Technical Notes-Specifications If the Calibration Lamp Blinks If the calibration lamp blinks for about ten seconds after a battery is inserted, the battery needs to be calibrated to ensure that its charge state can be ac- curately measured. The time needed to calibrate the battery is shown by the charge lamps: Approximate time Calibration needed to recalibrate lamp (yellow) battery CAL ON Charge lamps (green) 2 h 4 h 6 h Over 6 hours Glows Glows Glows Glows 4 - 6 hours Glows Glows Glows Off 2 - 4 hours Glows Glows Off Off Under 2 hours Glows Off Off Off To start calibration, press the CAL button next to the calibration lamp for about a second while the lamp is blinking. When calibration is complete, the calibration and charge lamps will turn off and charging will begin. 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 CAL button is not pressed while the calibration lamp is blinking, nor- mal charging will begin after about ten seconds. • To interrupt calibration, press the calibration button again. Calibration will end and charging will begin. Troubleshooting • If the lamps blink when no battery is inserted: the MH-21 has malfunctioned. Unplug the charger immediately and contact a Nikon service representative. • If the calibration and charge lamps all flash at once when a battery is inserted: a problem occurred during charging. Remove the battery and unplug the charger immediately, then contact a Nikon service representative. 267
