Control & Operation
Front Panel
1. AM/FM Selector This key allows the user to select the AM or FM operating mode in both RX and TX. The AM/FM operating mode selection is possible only if it is enabled on the programmed frequency band. 2. CH9/CH19 Selector This key allows quick access to one of the two pre-programmed emergency channels (CH9 and CH19). Each time this key is pressed, the radio will select CH9, then CH19, then again the normal operating channel. When one of the emergency channels is selected, EMG will appear on the LED display. The operating mode (AM or FM) for the emergency channels is factory pre-programmed. 3. TX Indicator This red LED indicator lights up when the radio is in transmit mode. 4. FM Indicator This green LED indicator lights up when the radio is in FM mode. 5. LED Display The large two-digit LED display indicates the operating channel and the programmed frequency band code. 6. DN (Down) Key This key allows selection of the operating channel in decrements. By keeping this key pressed, the quick channel selection mode will be enabled. 7. UP (Up) Key This key allows the selection of the operating channel in increments. By keeping this key pressed, the quick channel selection mode will be enabled. 8. SQUELCH Control The SQUELCH control allows the operator to silence the radio, blocking the background noise, when no signals are received on the operating channel. Turn the SQUELCH knob clockwise until the background noise stops. Turn the SQUELCH knob counterclockwise (SQUELCH opening) to listen to the weakest signals. If this switch is turned off the Automatic Squlech Control will be activated. Page 4 of 14

9. OFF / VOLUME Control Use this knob to switch the radio ON and OFF, as well as to adjust the receiver volume to the desired level. To adjust the receiver volume (if no signals are received on the operating channel), open the SQUELCH and then adjust the receiver volume using the background noise as a reference. 10. Microphone Connector Insert the microphone lead to this connector and turn the connector ring in a clockwise to lock it. Rear
11. EXT (External) Speaker Jack This jack is for connecting an (optional) external speaker. 12. ANTENNA Connector Please refer to the section ANTENNA INSTALLATION (page 6). 13. 13.2VDC POWER CORD Microphone

Installation
Before installing the main unit in a vehicle, identify the most convenient location, so that the radio will be easy to reach and comfortable to operate, without disturbing or interfering with driving the vehicle. Use the supplied bracket and hardware to install the radio. The bracket screws must be well tightened to prevent loosening with the vehicle vibrations. The car mounting bracket can be installed over or below the radio and the radio may be tilted as desired according to the specific type of installation (under dashboard or track cabin roof installation).
Installation of Main Unit
Before connecting the radio to the vehicles electricity supply, ensure the radio is switched off, with the OFF/VOLUME knob completely turned counter clockwise at the OFF position. The DC power cable of the radio is complete with a fuse holder with the fuse located on the red positive (+) wire. Connect the DC power cable to the vehicles electricity supply, pay special attention with respect to 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 vehicles electricity supply. 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 Antenna
A specific mobile antenna adjusted for 27 MHz frequency range must be used. The antenna installation must be carried out by a specialist 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 appropriate instruments. If not, the transmitter circuit of the radio could be damaged. The antenna must be 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, located on the rear side of the radio.

Operational Test
Once radio has been connected to the vehicles electricity supply 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 (located on the front side of the radio). 4) Rotate the SQUELCH knob counter clockwise. 5) Turn radio on using the OFF/VOLUME knob and adjust volume to the desired level. 6) Select the desired channel, using the channel selector keys. 7) Rotate the SQUELCH knob clockwise, to cut the background noise. 8) Press the PTT key to transmit and release it to receive. If this check is successful the transceiver will work correctly.
Frequency Bands Table
The CM10 transceiver includes an advanced multi-standard programmable circuit, which allows programming on different frequency bands, specifications and operating modes, in conformity with the regulations in the country where the product is used. 8 programmable frequency bands are available, as per the below table:
COUNTRY CODE 01 02 03 04 05 06 07 08 COUNTRY ITALY / SPAIN ITALY GERMANY GERMANY EUROPE / FRANCE CEPT UK POLAND SPECIFICATIONS (CH, operating modes, TX power) 40CH AM / FM 4W 36CH AM / FM 4W 80CH FM 4W - 12CH AM 1W 40CH FM 4W - 12CH AM 1W 40CH FM 4W - 40CH AM 1W 40CH FM 4W 40CH FM 4W UK FREQUENCIES -40CH FM 4W CEPT FREQUENCIES 40CH AM / FM 4W POLISH FREQUENCIES
Attention! This radio has been factory pre-programmed on the CE frequency band (CEPT 40CH FM 4W), as this standard is currently accepted in all the European countries. Please refer to the information table at page 1 (Restrictions on the use of CB transceivers).
Frequency Band Selection/Programming
This two-way CB radio must be programmed and exclusively used on a frequency band allowed in the country where the product is used. When radio is switched ON, the current programmed frequency band code will be displayed (blinking) for around 3 seconds. To program a different frequency band, proceed as follows: 1) Turn the radio OFF. 2) Press and hold the UP key, then turn the radio ON using the OFF/VOLUME knob. 3) The current frequency band code will blink on the display. 4) Now select the new desired frequency band code by pressing the UP or DN key; during the frequency band selection process, the frequency band display will blink at a faster rate. 5) Press and hold the DN key to confirm and store the new selected frequency band code.
