The turn off sequence, which depends on the condition of the device, can
take 30 seconds. All data that are not saved are lost. All programs are
stopped.
If the procedure does not correct the problem, contact your equipment
administrator.
The backup battery
The SMC-800 devices all have an internal rechargeable backup battery
that provides emergency power to some circuits in the device. The backup
power applies when there is no main battery and when the main battery is
discharged. The purpose is to save the condition of the device.
The backup battery:
• Saves the suspended condition of the device during the battery
replacement, for the time needed to replace the battery.
• Completes the shut down process of the device when the 15 minute
delay without a battery has expired.
• Maintains the internal clock when you store the device without the
battery installed.
Warning
The backup battery is a NiMH battery that the user cannot
replace. An authorized technician must change the battery.
Incorrect installation or programming can cause the battery
to explode.
The backup battery charges automatically when a charged main battery is
installed in the device and you charge the main battery. The backup
battery takes 24 hours to reach a full charge.
Caution
If the backup battery does not have enough charge when you
replace the main battery, you can accidentally reset the
device and erase information.

communication signals from the devices is available.There is no cable
(USB, Ethernet or serial) that connects to the Be.U Mobile. You must use
