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 Radiofrequency Safety

The design of your Sprint PCS Vision 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).

Maintaining Your Phone’s Peak Performance

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 mouthpiece.

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.
