With repeater shift activated, you can temporarily reverse the transmit and receive
frequencies by pressing the [
B
](
REV
) key. The “
–
” icon will blinks while “Reverse” shift
is activated. Press the [
B
](
REV
) key again to revert to the “Normal” shift direction.
10.
When finish a repeater operation, set the repeater shift to simplex by pressing [
A
](
RPT
)
key, and disable the CTCSS tone encoder by pressing [
C
](
TON
) key.
11.
On many transceiver versions, the Automatic Repeater Shift (ARS) feature is enabled
at the factory. This feature 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 settings for the ARS, use Menu #01 (
144 ARS
) or
Menu #02 (
430 ARS
) (see page ??).
If your local repeaters need a 1750-Hz burst tone for access (typically in Europe), press and
hold the [
HOME
] key to transmit the burst tone.
CTCSS Encoder and Tone Squelch Operation
Many repeaters require a CTCSS Encode or 1750 Hz Burst Tone in order for the repeater to
be activated. The CTCSS Tone Squelch feature (CTCSS “Decoder”), moreover, allows you to
monitor silently for calls on busy channels, with your receiver’s Squelch only opening up
when a signal bearing the matching CTCSS tone appears on your frequency.
1.
Press the [
F
] key momentarily, then rotate the
SEL
knob, as needed, until Operating
Function Row [
RPT
,
REV
,
TON
].
2.
Press and hold the [
C
](
TON
) key for one second to recall the Menu # 48 (
TONE FREQ
),
then rotate the
DIAL
knob to select the CTCSS tone frequency, as needed. When done,
press and hold the [
C
](
TON
) key for one second so save the new setting and exit to
normal operation.
3.
Press the [
C
](
TON
) key once to activate the Tone Encoder (the “
T
” icon will appear on
the display). When you transmit, the Subaudible tone will be superimposed on your
signal, allowing repeater access.
4.
For CTCSS Encode/Decode operation, press the [
C
](
TON
) key once more; the “
TSQ
”
indicator will replace the “
T
” indication on the display. The receiver will become silent,
unless a station bearing a CTCSS tone matching that of your transceiver appears on
frequency. When this happens, the Squelch will open and normal reception will
commence.
5.
Press the [
C
](
TON
) key once mode to cancel CTCSS Tone Squelch operation (the “
TSQ
”
icons will disappear).
DCS Operation
Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
advanced tone system that is less susceptible to false triggering than CTCSS. A DCS
Encoder/Decoder is built into your transceiver, and operation is very similar to that just
described for CTCSS.
1.
Set the desired DCS code via Menu #23 (
DCS CODE
).
2.
Press the [
F
] key momentarily, then rotate the
SEL
knob, as needed, until Operating
Function Row [
RPT
,
REV
,
TON
].
3.
Press the [
C
](
TON
) key three thimes to activate the DCS Encoder/Decoder (the “
DCS
”
icon will appear on the display). The receiver will remain muted until a matching DCS
code is received on an incoming signal.
4.
Press the [
C
](
TON
) key once to cancel the DCS (the “
DCS
” icon icons will disappear).
ARTS
TM
(Auto Range Transpond System) Operation
The ARTS
TM
system uses DCS signaling to inform you when you and another ARTS-
equipped station are within communications range.
1.
Press the [
F
] key momentarily, then rotate the
SEL
knob, as needed, until Operating
Function Row [
SSM
,

].
2.
Press the [
C
](
ART
) key to activate the ARTS.
3.
Your display will change to “
out range
” to indicate the beginning of ARTS operation.
Every 15 seconds, your radio will transmit a “polling” call to the other station. When
that station responds with its ARTS polling signal, your display will change to “
