Over time, you may notice rainbow-like rings forming on the
screen. These rings are only cosmetic and will not impede the
functioning of your product.
Keep the product away from strong magnetic fields (e.g.
loudspeakers) and sources of static electricity.
If you will not be using the product for a while, store it in
a place that is dry, free from damp, dust and extreme
heat and cold. As a matter of precaution, make a back-up
of your files before you store your product.
Antenna Care and Replacement
To avoid impaired performance please ensure your smartphone's
antenna is not bent or damaged.
Do not remove the antenna yourself. If your phone's antenna is
damaged please take it to an Authorized Service Partner.
Only use an antenna that has been specifically designed for your
phone. Unauthorised antennas, modifications, or attachments could
damage the phone and may violate the appropriate regulations
causing loss of performance and radio frequency (RF) energy above
the recommended limits.
Efficient Operation
To enjoy optimum performance with minimum power consumption
please:
Hold the phone as you would any other telephone. While speaking
directly into the mouthpiece, angle the antenna in a direction up and
over your shoulder.
Do not hold the antenna when the phone is in use. Holding the
antenna affects call quality, may cause the phone to operate at a
higher power level than needed and shorten talk and standby times.
Never direct the infrared ray at anyone's eye and make sure that it
does not disturb any other infrared units.
When using the Office Speaker function, it is recommended that your
smartphone is placed on a desktop, at a distance of at least an arm´s
length away. As with any loudspeaker, serious ear problems can be
caused by loud noises too close to your ears.
