7 Programming frequencies and
CTCSS/DCS codes
7. Programming modes
You can redefine radio frequencies (choosing them among the eight
PMR446 frequencies mentioned in par.5.5.a) factory set for each one
of the 16 channels and allocate to each one a CTCSS tone or DCS
code. For further details on the PMR446 frequencies and CTCSS/
DCS consult par. 5.7 and the tables in chapter 11.
To enter programming mode do the following:
1) Turn off the transceiver.
2) Keep the PTT and SCAN/MON buttons pressed and turn the
device back on. All symbols on the display light up for about one
second and a beep sound of confirmation is heard.
3) When the display comes back to its normal status, release the
buttons. The display will show the icon to signal that you
are in programming mode.
To exit programming mode (and stores the new settings) press the
PTT button or turn the device off and then turn it back on.
WARNING! It is advisable to leave the first eight channels
unchanged so as to keep maximum compatibility with devices of
other manufactures which are normally set in the same way.
7.1.a Setting of radio frequencies and of CTCSS/DCS
1) Go into programming mode as described above (the display show
). On the left you will be able to read the flashing number
of the channel and on the right the (smaller) number equal to the
radio frequency programmed according to the following table:
Num. FREQUENCY (MHz) Num. FREQUENCY (MHz)
 446.00625 5 446.05625
2 446.01875 6 446.06875
3 446.03125 7 446.08125
4 446.04375 8 446.09375
E.g..  3 = channel  programmed with radio frequency 3
(446.03125 MHz)
2) Press the + or – button to select the channel to program (from 1
to 16).
3) Press the MENU button. The smaller number corresponding to
the current radio frequency flashes on the right.
4) If you wish to change the radio frequency press the + or – button
until you have reached the desired frequency.
5) At this point:
• If no more changing are required go to step 2).
• If you wish to change the frequency of another channel press
twice the MENU button and repeat operation from step 2.
• If you wish to programme/change CTCSS tone or DCS code
of the currently selected channel carry on with the following
step.
6) According to the predefined setting of currently tuned channel, on
the right the display shows:
• coF or doF - channel is not set with CTCSS or DCS (open
traffic)
• c followed by number XX - the channel has been programmed
with a CTCSS tone with number XX
• d followed by number XX - the channel has been programmed
with DCS code number XX
7) Press the + or – button to choose desired setting. There are 38
