.
Charging the Main Battery and Memory Backup Battery
Before using the FR6874 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
for charge status indications). To charge the FR6874, use a cable or a cradle
with the appropriate power supply. For information about the accessories available for the FR6874, see
Chapter 6,
Accessories
.
The FR6874 is equipped with a memory backup battery which automatically charges from the fully-charged main
battery. When using the FR6874 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 FR6874's main battery is removed. When the FR6874 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
FR6874 Integrator Guide
