• Use your device in temperatures between 0 ºC and 40 ºC, if possible.
Exposing your device to extremely low or high temperatures may result in
damage, malfunction, or even explosion.
Road safety
Check the laws and regulations on the use of devices in the area when you
drive.
• Do not use a hand-held device while driving.
• Give full attention to driving.
• Pull off the road and park before making or answering a call if driving
conditions so require.
• RF energy may affect some electronic systems in your vehicle such as car
stereos and safety equipment.
• When your vehicle is equipped with an air bag, do not obstruct with
installed or portable wireless equipment. It can cause the air bag to fail or
cause serious injury due to improper performance.
• If you are listening to music whilst out and about, please ensure that the
volume is at a reasonable level so that you are aware of your surroundings.
This is of particular importance when near roads.
Avoid damage to your hearing
To prevent possible hearing damage, do not listen at high volume
levels for long periods.
Damage to your hearing can occur if you are exposed to loud sound for long
periods of time. We therefore recommend that you do not turn on or off the
handset close to your ear. We also recommend that music and call volumes
are set to a reasonable level.
• When using headphones, turn the volume down if you cannot hear the
people speaking near you, or if the person sitting next to you can hear
what you are listening to.
• Excessive sound pressure from earphones and headphones can
cause hearing loss.
