Guidelines for Safe and Efficient Use 115
• To reduce risk of electric shock, unplug the unit from the power source
before attempting any cleaning. Once unplugged, use a soft cloth lightly
dampened with water for cleaning.
• DANGER - Never alter the AC cord or plug. If the plug will not fit into the
outlet, have a proper outlet installed by a qualified electrician. Improper
connection can result in risk of electric shock.
• Don’t twist the antenna. Excess twisting will damage the antenna.
New Batteries
The battery packaged with your phone is not fully charged. For maximum
battery capacity, use your charger to condition the battery.
Recycling Your Battery
The battery must be disposed of properly. The battery should not be disposed
of in municipal waste. Check local regulations for proper disposal

Battery Use and Care
A rechargeable battery has a long service life if treated properly. A new
battery, or one that has not been used for a long period of time, should be
conditioned before using your phone. Avoid recharging a fully-charged or
almost fully-charged battery. If your phone shuts off due to low battery power,
you should charge the battery within 24 hours for the battery to reach full
capacity.
This phone is powered by a rechargeable Lithium-Ion (Li-Ion) battery pack.
Warning! This battery may explode and cause potential injury if exposed to
or disposed of in a fire.
• Do Not expose the battery to temperatures above 140° F (60°C), such as in
a car parked in the usn or on a hot day.
• Do Not short-circuit the battery’s metal contacts with metallic objects,
such as keys in your pocket, as it may damage the battery.
• Do Not disassemble the battery.
• Use only Ericsson Original accessory chargers (including handsfree units
that act as a charger) and the AC/DC adapter supplied with your battery
charger. Use on a non-Ericsson Original accessory may be hazardous and
damage from such use will void your phone warranty.
• Charging the battery at room temperatures below 41°F (5°C) or above
113°F (45°C) may degrade battery performance and could be hazardous.
