Intended use
Safety instructions

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 staining
The plasticiser contained in the rubber feet of this product may possibly react with the coating of your surface and after some time
cause permanent dark stains. In case of doubt, do not put the rubber feet directly on the surface and use a suitable underlay if neces‐
sary, i.e. felt pads or similar.
