Tone Search Scanning
In operating situations where you don’t know the CTCSS
tone being used by another station, you can command the
radio to listen to the incoming signal and scan in search of
the tone being used. To scan for the CTCSS tone in use:
1. Press the [ F
] key momentarily, then rotate the
MEM/
VFO CH
knob, as needed, until Multi Function Row
“e” [ TON , ----- , TDCH
] appears on the display.
2. Press the [ A
](
TON
) key to activate CTCSS Encoder/De-
coder; (the “ TSQ ” icon will appear on the display)
3. Press the [ C
](
TDCH
) key to start scanning for the in-
coming CTCSS tone.
4. When the radio detects the cor-
rect tone, it will halt on that tone,
and audio will be allowed to pass
5. The CTCSS tone detected will be
stored as the “current” tone, so it may be used for memory
storage purposes, and you may now exit to normal op-
eration.
you press the [
A
](
TON
) key repeatedly, you will ob-
serve “ TSQ ” (CTCSS Encode/Decode), “ DEN ” (Digi-
tal Coded Squelch, Encode), followed by “
DCS
”
(Digital Coded Squelch, Encode/Decode). One ad-
ditional press will disable all repeater-access tone
systems. See the next section for a discussion of DCS
operation.
• If the default repeater access tone is not appropriate
for the repeater on which you are operating, it may
be set easily:
1. Press and hold the [ A
](
TON
) key for one second.

3. When done, press and hold the [
F ] key for one
second to save the new setting and exit to normal
operation.
5. With repeater shift activated, you can temporarily re-
verse the transmit and receive frequencies by pressing
the [
B
](
REV
) key in the Multi Function Row “d” [
RPT ,
REV , VOX
]. The “
– ” icon will blink while “Reverse” shift
is activated. Press the [ B
](
REV
) key again to revert to
the “Normal” shift direction.
6. On many transceiver versions, the Automatic Repeater
Shift (ARS) feature is enabled at the factory. This fea-
ture automatically activates the appropriate repeater shift
when you are operating inside the designated 144 MHz
or 430 MHz FM repeater sub-bands in your country. If
you wish to change the On/Off settings for the ARS, use

(see page 56).
If your local repeaters need a 1750-Hz burst
tone for access (typically in Europe), press and
hold in the front panel’s
[

key to trans-
mit the burst tone (FM mode only).
