Charging the Battery
Charging the Main Battery
Before using the MC55 for the first time, charge the main battery until the amber Charging/Battery Status LED
remains lit (see Table 1-1 on page 1-6 for charge status indications). To charge the MC55, use a cable or a cradle
with the appropriate power supply. For information about the accessories available for the MC55, see Chapter 2,
Accessories.
The MC55A0 is equipped with a memory backup battery which automatically charges from the fully-charged main
battery. When using the MC55A0 for the first time, the backup battery requires approximately 40 hours to fully
charge. This is also true any time the backup battery is discharged, which occurs when the main battery is
removed for several hours. The backup battery retains RAM data in memory for at least 15 minutes (at room
temperature) when the MC55A0’s main battery is removed. When the MC55A0 reaches a very low battery state,
the combination of main battery and backup battery retains RAM data in memory for at least 48 hours.
For cable and cradle setup and charging procedures see Chapter 2, Accessories for more information.
