Battery Information:
The AA-2104 device is powered by a rechargeable battery. The full performance of a new battery is achieved only after two of three complete charge
and discharge cycles. The battery can be charged and discharged hundreds
of times, but it will eventually wear out. Do not leave a fully charged battery
connected to a charger since overcharging may shorten battery lifetime. If left
unused, a fully charged battery will lose power over time. Leaving the device
in hot or cold places, such as in closed car in summer or winter, will reduce
the capacity and lifetime of the battery. You should always try to keep the battery between 15 ℃ and 25 ℃. Battery performance is particularly limited in
temperatures well below freezing. Do not dispose of batteries in a fire as they
may explode. Batteries may also explode if damaged.
Safety Instructions:
The following suggestions will help you effectively safely use the AA-2104:
Keep the unit away from children.
Maintain equipment dry, rain, moisture and all kinds of liquids or mois-
ture can contain minerals, corrode electronic circuit.
If the device is wet, please make it completely dry.
Do not use or put the devices in dust or dirt storage, it will damage the
detachable parts and electronic components.
Do not use equipment very hot environments, overheating, high tem-
perature will shorten the service life of electronic devices, damage batteries, make some plastic parts deform or melt.
Do not use equipment in very cold environments.
Do not attempt to disassemble the device.
Do not use strong chemicals, detergent or detergent to clean the de-
vice.
Caution:
Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the instructions.
Old electrical appliances must not be disposed of together with the
residual waste, but have to be disposed of separately. The disposal at the
communal collecting point via private persons is for free. The owner of old appliances is responsible to bring the appliances to these collecting points or to
similar collection points. With this little personal effort, you contribute to recycle valuable raw materials and the treatment of toxic substances.
