Note:
◆ You can select a tone frequency independent of a
CTCSS frequency.
◆ When 1750 Hz is selected, the transceiver sends a
500 ms tone burst each time transmission starts. You
cannot transmit 1750 Hz tone manually.
TONE FREQUENCY ID SCAN
This function scans through all tone frequencies to
identify the incoming tone frequency on a received
signal. You may fi nd this useful when you do not know
the tone frequency that the repeater uses.
1 While the Tone function is ON (“ ” is visible), press
and hold [AGC/T (SEL)].
• The current tone frequency appears.
2 Press [SCAN (SG.SEL)] to activate the Tone
frequency ID scan.
• While the transceiver is receiving a signal, “ ”
blinks and every tone frequency is scanned.
When the tone frequency is identifi ed, the
transceiver stops scanning and the identifi ed
frequency is displayed.
• Press [SCAN (SG.SEL)] or [CLR] to stop
scanning while the tone frequency ID scan is
active.
• Press [SCAN (SG.SEL)] again to resume
scanning.
Note: Received signals are audible while scanning is in
progress.
The data that you select in steps 1 to 8 can be stored
in memory. Refer to “Split-Frequency Channels” {page
43}.
Note:
◆ When operating through a repeater, over deviation caused
by speaking too loudly into the microphone can cause your
signal to “talk-off” (break up) through the repeater.
◆ To check the tone frequency stored in a memory channel,
recall the desired memory channel and press [AGC/T
(SEL)].
TRANSMITTING A TONE
In general, FM repeaters require the transceiver to
transmit a sub-audible tone to prevent other repeaters
on the same frequency from locking each other up.
The required tone frequency differs among repeaters.
Repeaters also differ in their requirements for either
continuous or burst tones. For the appropriate
selections for your accessible repeaters, consult your
local repeater reference.
After completing the tone settings, pressing and
holding Mic [PTT] causes the transceiver to transmit
the selected tone. If you have selected a 1750 Hz
tone, the transceiver sends a 500 ms tone burst each
time transmission starts.
Note: If you store tone settings in a memory channel, you need
not reprogram each time. Refer to “MEMORY FEATURES”
{page 43}.
■ Activating the Tone Function
1 Confi rm that FM mode has been selected on
the VFO(s) {page 10}.
• When using 2 VFOs, you must select FM
mode on both VFOs.
2 Press [AGC/T (SEL)].
• “
” appears.
Note: You cannot use the Tone function with the CTCSS
function.
■ Selecting a Tone Frequency
1 While “ ” appears (Tone function is ON), press
and hold [AGC/T (SEL)].
• The current tone frequency appears.
The default is 88.5 Hz.
2 Turn the MULTI/CH control to select the desired
tone frequency.
• The available tone frequencies are listed in
the table below.
3 Press and hold [AGC/T (SEL)] or press [CLR]
to complete the setting.
