4)
The CTCSS tone number selection does not need to be confirmed. After a CTCSS tone is stored, you may receive and transmit
on the current frequency.
5)
In CTCSS mode, if the LCR key is pressed, the last used frequency will be recalled but it will be associated with the stored
CTCSS tone number.
6)
In CTCSS mode, the DW (Dual Watch) function cannot be used.
7)
To exit the CTCSS mode, press the F key (11) and then the EMG key (14).
FREQUENCY SCAN IN CTCSS MODE
In CTCSS mode, press the SCAN key (7) to start auto scanning of the frequencies associated to the current CTCSS tone. To stop
scanning, shortly press the SCAN key (7) or the PTT key (27).
PROGRAMMING MEMORY FREQUENCIES (M1-M4) WITH AN ASSOCIATED CTCSS TONE
A different CTCSS tone may be associated to a different frequency, by storing it in one of the four memory frequencies (M1-M4).
1) Set the desired frequency and CTCSS tone, as above indicated.
2)
Press the F key (11) and the F icon (R) will blink on the LCD. Press and keep pressed for about 2 seconds one of the four
memory frequencies keys (M1-M4). The programmed memory icon (i.e. M1) (P) will be showed on the LCD.
3)
To recall the desired memory frequency, press the F key (11) (the F icon (R) will blink on the LCD) and then one of the memory
frequencies keys (M1-M4). The selected frequency (Q), the associated CTCSS tone number (Q) and the recalled memory
frequency (i.e. M1) (P) will appear on the LCD (3).
PROGRAMMING THE TRUCK MEMORY FREQUENCY WITH AN ASSOCIATED CTCSS TONE
To program the special TRUCK memory frequency, associated with a CTCSS tone, proceed as follows :
1) Set the desired frequency and CTCSS tone, as above indicated.
2) Press and keep pressed for about 2 seconds the TRUCK key (10). The TRUCK icon (D) icon will be showed on the LCD.
3) The TRUCK memory frequency now is programmed and may be selected by simply pressing the TRUCK key (D). The selected
frequency (Q), the associated CTCSS tone number (Q) and the TRUCK icon (D) will appear on the LCD (3).
Installation
Before installing the main unit in the vehicle, check and select the most convenient location, in order that the radio will be easy to
reach and comfortable to operate, without disturbing or interfering with the vehicle drive. Use the supplied bracket and hardware to
install the radio. The bracket screws must be well tightened in order not to become loosen with the vehicle vibrations. The car
mounting bracket can be installed over or below the radio and the radio may be inclined as desired according to the specific type of
installation (under dashboard or track cabin roof installation).
Installation of the Main Unit
Before connecting the radio to the vehicle electric system, make sure that radio is switched off, with the OFF/VOL (20) knob
completely turned counter clockwise at OFF position. The DC power cable (26) of the radio is complete with a fuse holder with fuse
located on the red positive (+) wire. Connect the DC power cable to the vehicle electric system, with special attention to respect
correct polarity, even if the radio is protected against polarity inversion. Connect the red wire to the positive (+) pole and the black
wire to the negative (-) pole of the vehicle electric system. Make sure that the wires and terminals are firmly and stably connected, in
order to prevent cables from disconnecting or causing short circuits.
Installation of the Antenna
A specific mobile antenna designed for 28-30 MHz frequency range must be used. The antenna installation must be done by a
specialised technician or service centre. Please pay special attention to carefully install the antenna on the vehicle with perfect
connection to ground. Before connecting the antenna to the radio, it is necessary to check the correct operation of the antenna with
low standing wave ratio (S.W.R.), using adequate instruments. If not, the transmitter circuit of the radio could be damaged. The
antenna must be usually installed on the highest part of the vehicle, free from obstacles and as far away as possible from any source
of electric or electromagnetic noise. The RF antenna coaxial cable must not be damaged or pressed on its way between antenna
and the radio. The correct operation of the antenna and the low standing wave ratio (S.W.R.) must be checked periodically. Connect
the RF antenna coaxial cable to the antenna connector (22), located on the rear side of the radio.
Amateur Radio License
To operate this radio, you must have an Amateur Radio License. It is the user’s responsibility to have the necessary authorization or
license to operate this radio in accordance with the regulations of the country where the radio has to be used.
