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 (21), located on the front side of the radio. 

4)   Rotate the AS/SQL (19) knob counter clockwise. 
5)   Turn radio on using the OFF/VOL (20) knob and adjust volume to the desired level. 
6)   Set the desired frequency, using the CHANNEL selector (13) or the frequency selector keys on the microphone (28 and 30). 

7)   Rotate the AS/SQL (19) knob clockwise, to cut the background noise. 
8)   Press the PTT (27) 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 (L) on the LCD display. 
The transceiver will work correctly.
