Maintaining Your Phone’s Peak Performance
There are several simple guidelines to operating your phone properly
and maintaining safe, satisfactory service.
ⅷ
Hold the phone with the antenna raised, fully-extended, and over
your shoulder.
ⅷ
Try not to hold, bend, or twist the phone’s antenna.
ⅷ
Don’t use the phone if the antenna is damaged.
ⅷ
Speak directly into the mouthpiece.
ⅷ
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.
Note: For the best care of your phone, only Sprint authorized personnel should
service your phone and accessories. Faulty service may void the warranty.
Maintaining Safe Use of and Access to
Your Phone
FAILURE TO FOLLOW THE INSTRUCTIONS OUTLINED MAY LEAD TO
SERIOUS PERSONAL INJURY AND POSSIBLE PROPERTY DAMAGE
Using Your Phone While Driving
Talking on your phone while driving (or operating the phone without a
hands-free device) is prohibited in some jurisdictions. Laws vary as to
specific restrictions. Remember that safety always comes first.
Tip: Purchase an optional hands-free accessory at your local Sprint Store, or call
the Sprint PCS Accessory Hotline
SM
at 1-800-974-2221 or by dialing # 2 2 2 on your
Sprint PCS Phone.

154 Section 4A: Safety
Getting the Most Out of Your Reception
Keeping Tabs on Signal Strength
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; you can also check it yourself
by pressing any key. Anytime the Power Save feature is activated, a
message is displayed on the screen. When a signal is found, your phone
returns to standby mode.
Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver. When it’s
turned on, it receives and transmits radiofrequency (RF) signals. When
you use your phone, the system handling your call controls the power
level. This power can range from 0.006 watts to 0.2 watts in digital
mode.
Knowing Radio Frequency Safety
The design of your Sprint PCS Phone complies with updated NCRP
standards described below.
In 1991-92, the Institute of Electrical and Electronics Engineers (IEEE)
and the American National Standards Institute (ANSI) joined in
updating ANSI’s 1982 standard for safety levels with respect to human
exposure to RF signals. More than 120 scientists, engineers and
physicians from universities, government health agencies and
industries developed this updated standard after reviewing the
available body of research. In 1993, the Federal Communications
Commission (FCC) adopted this updated standard in a regulation. In
August 1996, the FCC adopted hybrid standard consisting of the
existing ANSI/IEEE standard and the guidelines published by the
National Council of Radiation Protection and Measurements (NCRP).
