The charging indicator light will illuminate during charging and typically change color or turn off when fully charged.
- Connecting to Radio: Ensure your two-way radio is turned off. Insert the 2-pin connector of the AR-158 Speaker Microphone firmly into the corresponding audio jack on your radio. Ensure a secure connection to prevent audio issues.
