13 OTHER FUNCTIONS ■ Tone scan The transceiver can detect the subaudible tone frequency and DTCS code in a received signal. By monitoring a signal that is being transmitted on a repeater input frequency, you can determine the tone frequency required to access the repeater. q Set the desired frequency or memory channel to be checked for a tone frequency or DTCS code. w Push and hold [TONE](7) for 1 sec. several times to activate the repeater tone, tone squelch or DTCS squelch. (TONE, TSQL or DTCS) • Rotating [DIAL] while pushing and holding [TONE](7) also selects the tone functions. e Push and hold [T.SCAN](.) for 1 sec. to start the tone scan. • To change the scanning direction, rotate [DIAL]. r When the tone frequency or DTCS code is decoded, the set mode contents are programmed with the frequency or code. • The tone scan pauses for the set period in scan pause timer (p. 108) when a tone frequency or DTCS code is detected. • The decoded tone frequency is used for the repeater tone frequency when the tone squelch is OFF. • The decoded tone frequency is used for the tone squelch frequency (CTCSS TONE) when the tone squelch is ON. • The decoded DTCS code is used for the DTCS code when the DTCS squelch is ON. 126 [DIAL] 7DSQ TONE . # CD T.SCAN Tone scan for tone squelch/ repeater tone. +DUP DTCS FM PRIO WX EMR A 1713 25 MemoName PSKIP Tone scan for DTCS squelch. +DUP DTCS DV PRIO WX EMR A 662 25 MemoName PSKIP The decimal point is blinking while tone scanning. t Push [VFO] to stop the scan. • If the scan is cancelled before the transceiver detects the tone or code, the set mode contents are not changed. • The detected tone is used for temporary operation only. The stored tone setting in memory or call channel won't be changed. NOTE: Tone frequency is over-written automatically when it corresponds with the scanning tone frequency in tone squelch mode. However, it is not over-written in memory or call channel mode.
