Charging Spare Batteries

See Chapter 5, Accessories

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

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 initializes its flash file system, then the calibration window appears. Note that these
windows also appear upon cold boot.
