➥ For communication between F300/F400/S series
and F3/F4/S series, make sure that the F3/F4/S series power saver settings are set to the same values
as the F300/F400/S series Tone Start Timing settings.
➥ When using the UT-109/UT-110 for non-rolling type
scrambling there are 32 available scramble codes.
In the memory CH screen, 1 to 255 can be input as
codes however, many of these codes are identical
(adding 32 to a code results in the same scramble
code). The following groups of codes are the same:
1to32
(33 to 64)
(65 to 96)
(97 to 128)
(129 to 160)
(161 to 192)
(193 to 224)
(225 to 255)
➥ When using the UT-110 for rolling type scrambling
similar but different codes will often result in a
match. To avoid this, use codes that are sufficiently
different (generally speaking codes that are separated by values of 20 or more will not match).
➥ When using the UT-110 for rolling type scrambling
and a channel is in the scramble ON condition, if a
received signal includes no simultaneous tone, the
receiving station automatically enters the through
condition and the transmission can be monitored.
How ever, when non-rolling type scrambling is set,
simultaneous tone are not used and therefore signals from other stations are received with modulation reversed.
Below examples are not always needed settings,
but will be useful in cases after transmitting a synchronous tone to notify operator of times to start
talking.

SCRAMBLER TYPE (UT-110 only)
Set the UT-110 Rolling type scrambler as UT-109 Nonrolling type. As UT-110 and UT-109 have dif ferent code
settings, they are not compatible.
By selecting Non-rolling type in this item, you can use
UT-110 as UT-109.

IC-F3GT/GS, IC-F4GT/GS SERIES CLONING NOTES
M Setting examples
M IC-F3GT/GS, IC-F4GT/GS series
➥ Generally, channels with voice scrambler settings
should have the power save function in the Edit
Memory CH screen turned OFF.
➥ When you want to use the voice scrambler function
on channels in which the power saver function is
ON, set the Tone Start Timing in the Common 2
screen to 1.100.
• In above case, non-scrambling voice will be transmitted
approx. 1 sec. after pushing PTT.
When using the UT-110 as rolling type scrambler unit
to keep the highest level of privacy, the ‘LOG IN’ function provides full time scrambling communications.
M Using ‘LOG IN’ function
• For LMR:
➥ In the Common 2 screen, set the Tone Start Timing
to 1.100.
➥ In the DTMF Autodial screen, set the LOG/ID code
to 5 and the 1st Timer to 0.700.
➥ In the memory CH screen, set necessary channels
to LOG IN (L-IN).
NOTE: At these settings, when the period from
pushing PTT to when you can talk seems long, set
the Power Save Start timer (2nd) in the Expert
screen to “0.000” and set the Tone Start Timing in
the Common 2 screen to 0.600.
➥ In the DTMF Autodial screen, set the 1st Timer to
0.200.
• For PMR:
➥ In the Common 2 screen, set the Tone Start Timing
to 1.100.
➥ In the TX Code CH screen, set CH NO.1 to 1 only.
➥ In the 5Tone setting screen, set the Long Tone Timer
to 0.300.
➥ In the Edit Memory CH screen, set necessary chan-
nel ID's to 1L (click check box to turn the Long Tone
ON). (CCIR 5-tone format)
➥ In the memory CH screen, set necessary channels
to LOG IN (L-IN).
NOTE: At above settings, when the period from
pushing PTT to when you can talk seems long, set
the Power Save Start timer (2nd) in the Expert
screen to 0.000 and set the Tone Start Timing to
0.600.
➥ In the memory CH screen, return necessary
channel ID's to 1 from 1L.
M Other notes
➥ For communication between F300/F400/S series
and F3GT/GS, F4GT/GS series, make sure that the
F3GT/GS, F4GT/GS series power saver settings are
set to the same values as the F300/F400/S series
Tone Start Timing settings.
➥ When using the UT-109/UT-110 for non-rolling type
scrambling there are 32 available scramble codes.
In the memory CH screen, 1 to 255 can be input as
codes however, many of these codes are identical
(adding 32 to a code results in the same scramble
code). The following groups of codes are the same:
1to32
(33 to 64)
(65 to 96)
(97 to 128)
(129 to 160)
(161 to 192)
(193 to 224)
(225 to 255)
➥ When using the UT-110 for rolling type scrambling
similar but different codes will often result in a

different (generally speaking codes that are separated by values of 20 or more will not match).
➥ When using the UT-110 for rolling type scrambling
