the same pre-programmed subaudible tone or DTCScode, respectively. You can silently wait for the specified sig-nal using the same tone.q Set the operating frequency in FM mode.w Program the CTCSS tone frequency or DTCS code in setmode.• See steps w to y on p. ?? for programming details.e Push [MONI•T/T-SCAN] for 1 sec and rotate [DIAL] until“ ” or “ ” appears in the function display.r When a signal with the matched tone is received, thesquelch opens and the receiver emits audio.• When the received signal includes an unmatched tone, thesquelch does not open. However, the S-meter indicator showsthe received signal strength.• To open the squelch manually, push [MONI•T/T-SCAN].t To cancel the tone squelch, push [MONI•T/T-SCAN] for 1sec and rotate [DIAL] until “ ” or “ ” disappears.02302502603103203604304705105312513113213414314515215515616224524625125225526126326526627135636436537141141241342343143250651652352653254656560661262405406507107207307411411511612216517217420521222322522624324427430631131532533133234334635144544645245445546246446546650362763163265466266470371272373173273474375467.069.371.071.974.477.079.782.585.488.591.594.8097.4100.0103.5107.2110.9114.8118.8123.0127.3131.8136.5141.3146.2151.4156.7159.8162.2165.5167.9171.3173.8177.3179.9183.5186.2189.9192.8196.6199.5203.5206.5210.7218.1225.7229.1233.6241.8250.3254.1
