Health and Safety Information 166
Cautions
Any changes or modifications to your mobile device not
expressly approved by Samsung could void your warranty for
this equipment and void your authority to operate this
equipment. Only use approved batteries, antennas, and
chargers. The use of any unauthorized accessories may be
dangerous and void the mobile device warranty if said
accessories cause damage or a defect to the mobile device.
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.
