6. Basic and Maintenance
6.1 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 week. 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 or battery 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 battery 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.
• Do not dispose of batteries in a fire! Dispose of batteries according to local regulations. Please
recycle when possible. Cellphones are not considered household waste.
6.2 Smart Phone Maintenance
• Keep the device dry. Precipitation, humidity, and all types of liquids or moisture can contain
minerals that will corrode electronic circuits. If your device does get wet, remove the battery and
allow the device to dry completely before replacing it.
• 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.
