Aerial Care
• Do not cover the top of the phone (p. 8, No. 21) with your
hand when in use as this may interfere with the performance
of the built-in aerial. Call quality may deteriorate leading to
shortened talk-time and standby time because the mobile
phone has to operate on a higher power level than is
necessary.
• Use only the aerial supplied or one approved by Sharp for
your mobile phone. Using unauthorised or modified aerials
may damage the mobile phone. Moreover, since the mobile
phone may violate the appropriate regulations, it may lose
performance or exceed the limitation of SAR levels.
• To avoid impaired performance, do not damage the aerial of
the mobile phone.
• While talking directly to the microphone, please hold the
mobile phone so that the aerial is upwards over your
shoulder.
• To avoid interfering with blasting operations, please turn off
the mobile phone in a blasting area or in a place where a
"turn off two-way radio" sign is posted.
Camera Operation
• Learn picture quality, file formats, etc. beforehand.
The taken pictures can be saved in JPEG format.
• Be careful not to move your hand while taking pictures.
If the phone moves while taking a picture, the picture can
become blurred. When taking a picture, hold the phone
firmly to prevent it from moving, or use the delay timer.
• Clean the lens cover before taking a picture.
Fingerprints, oils, etc. on the lens cover hinder clear
focusing. Wipe them off with a soft cloth before taking a
picture.
Others
• As with any electronic storage unit, data may be lost or
corrupted under various circumstances.
• Before connecting the phone with a PC or a peripheral unit,
read the operation manual for the other unit carefully.
• If the phone's battery has been removed for some time, or
the phone has been reset, the unit's clock and calendar may
be reinitialised. The date and time should be updated in this
case.
