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.
• Do not store the device in hot places. High temperatures
can shorten the life of the electrical devices, damage the
battery and melt the plastic parts.
