Switch off your device before boarding an aircraft. The use of wireless teledevices in an
aircraft may be dangerous to the operation of the aircraft and may be illegal.
Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere. Obey all
posted instructions. Sparks in such areas could cause an explosion or fire resulting in
bodily injury or death. Switch off the device at refueling points such as near gas pumps
at service stations. Observe restrictions in fuel depots, storage, and distribution areas;
chemical plants; or where blasting operations are in progress. Areas with a potentially
explosive atmosphere are often, but not always, clearly marked. They include areas
where you would be advised to turn off your vehicle engine, below deck on boats,
chemical transfer or storage facilities and where the air contains chemicals or particles
such as grain, dust, or metal powders. You should check with the manufacturers of
vehicles using liquefied petroleum gas (such as propane or butane) to determine if this
device can be safely used in their vicinity.
The surface of this device is nickel-free.
Emergency calls
Before making an emergency call, switch the device on, and check for adequate signal
strength. If the screen and keys are locked, slide the lock switch on the side of the device
to unlock them.
Important: This device operates using radio signals, wireless networks, landline
networks, and user-programmed functions. Emergency calls can be made using the
cellular phone.It is not possible to make an emergency call using voice calls over the
internet (internet calls). Connections in all conditions cannot be guaranteed. You should
never rely solely on any wireless device for essential communications like medical
emergencies.

Certification information (SAR)
This mobile device meets guidelines for exposure to radio waves.
Your mobile device is a radio transmitter and receiver. It is designed not to exceed the
limits for exposure to radio waves recommended by international guidelines. These
guidelines were developed by the independent scientific organization ICNIRP and include
safety margins designed to assure the protection of all persons, regardless of age and
health.
The exposure guidelines for mobile devices employ a unit of measurement known as the
Specific Absorption Rate or SAR. The SAR limit stated in the ICNIRP guidelines is 2.0 watts/
kilogram (W/kg) averaged over 10 grams of tissue. Tests for SAR are conducted using
standard operating positions with the device transmitting at its highest certified power
level in all tested frequency bands. The actual SAR level of an operating device can be
below the maximum value because the device is designed to use only the power required
to reach the network. That amount changes depending on a number of factors such as
how close you are to a network base station.
The highest SAR value under the ICNIRP guidelines for use of the device at the ear is 0.80
W/kg .
Use of device accessories may result in different SAR values. SAR values may vary
depending on national reporting and testing requirements and the network band.
