1. DW / EMG Key

This key is used to enable the DW (Dual Watch) function and the EMG (Emergency Channels) function.

DW (Dual Watch)
The DW (Dual Watch) function allows automatic monitoring of two programmable channels. Refer to the following
procedures to enable this function. Select the first channel to monitor using the channel selector knob (6) or the
channel selector keys on the microphone (18, 20). Press the DW key for about 1.5 seconds and the DW icon will
blink on the LCD display. Select now the second channel to monitor, following the same procedure. Finally press the
DW key for about 1.5 seconds and the two programmed channels will be alternately indicated on the LCD display.
Radio will automatically start monitoring (scanning) the two programmed channels. When a signal is detected on one
of the channels, scanning stops and it is possible to listen to communication on that channel. It is possible to transmit
on the channel, by pressing the PTT key (17). If there is no transmission within 5 seconds, radio will start scanning
the two channels again. When the DW function is enabled, the DW icon (F) appears on the LCD display. To exit the
DW function, shortly press the DW key or the PTT key (17).

EMG (Emergency Channels)
Shortly press the DW/EMG key to select the emergency channels. Two emergency channels (CH9, CH19) are pre­programmed according to the selected frequency band (refer to the following table). Each time the key is shortly
pressed, radio selects CH19, then CH9, then the normal operating channel. When an emergency channel is selected
(CH9, CH19), the EMG icon (N) appears on the LCD display.

2. SCAN Key

By pressing the SCAN key, the SCAN (automatic scanning of busy channels) function is enabled. To enable the
SCAN function, first turn the SQUELCH control (10) clockwise, until the background noise is cut. Then press the
SCAN key, radio will automatically start scanning all channels continuously and the SCAN icon (O) will appear on the
LCD. Auto-scan stops if a signal is detected on a channel, in order to let the user listen to the incoming signal and will
start scanning again when no signal is detected on that channel. It is possible to remain on that channel by pressing
the PTT key (17) within 5 seconds, otherwise radio will start scanning again. Auto-scan may be also re-started at any
time by pressing again the SCAN key. To exit the SCAN mode, shortly press the PTT key (17).

3. ESP (Electronic Speech Processor) Key

The ESP (Electronic Speech Processor) is a unique feature available in some INTEK two-way CB radios. ESP means
Electronic Speech Processor, in other words electronic modulation processor. This audio processor is microprocessor
controlled and it is also called COMPANDER (Compressor-Expander). It works as a modulation compressor in transmit
mode and as a modulation expander in receive m ode. The ESP allows to obtain a stronger, clear and clean audio signal
and it is a great help in noisy areas and in case of weak signals or in long distance communication. The efficiency of
ESP is even greater when both stations use this device. The 2nd generation ESP allows to enable only the TX
compressor, only the RX expander or both systems.

To enable or disable the ESP functions, press the ESP key (3), as follows :

1) Press the key once to enable the TX modulation compressor. The ESP C (L) icon will appear on the LCD.

2) Press the key again to enable the RX modulation expander. The ESP E (L) icon will appear on the LCD.

3) Press the key again to enable both the TX modulation compressor and the RX modulation expander.

The ESP C E (L) icon will appear on the LCD.

4) Press the key once again to disable all systems.

4. TX/RX Indicator

This green-red dual colour LED indicator lights up in green colour when radio is in receive mode and in red colour
when radio is in transmit mode.

5. LCD Display

Large size LCD display with an orange colour backlighting system, for best readability. The LCD display shows all the
enabled functions as well as other information programmable by the user, such as the programmed band ID code. It
also includes a digital 10-bar S/RF Meter to monitor the strength/power of the received and transmitted signals.

tampering may cause damage to the product, modify its technical specifications and will void warranty rights. If
service or repair are required, please go to an authorised service centre or specialized technician.

Installation

- 8 -

English

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
(11) knob completely turned counter clockwise at OFF position. The DC power cable (16) 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 adjusted for 27 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 (15), located on the rear side of the radio.

Checking Operation of the Radio

Once radio has been connected to the vehicle electric system and to the antenna, the correct operation of the system
may be checked. Please proceed as follows :

1) Check that the power cable is correctly connected.

2) Check that the RF antenna coaxial cable is correctly connected.

3) Connect the microphone to the connector (12), located on the front side of the radio.

4) Rotate the AS/SQL (10) knob counter clockwise.

5) Turn radio on using the OFF/VOL (11) knob and adjust volume to the desired level.

6) Select the desired channel, using the channel selector knob (6) or the channel selector keys on the microphone
(18, 20).

7) Rotate the AS/SQL (10) knob clockwise, to cut the background noise.

8) Press the PTT (17) key to transmit and release it to receive.

9) Check the level of the received and transmitted signals on the digital bar S/RF Meter (H) on the LCD display.

The transceiver will work correctly.
