Tro u b l es h o ot i n g Q An echo can be heard during connection with a certain telephone in a certain area. A It is called 'Echo Phenomenon'. It occurs if the volume is too high or caused by special properties (semi electronic telephone exchange) of the machine on the other end. Q The phone gets warm. A During long calls, or if games/Internet are used for a long time, the phone may become hot. This is perfectly normal and has no effect upon the life of the product or performance. Q The bell does not ring, or lamp or LCD blinks only. A The phone is set to 'Vibrate' or 'Silent' in the Profiles menu. Please select 'General' or 'outdoor' Q Usage time of battery becomes shorter. A If the battery time is short, it may be due to the user environment, or large volume of calls, or weak signals. Q No number is dialled when you recall a phonebook entry. A Check that the numbers have been saved correctly, by using the phonebook Search feature. Resave them, if necessary. Q You cannot be contacted. A Is your phone switched on ( pressed for more than three seconds)? Are you accessing the right cellular network? Have you set an incoming call barring option? Q Standby duration of the phone gradually becomes shorter. A Batteries have a limited life. When the battery lasts for half its original time, it requires replacement. Only use authorised replacement parts. Q I cannot find the lock, PIN, or PUK code, or password? A The default lock code is '0000'. If you forget or lose the lock code, contact your phone dealer. If you forget or lose a PIN or PUK code, or if you have not received such a code, contact your network service provider. 103
