Charging

Charging of an internal battery takes about four hours. Remove battery from receiver
and place battery(s) in charger bay(s), plug charger into AC adapter, and then plug AC
adapter into 100-240VAC, 3-prong AC source. The status lights on the charger
indicate the following:
• Yellow—Standby
• Red—Charging
• Green—Charged
• Blinking Red - Error
The charger and battery communicate capacity and charge level information. The charger will
terminate the charge cycle when the calculated charge time has expired to protect the battery from
being over-charged. The battery memory and the actual charge state of the battery do not match.
The battery needs to be calibrated.

Calibration

The battery circuitry stores and communicates charge capacity and charge level
information. The accuracy of the charge level indicator relative to the actual charge
level of the battery will degrade over time. The charger supports the ability to calibrate
the battery to the actual charge level. Calibration is a three-step process. The first
