Shortened
standby
time
The standby time is
related to your service
provider system
configuration. The same
phone used with
different service
providers’ systems will
not provide exactly the
same length of standby
time.
If you are located
in an area where
signal is weak,
temporarily switch
off the phone.
The battery is depleted.
In high temperature
environments, battery
life will be shortened.
Use a new battery.
If you are not able to
connect to the network,
the phone will continue
to send out signals as it
attempts to locate a base
station. Doing so
consumes battery power
and will consequently
shorten standby time.
Change your
location to one
where the network
is accessible, or
temporarily turn
off your phone.
You cannot
switch your
phone on.
Battery power has been
depleted.
Recharge the
battery.
