source when it is not in use. Do not leave the 
battery connected to a charger for more than a 
week, since overcharging may shorten its life.

• Extreme temperatures will affect the charging 

capacity of your battery: it may require cooling or 
warming first.

• Do not leave the battery in hot or cold places 

because the capacity and lifetime of the battery will 
be reduced. Try to keep the battery at room 
temperature. A phone with a hot or cold battery 
may not work temporarily, even when the battery is 
fully charged. Li-ion batteries are particularly 
affected by temperatures below 0° C (32° F).

• Do not short-circuit the battery. Accidental short-

circuiting can occur when a metallic object like a 
coin, clip or pen causes a direct connection between 
the + and – terminals of the battery (metal strips on 
the battery). For example, do not carry a spare 
battery in a pocket or bag where the battery may 
contact metal objects. Short-circuiting the terminals 
may damage the battery or the object causing the 
short-circuiting.

• Dispose of used batteries in accordance with local 

regulations. Always recycle. Do not dispose of 
batteries in a fire.

Road safety

Your wireless phone gives you the powerful ability to 
communicate by voice, almost anywhere, anytime. But 
an important responsibility accompanies the benefits of 
wireless phones, one that every user must uphold.
When you are driving a car, driving is your first 
responsibility. When using your wireless phone while 
driving, follow local regulations in the country or region 
you are in.

Operating environment

Remember to follow any special regulations in force in 
the area you are in, and always switch off your phone 
whenever it is forbidden to use it, or when it may cause 
interference or danger.
