Care and Maintenance
 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
