Battery Care
• Your device is powered by a rechargeable battery. When the power is weak, please charge
the battery. In order to extend the lifespan of the battery, use all the battery's power before
recharging.
• Unplug the charger from the electrical plug and the device when not in use. Do not leave
the battery connected to a charger more than a day. Overcharging may shorten its lifespan.
• Extreme temperatures can affect the ability of your battery to charge. Battery needs the fit
temperature. If the surrounding temperature is over 40°C, the battery cannot be charged.
• Use the battery only for its intended purpose. Never use any charger that is damaged.
Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object
such as a coin, clip, or pen causes direct connection of the positive (+) and negative (-)
terminals of the battery. (These look like metal strips on the battery.) Short-circuiting the
terminals may damage the battery or the connecting object.
• Leaving the phone in hot or cold places, such as in a closed car in summer or a freezer in
winter conditions, will reduce the capacity and lifetime of the battery. Always try to keep the
battery between 59°F and 77°F (15°C and 25°C). A hot or cold battery may not function
temporarily, even when the battery is fully charged.
• Battery performance is particularly limited in temperatures below freezing.
Mobile phone maintenance
Keep the device dry. Precipitation, humidity, and all types of liquids or moisture
can contain minerals that will corrode electronic circuits
Do not use or store the device in dusty, dirty areas. Its moving parts and electronic
components can be damaged.
Do not store the device in hot areas. High temperatures can shorten the life of
electronic devices, damage batteries, and warp or melt certain plastics.
Do not store the device in cold areas. When the device returns to its normal
temperature, moisture can form inside the device and damage electronic circuit
boards.
Do not attempt to open the device other than as instructed in this guide.
Do not drop, knock, or shake the device. Rough handling can break internal circuit
boards and fine mechanics.
Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the
device.
Do not paint the device. Paint can clog the moving parts and prevent proper
operation.
Use only the supplied or an approved replacement antenna. Unauthorized antennas,
modifications, or attachments could damage the device and may violate regulations
governing radio devices.
