Cautions
Changes or modifications made in the radio phone, not
expressly approved by Samsung, will void the user’s
authority to operate the equipment.
Only use approved batteries, antennas and chargers. The
use of any unauthorized accessories may be dangerous
and void the phone warranty if said accessories cause
damage or a defect to the phone.
Although your phone 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 phone
or install the phone in a vehicle. Faulty installation or
service may be dangerous and may invalidate any
warranty applicable to the device.
• Check regularly that all wireless phone equipment in
your vehicle is mounted and operating properly.
• Do not store or carry flammable liquids, gases or
explosive materials in the same compartment as the
phone, 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 both installed or portable wireless equipment
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 off your phone before boarding an aircraft. It
is dangerous and illegal to use wireless phones in an
aircraft because they can interfere with the operation
of the aircraft.
• Failure to observe these instructions may lead to the
suspension or denial of telephone services to the
offender, or legal action, or both.

Product Performance
Getting the Most Out of Your Signal Reception
The quality of each call you make or receive depends on
the signal strength in your area. Your phone informs you
of the current signal strength by displaying a number
of bars next to the signal strength icon. The more bars
displayed, the stronger the signal.
If you’re inside a building, being near a window may give
you better reception.
Understanding the Power Save Feature
If your phone is unable to find a signal after 15 minutes of
searching, a Power Save feature is automatically activated.
If your phone is active, it periodically rechecks service
availability or you can check it yourself by pressing any
key.
Anytime the Power Save feature is activated, a message
displays on the screen. When a signal is found, your
phone returns to standby mode.
Maintaining Your Phone’s Peak Performance
For the best care of your phone, only authorized personnel
should service your phone and accessories. Faulty service
may void the warranty.
There are several simple guidelines to operating your
phone properly and maintaining safe, satisfactory
service.
• Hold the phone with the antenna raised, fully-extended
and over your shoulder.
• Try not to hold, bend or twist the phone’s antenna.
• Don’t use the phone if the antenna is damaged.
• Speak directly into the phone’s receiver.
• Avoid exposing your phone and accessories to rain or
liquid spills. If your phone does get wet, immediately
turn the power off and remove the battery. If it is
inoperable, call Customer Care for service.
