10 On/Off

•
Make a general visual inspection for misuse, corrosion or oxidation from liquid damage
according to point 1.2
10.1

Battery

•
Insert a working battery and connect a working charger to the phone. If the battery voltage
is too low the phone will charge the battery without turning on the phone (this will usually
take less than 10 minutes) and when the battery voltage is high enough the phone will be
able to turn on and show charging in the LCD.
If the fault still occurs, try to update the phone to the latest available software version. If this
doesn't solve the problem, handle the unit according to the local directives.
10.2

On/Off key

•
Insert a fully charged battery and turn the phone on. If it fails;
•
Check if the button key (Fig. 10.1) is mechanical damaged or dirty. Replace it if
necessary.
•
Check if the key flex sheet (Fig. 10.2) is mechanical damaged, dirty or oxidized. Replace
it if necessary.
•
Check if the key FPC (Fig. 10.3) is mechanical damaged, dirty or oxidized. Replace it if
necessary.
•
Check if the keyboard flex-film is fitting correct into the FPC connector (Fig. 10.5) and
check if the FPC connector is closed.
If the fault still occurs, try to update the phone to the latest available software version. If this
doesn't solve the problem, handle the unit according to the local directives.
