122 Troubleshooting
Shortened
standby time
•The standby time is
related to your network
operator's system
configuration. The same
phone used with different
network operators'
systems will not provide
exactly the same length
of standby time.
If you are located in an area
where signaling is weak,
temporarily shut 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 phone's
battery.
SIM card
error
•SIM card malfunction or
damage.
Take the SIM card to your
network operator for testing.
•SIM card inserted
improperly.
Insert the SIM card properly.
•Debris on the SIM card
contacts.
Use a soft, dry cloth to clean
the SIM card contacts.
