CAUTION!
Possible hearing damage
The device can produce volume levels that may cause temporary or permanent
hearing impairment. Over an extended period of time, even levels that seem to
be uncritical can cause hearing damage.
Decrease the volume level immediately if you experience ringing in your ears or
hearing impairment. If this is not possible, keep a greater distance or use suffi‐
cient ear protectors.

NOTICE!
Power supply
Before connecting the device, ensure that the input voltage (AC outlet) matches
the voltage rating of the device and that the AC outlet is protected by a residual
current circuit breaker. Failure to do so could result in damage to the device and
possibly injure the user.
Unplug the device before electrical storms occur and when it is unused for long
periods of time to reduce the risk of electric shock or fire.
NOTICE!
Risk of fire due to incorrect polarity
Incorrectly inserted batteries may destroy the device or the batteries.
Ensure that proper polarity is observed when inserting batteries.

NOTICE!
Possible damage by leaking batteries
Leaking batteries can cause permanent damage to the device.
Take batteries out of the device if it is not going to be used for a longer period.
NOTICE!
Possible damage due to incorrect storage
Deep discharge can cause batteries to become permanently damaged or lose
some of their capacity.
Before prolonged rest periods, charge the batteries to around 50 % of their
capacity and then switch the equipment off. Store the equipment at a tempera‐
ture between 10 °C and 32 °C in as dry an environment as possible. During
extended storage periods, charge the batteries to 50 % approximately every three
months.
