7. Handling and maintenance
7.1 Battery
• The device has a rechargeable battery. When the power supply is low,
charge the battery.
• Disconnect the charger from the power outlet and the appliance when
not in use. Do not allow the battery to charge for more than a week, as it
may reduce the battery life.
• Extreme temperatures may also affect the battery. If the ambient
temperature exceeds 40 °C, do not charge the battery.
• Do not use a damaged battery or charger.
• Do not short-circuit the battery. For example, a metallic object such as a
coin, clip or pen may cause a short circuit.
• Do not leave the battery too hot (such as in a car in summer) or too cold
(such as freezing), as it may reduce its service life. Try to store the battery
between 15 °C and 25 °C. A too cold or too hot battery may temporarily
not work, even if it is fully charged.
• Do not throw the battery in a fire. Dispose of the used battery according
to local regulations and recycle if possible.
7.2 Maintain the appliance
• Keep the appliance dry. Precipitation, mist and all other liquids can cause
corrosion in the circuit boards.
• Do not store the product in dusty places, as moving parts and electrical
accessories may be damaged.
