Caring for the Battery
Protecting Your Battery
The guidelines listed below help you get the most out of your
battery’s performance.
Use only Sprint PCS-approved batteries and desktop chargers. These
chargers are designed to maximize battery life. Using other batteries or
chargers voids your warranty and may cause damage.
In order to avoid damage, charge the battery only in temperatures that
range from 32º F to 113º F (0º C to 45º C).
Don’t use the battery charger in direct sunlight or in high humidity areas,
such as the bathroom.
Never dispose of the battery by incineration.
Keep the metal contacts on top of the battery clean.
Don’t attempt to disassemble or short-circuit the battery.
The battery may need recharging if it has not been used for a long period
of time.
It’s best to replace the battery when it no longer provides acceptable
performance. It can be recharged hundreds of times before it
needs replacing.
Don’t store the battery in high temperature areas for long periods of time.
It’s best to follow these storage rules:
Less than one month:
4º F to 140º F (-20º C to 60º C)
More than one month:
4º F to 113º F (-20º C to 45º C)
Disposal of Lithium Ion (LiIon) Batteries
For safe disposal options of your LiIon batteries, contact your nearest
Sprint PCS-authorized service center.
Special Note:
Be sure to dispose of your battery properly. In some areas,
the disposal of batteries in household or business trash may be prohibited.
Note:
For safety, do not handle a damaged or leaking LiIon battery.

Turning Off Your Phone Before Flying
Turn off your phone before boarding any aircraft. To prevent possible
interference with aircraft systems, the U.S. Federal Aviation Administration
(FAA) regulations require you to have permission from a crew member to use
your phone while the plane is on the ground. To prevent any risk of
interference, FCC regulations prohibit using your phone while the plane is in
the air.
Turning Off Your Phone in Dangerous Areas
To avoid interfering with blasting operations, turn your phone off when in a
blasting area or in other areas with signs indicating two-way radios should
be turned off. Construction crews often use remote-control RF devices to set
off explosives.
Turn your phone off when you're in any area that has a potentially
explosive atmosphere. Although it's rare, your phone and accessories could
generate sparks. Sparks can cause an explosion or fire, resulting in bodily
injury or even death. These areas are often, but not always, clearly marked.
They include:
Fueling areas such as gas stations.
Below deck on boats.
Fuel or chemical transfer or storage facilities.
Areas where the air contains chemicals or particles such as grain, dust or
metal powders.
Any other area where you would normally be advised to turn off your
vehicle’s engine.
Note:
Never transport or store flammable gas, liquid or explosives in the com-
partment of your vehicle that contains your phone or accessories.
Restricting Children’s Access to Your Phone
Your phone is not a toy. Do not allow children to play with it as they could
hurt themselves and others, damage the phone or make calls that increase
your phone bill.
