Safety
DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not within reach of babies and young children. Choking
hazard! Ensure that children do not detach any small parts (e.g. knobs or the like) from the unit. They could swallow the pieces and
choke! Never let children unattended use electrical devices.

DANGER!
Electric shock caused by high voltages inside
Within the device there are areas where high voltages may be present. Never remove any covers. There are no user-serviceable parts
inside. Do not use the device if covers, protectors or optical components are missing or damaged.
DANGER!
Electric shock caused by short-circuit
Always use proper ready-made insulated mains cabling (power cord) with a protective contact plug. Do not modify the mains cable
or the plug. Failure to do so could result in electric shock/death or re. If in doubt, seek advice from a registered electrician.
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 sucient ear protectors.
NOTICE!
Risk of re
Do not block areas of ventilation. Do not install the device near any direct heat source. Keep the device away from naked ames.

NOTICE!
Operating conditions
This device has been designed for indoor use only. To prevent damage, never expose the device to any liquid or moisture. Avoid
direct sunlight, heavy dirt, and strong vibrations. Only operate the device within the ambient conditions specied in the chapter
‘Technical specications’ of this user manual. Avoid heavy temperature uctuations and do not switch the device on immediately
after it was exposed to temperature uctuations (for example after transport at low outside temperatures). Dust and dirt inside can
damage the unit. When operated in harmful ambient conditions (dust, smoke, nicotine, fog, etc.), the unit should be maintained by
qualied service personnel at regular intervals to prevent overheating and other malfunction.
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 re.
NOTICE!
Possible damage due to installation of a wrong fuse
The use of dierent types of fuses can cause serious damage to the unit. Fire hazard! Only fuses of the same type may be used.

The plasticiser contained in the rubber feet of this product may possibly react with the coating of your parquet, linoleum, laminate
or PVC oor and after some time cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the oor, but
use felt-pad oor protectors or a carpet.
