Care and Maintenance
Battery Care
• The device is powered by a rechargeable battery. When the power is weak, please charge the battery. To
extend battery life, use battery power before recharging.
• Unplug the charger from the electrical outlet and the device when not in use. Do not leave the battery
connected to a charger longer than a week. Overloading may shorten its service life.
• Extreme temperatures can affect the battery's carrying capacity. Battery needs adjusting temperature. If the
temperature is above 40 ° C, the battery can not be charged.
• Use the battery only for its purpose. Never use any charger or battery that is damaged.
Do not short - circuit the battery. Accidental short circuit 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). The short circuit may damage the battery or the object that causes it.
• Leaving the battery in hot or cold places, such as in a closed car in summer or in a freezer in the winter, will
reduce the capacity and battery life. Always try to keep the battery between 59 ° F and 77 ° F (15 ° C and 25 °
C). A cold or hot battery may not work temporarily, even when the battery is fully charged.
• Battery performance is particularly limited with sub-zero temperatures.
• Do not dispose of batteries in a fire! Dispose of batteries according to local regulations. Please recycle
whenever possible. Mobile phones are not considered household waste.
Mobile phone maintenance
• Keep the device dry. Precipitation, moisture and all types of liquids or moisture contain minerals that
corrode electronic circuits. If your device gets wet, remove the battery and wait for the device to dry
completely before replacing it.
• Do not use or store the device in dusty, dirty areas. Movable 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 deform 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 apparatus and damage the electronic circuit boards.
• Do not attempt to open the different device according to the instructions in this guide.
• Do not drop, knock or shake the appliance. Rough handling can damage internal circuit boards and fine
mechanics.
• Do not use harsh chemicals, cleaning solvents or strong detergents to clean the device.
• Do not paint the paint device can clog moving parts and prevent proper operation.
