Troubleshooting
The adaptive charger incorporates the following features:
• A universal input power supply
• A constant current rapid charger
• A negative pulse conditioning charger
• A calibration unit
• A USB Type A power output
• A user selectable on or off switch for turning On/Off calibration.
The combination of the features above are unique in a desktop charger. Therefore, operation of the
radio with a battery attached while in the charger is not recommended.
During the calibration process, the battery becomes fully discharged. As a result, the radio may shut
down during calibration mode. During the charging process, radio operation may result in minimally
reduced radio performance and extended battery charge time.
When troubleshooting, always observe the color of the LED.
