For such European repeaters, perform the following. q Set the receive frequency (repeater output frequency). w Set the shift direction of the transmit frequency. (–DUP or DUP; see p. 22 for details.) e While pushing [PTT], push and hold [CALL] for 1 to 2 sec. to transmit a 1750 Hz tone burst signal. • Pushing [PTT] 2 times quickly also transmits a 1750 Hz tone.
REPEATER OPERATION 8 ■ Auto repeater function (U.S.A. version only) D Frequency range and offset direction The U.S.A. version automatically activates the repeater settings (duplex ON/OFF, duplex direction, tone encoder ON/OFF) when the operating frequency falls within or outside of the general repeater output frequency range. The offset and repeater tone frequencies are not changed by the auto repeater function, reset these frequencies, if necessary. q Select VFO mode with [V/M]. w Push [V/M] for 2 sec.
9 SUBAUDIBLE TONE OPERATION ■ Tone squelch operation D Operation The tone squelch opens only when receiving a signal containing a matching subaudible tone. You can silently wait for calls from group members using the same tone. q Set the operating frequency. w Set the desired CTCSS tone in set mode. • See right for programming. e Push [V/M] for 2 sec. to enter set mode. r Rotate [DIAL] until “T/TSQL” appears. • “T/SQL” disappears after 1 sec. and “tO” appears.
SUBAUDIBLE TONE OPERATION 9 ■ Pocket beep operation ■ Tone scan This function uses subaudible tones for calling and can be used as a “common pager” to inform you that someone has called while you were away from the transceiver. The transceiver can detect the subaudible tone frequency 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.
10 OTHER FUNCTIONS ■ Set mode D Set mode items Set mode is used for programming infrequently changed values or conditions of functions. v In addition, this transceiver has an expanded set mode which is used for programming more infrequently changed values or conditions of functions. When turning OFF the expanded set mode, only half of the set mode items are displayed for simpler operation. D Expanded set mode ON/OFF q Push [V/M] for 2 sec. to enter set mode. w Rotate [DIAL] until “EXPAND” appears.
OTHER FUNCTIONS 10 ■ Dial select step ■ Beep tones This transceiver has a 1 MHz tuning step for quick frequency setting.

The confirmation beep tones, which sound each time a switch is pushed, can be turned ON or OFF, as desired. q Push [V/M] for 2 sec. to enter set mode. w Rotate [DIAL] until “BEEP” appears. D Setting dial select step • “BEEP” disappears after 1 sec. and “bE” appears. q Select VFO mode with [V/M].
10 OTHER FUNCTIONS ■ Auto power-off function ■ Monitor switch function The transceiver can be set to automatically turn OFF after a specified period in which no switch is pushed. The monitor switch can be set as a sticky switch. When set to the sticky condition, each push of [SQL] toggles the monitor function on and off. 120 min., 90 min., 60 min., 30 min. and OFF can be specified. The specified period is retained even when the transceiver is turned OFF by the auto power-off function.
OTHER FUNCTIONS 10 ■ Dial speed acceleration ■ Lock function effect The dial speed acceleration automatically speeds up the tuning dial speed when rotating the [DIAL] rapidly. The lock function prevents accidental frequency changes and accidental function access. q Push [V/M] for 2 sec. to enter expanded set mode. w Rotate [DIAL] until “SPEED” appears. While the lock function is ON, [POWER], [VOL], [SQL] and [PTT] can still be accessed.
10 OTHER FUNCTIONS ■ Channel indication mode ■ Partial reset Channel indication mode is used to simplify operation. In this mode only pre-programmed memory channel numbers are displayed and functions are limited ([POWER], [PTT], [SQL], [VOL], [LOCK], scanning and the tuning dial are functional). If you want to initialize the operating conditions (VFO frequency, VFO settings, set mode contents) without clearing the memory contents, a partial resetting function is available for the transceiver.
