Installing the Antenna 

Screw the antenna into the connector at the top of the radio by holding the bottom of the 

antenna and turn it clockwise until secure.

 

 

Install external speaker/MIC 

Open the cover of the jack for external speaker/MIC, and then insert the plug of the external 
speaker or microphone into the jack on the radio. When inserting the accessory plug, make sure 
it is properly aligned (straight) to avoid internal damage to the connector in the radio.
