Although your mobile device is quite sturdy, it is a complex piece of equipment and can be broken.
Avoid dropping, hitting, bending, or sitting on it.
Other Important Safety Information
• Only qualified personnel should service the mobile device or install the mobile device in a vehicle.
Faulty installation or service may be dangerous and may invalidate any warranty applicable to
the device.
• Ensure that any mobile devices or related equipment installed in your vehicle are securely mounted.
• Check regularly that all wireless mobile device equipment in your vehicle is mounted and
operating properly.
• When using a headset in dry environments, static electricity can build up in the headset and cause
a small quick static electrical shock. To minimize the risk of electrostatic discharge from the headset
avoid using the headset in extremely dry environments or touch a grounded unpainted metal object
to discharge static electricity before inserting the headset.
• Do not store or carry flammable liquids, gases, or explosive materials in the same compartment as
the mobile device, its parts, or accessories.
• For vehicles equipped with an air bag, remember that an air bag inflates with great force. Do not
place objects, including installed or portable wireless equipment near or in the area over the air bag
or in the air bag deployment area. If wireless equipment is improperly installed and the air bag
inflates, serious injury could result.
• Switch your mobile device off before boarding an aircraft. The use of wireless mobile devices in
aircraft is illegal and may be dangerous to the aircraft’s operation. Check with appropriate
authorities before using any function of a mobile device while on an aircraft.
• Failure to observe these instructions may lead to the suspension or denial of cell phone services to
the offender, or legal action, or both.
• While using your device, leave some lights on in the room and do not hold the screen too close to
your eyes.
• Seizures or blackouts can occur when you are exposed to flashing lights while watching videos or
playing games for extended periods. If you feel any discomfort, stop using the device immediately.
• Reduce risk of repetitive motion injuries. When you repetitively perform actions, such as pressing
keys, drawing characters on a touch screen with your fingers, or playing games, you may
experience occasional discomfort in your hands, neck, shoulders, or other parts of your body. When
using your device for extended periods, hold the device with a relaxed grip, press the keys lightly,
and take frequent breaks. If you continue to have discomfort during or after such use, stop use and
see a physician.
• If your device has a camera flash or light, do not use the flash or light close to the eyes of people
or pets. [122011]
