CAUTION Ensure that you follow the guidelines for battery safety described in

Charging the Main Battery and Memory Backup Battery

Before using the MC75 for the first time, charge the main battery until the amber Charging/Battery Status LED
remains lit (see Table 1-2 on page 1-7
with the appropriate power supply. For information about the accessories available for the MC75, see
Accessories.
The MC75 is equipped with a memory backup battery which automatically charges from the fully-charged main
battery. When using the MC75 for the first time, the backup battery requires approximately 36 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 MC75's main battery is removed. When the MC75 reaches a very low battery state, the combination of main
battery and backup battery retains RAM data in memory for at least 48 hours.
To charge the main battery, use either a charging cable or a cradle. For cable and cradle setup and charging
procedures refer to the MC75 Integrator Guide.
