Transmitting TOT Setting
The TOT function is used to prevent a too long transmission. This function
temporarily blocks transmissions if the radio has been used beyond the
maximum time permitted. Once reached the preset timer, the radio will
be forced in reception mode.
This unit can set OFF/30-270 seconds continued transmitting limit, it will
send out warning sound when the limit transmitting time is coming.
Procedure:
Press
MenU
and turn the encoder to item 12:
“012 TOT?”
will be displa-
yed. Press
enTer
: the display shows
”OFF”
(TOT off). Turn the encoder to
choose
“OFF~270”
, then press
enTer
to confirm and
VFO/Mr
to exit.
Voice Function (only in English)
With this function, you activate a voice that informs about any operation/
selection you are doing.
Press
MenU
and turn the encoder to menu item 14: the display will show
“014 VOICE?”
. Press
enTer
.
Turn the encoder to choose
“ENG”
; press
enTer
as confirmation and
VFO/Mr
to exit.
OFFSET DIFFR
This function is used to determine the difference (Potential Difference)
between sending frequency and receiving frequency.
In frequency mode, press
MenU
and turn the encoder to item 15; the
display will show
“015 DIFFR?”
. Press
enTer
to set the frequency with
the keypad or by rotating the encoder.
The VHF range is 00.000-38.000(MHz) and the UHF range is 00.000-
69.950(MHz).
Press
enTer
to confirm and
VFO/Mr
to exit.
This function can only be enabled in VFO mode. The maximum offset de-
pends on the selected frequency range.
Selecting the CTCSS tones and DCS codes
Set the CTCSS tones to ignore unwanted signals from other users of the
same frequency.
CTCSS tones enable the radio to communicate with the users that are
tuned on the same channel and have set the same CTCSS tone.
The CTCSS tones available are 50, while DCS codes are 105I and 105N.
Procedure:
Press
MenU
and
#T-r
keys, the display will show
“016 C-CDC?”
.
Press
enTer
and turn the encoder to select desired CTCSS (OFF-254.1).
Press
*
to switch CTCSS and DCS. The DCS range is OFF-D754N.
Press
enTer
to confirm and
VFO/Mr
to exit.
Setting the receiver CTCSS/DCS (R-CDC)
Press
MenU
and turn the encoder to select
“017 R-CDC?”
.
Press
enTer
and turn the encoder to select desired CTCSS (OFF-254.1).
Press
*
to switch CTCSS and DCS. The DCS range is OFF-D754N.
Press
enTer
to confirm and
VFO/Mr
to exit.
Setting the transmitting CTCSS/DCS (T-CDC)
Press
MenU
and turn the encoder to select
“018 T-CDC?”
.
Press
enTer
and turn the encoder to select desired CTCSS (OFF-254.1).
Press
*
to switch CTCSS and DCS. The DCS range is OFF-D754N.
Press
enTer
to confirm and
VFO/Mr
to exit.
note:
when you set the Menu of DCS codes, press [#] and you can select OFF-
D754I (Inverted).
+/- Frequency shift direction (for communications
through repeaters)
This function can only be enabled in VFO (frequency) mode.
In frequency mode, press
MenU
and
*
: the display will show
“019
S-D?
”
.
Press
enTer
and the display shows
“S-D 0”
(same frequency); turn the
encoder and you can select
“S-D+”
or
“S-D-“
. Press
enTer
to confirm
and
VFO/Mr
to exit.
Selecting the Frequency Step
This function can only be enabled in VFO (frequency) mode.
In frequency mode, press
MenU
and turn the encoder to item 20:
“020
STEP?
”
will be displayed.
Press
enTer
and turn the encoder to select the frequency stepping: 5k,
10k, 6.25k, 12.5k, 25k. Press
enTer
to confirm and
VFO/Mr
to exit.
