8 TONE SQUELCH AND POCKET BEEP r W hen receiving a signal that includes a matched tone or code, the squelch opens and the signal can be heard. When the pocket beep function is activated. • Beep tones sound and " " blinks. To stop the beeps and blinking, push any key. • When the received signal's tone/code does not match, the squelch does not open. However, the signal indicator shows the signal strength. • To open the squelch manually, push and hold [MONI]. t P ush [PTT] to answer. ■ Tone scan 1 By monitoring a signal from a repeater, pocket beep or 2 squelch function operation, you can determine the subaudi- 3 ble tone required to access the repeater or open the squelch. 4 q S et a frequency to be checked for a tone frequency or 5 DTCS code. w P ush [FUNC](M), and then [TONE](1). 6 • Repeat step w several times to activate a desired tone function. 7 • The tone scan can be made even if the tone function is not se- lected. 8 e P ush [FUNC](M), and then [T.SCAN](3) to start a tone scan. 9 • To change the scan direction, push [] or []. 10 r W hen a tone frequency or DTCS code is matched, the squelch opens and the tone frequency or code is tempo- 11 rarily programmed into the selected mode. 12 • When a tone frequency or DTCS code is detected, the tone scan pauses according to the scan resume setting (p. 30) 13 • The decoded CTCSS tone frequency or DTCS code is used ac- 14 cording to the selected tone function type in step w. - No indication : Cannot be used for operation. 15 -" " : CTCSS tone encoder (repeater tone) 16 -" " : CTCSS tone encoder/decoder -"D " : DTCS tone encoder/decoder 17 t T o cancel the scan, push any key except 18 [MONI] or [FUNC](M). 19 34
