Troubleshooting
The IMPRES 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.

using the USB cable connected to a comput-
er Charging Downstream Port (CDP). The
USB cable is too long or rated current is
below 1.5 A.
What to do...
Check that the battery is inserted correctly.
Make sure that the power supply plug is secure-
ly plugged into the charger and an appropriate
AC outlet, and there is power to the outlet.
Remove the battery from the charger and re-
place it back into the charger.
• Verify that the battery is a Motorola Solu-
tions-authorized battery listed in
Solutions Authorized Batteries on page
Other batteries may not charge.
• Remove power from the battery charger and
using a clean dry cloth, clean the gold metal
charging contacts of both the battery and the
charger.
• Replace battery.
Replace with a shorter 1.5 A rated USB cable
or allow sufficient time for the radio to charge
up to a level where the Battery Charging LED
indicator returns to normal.
