Sony CM-Z100SPR - Manual (Page 34)

The design of your Sprint PCS Phone complies with these updated
standards. Of course, if you want to limit RF exposure even further
than the updated standard, you can choose to control the duration of
your calls and operate your phone in the most power-efficient manner.
Maintaining your phone’s peak performance.
To operate your phone properly — that is, to maintain safe and
satisfactory service — you should follow these rules:
For best reception, extend the antenna fully.
Hold the phone with the antenna up and over your shoulder.
Do not hold the phone antenna at any time.
Do not use the phone with a damaged antenna.
Speak directly into the mouthpiece.
To prevent fire or shock hazard, do not expose your phone or
accessories to rain or moisture. If your phone does get wet,
turn the power off immediately and remove the battery pack. If it is
inoperable, return it to a Sprint PCS Center or call Sprint PCS
Customer Care for service.

Protecting your battery.
Follow these guidelines for the best battery performance:
Only use approved battery packs and desktop and travel chargers.
These chargers are designed to maximize battery life. Using other
batteries or chargers will void your warranty and may cause
damage as well.
To avoid damage, charge the battery only in temperatures ranging
from 40°F to 104°F.
Do not use the battery charger in direct sunlight or in high
humidity areas, such as the bathroom.
Never dispose of the battery pack by burning.
Keep the metal contacts at the top of the battery pack clean.
Do not allow the battery contacts to touch metal materials.
Do not attempt to disassemble or short-circuit the battery pack.
You may need to recharge the battery if it has not been used for
a long time.
Replace the battery when it no longer provides acceptable
performance. It can be recharged hundreds of times before
it will need to be replaced.
