1.2 Battery
Your SX66 contains a rechargeable Li-ion polymer battery.
Battery power depends on whether you are talking on the
phone, using the PDA, or if the device is on standby.
Battery life estimates:
n Talk-time : 3 - 4 hrs.
n PDA : 15 hrs (approximate.).
n Standby : 168 hrs (approximate.).
n Data retention time : 72 hrs.
The above are based on using one function at a time. Battery
life may vary with switching between functions.
WARNING: To reduce the risk of fire or burns, do not disas-
semble, crush, puncture, short external contacts, heat above
60℃ (140℉), or dispose of in fire or water. Replace only with
manufacturer specified batteries. Recycle or dispose of used
batteries as stipulated by local regulations.
Data retention
It is vital to keep your battery charged. Because your SX66
does not have a hard drive, all data and any new programs
you install are stored in the RAM. If the battery completely
drains, any data or new programs you installed will be
erased. Only the default programs that came with the device
at the time of purchase will remain.
To prevent this kind of data loss, a portion of the main battery
will keep your data safe for 72 hours if your device runs out
of power. An additional battery, the internal backup battery, is
designed to keep your data safe when you remove the main
battery. It will keep the data safe for 20 minutes .
NOTE: Be sure to check that the internal backup battery
power remains at least at 50% OR ABOVE before you re-
move the main battery by tapping the Start menu > Settings
> the System tab > Power .
