roubleshooting

The battery drains 
faster than normal.

•  Are you in an area of variable coverage? This 

uses extra battery power.

•  Is your antenna fully extended and correctly 

angled? Do you have a clear unobstructed 
view of the sky? This helps use less battery 
power.

•  Is it a new battery? A new battery needs two 

to three charge/discharge cycles to attain 
normal performance

•  Is it an old battery? Battery performance 

declines after several years of use. Replace 
the battery.

•  Is it a battery that hasn’t been completely 

discharged? Allow the battery to fully 
discharge (until the phone turns itself off) 
and then charge the battery overnight.

•  Are you using your phone in extreme 

temperatures? At extreme hot or cold 
temperatures, battery performance is 
significantly reduced.

You find your phone 
becoming warm 
during use.

You may notice this during long calls or 
during charging. The heat is produced by the 
electronic components within your phone and 
is quite normal.

Phone is not 
responding to user 
controls including 
the power keys.

Remove the battery from the phone and then 
reattach it to cycle power and reset.

Your SIM card is 
inserted in the phone 
but the display says: 

Check Card or 
Insert Card or 
Blocked

Check that the SIM card has been inserted 
correctly. The contacts of the SIM card may be 
dirty. Turn the phone off, remove the SIM card 
and rub the contacts with a clean cloth. Replace 
the card in the phone.

Enter the PIN unblocking key or contact your 
service provider. See “Call Barring PIN” on page 
163 for additional information.
