Sony 8000 User Manual

• Always use a damp or antistatic cloth to clean the telephone. Never 

use a dry cloth.

• If the telephone is very dirty, clean it with a diluted neutral cleaner con-

taining surfactants, such as a dish detergent. Afterwards remove all 

traces of the cleaner with a damp cloth (using water only).

• Never use cleaners containing alcohol, cleaners that corrode plastic, or 

abrasive powders.

Check if the key is stuck.

Check whether the "Do not disturb" function is activated on your telephone 

("Do not disturb" appears on the screen Æ page 23). If so, deactivate it.

Check whether your telephone is locked ("Phone locked: Enter Password" 

appears on the screen"). If the phone is locked, enter your PIN to unlock it.

First contact the relevant service personnel. If the service personnel are 

unable to correct the problem, contact Customer Service.
