Insert radio(s) into desktop charger as shown. 

2.

  Insert round connector of 120-volt adapter into 

jack on back of charger.

in the charging well and the battery pack is charging. After the battery 

pack is fully charged, the charge indicator light will turn

than that. 

To charge a single radio, you can bypass the desktop charger 

and simply insert the wall adapter’s round connector directly 

into the speaker/microphone/charge jack located on the top 

of the radio.
