To charge the main battery:
1. Connect the charging accessory to the appropriate power source.
2. Insert the MC55 into a cradle or attach to a cable. The MC55 begins charging. The Charging/Battery Status
LED blinks amber while charging, then turns solid amber when fully charged. See Table 1-1 for charging
indications.
The 2400 mAh battery fully charges in approximately four hours and the 3600 mAh battery fully charges in
approximately six hours.
Charging Spare Batteries
See Chapter 2, Accessories for information on using accessories to change spare batteries.
Charging Temperature
Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). Note that charging is intelligently controlled by
the MC55.
To accomplish this, for small periods of time, the MC55 or accessory alternately enables and disables battery
charging to keep the battery at acceptable temperatures. The MC55 or accessory indicates when charging is
disabled due to abnormal temperatures via its LED. See Table 1-1.
Powering On the MC55
After inserting the battery or when turning the MC55 on for the first time, the splash screen displays for about a
minute as the MC55 boots, then the calibration window appears.
