Calibrating Batteries
The MH-22 quick charger is equipped with a battery calibration
feature.
Calibrate the battery as required to ensure the accuracy of
the camera and charger battery level displays.
If the calibration lamp for the current
battery chamber blinks when a
battery is inserted, the battery needs
to be calibrated.
To begin
calibration, press the calibration
button for the current chamber for
about a second.
The time needed to
calibrate the battery is shown by the
charge and calibration lamps:
When calibration is complete, the calibration and charge lamps will
turn off and charging will begin immediately.
Although calibration is recommended for accurate measurement
of battery charge state, calibration need not be performed when
the calibration lamp blinks.
Once begun, calibration can be
interrupted as desired.
• If the calibration button is not pressed while the calibration lamp
is blinking, normal charging will begin after about ten seconds.
• To interrupt calibration, press the calibration button again.
Calibration will end and charging will begin.
