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.
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!
Magnetic elds
The device generates strong magnetic elds that can interfere with the function of poorly shielded devices. The strongest magnetic
elds are directly above and below the power amplier. Therefore, never place sensitive devices such as pre-ampliers, radio trans‐
mission systems, or tape decks directly above or below the power amplier. When installing the power amplier into a rack, you
should place it in the lowest position, and further equipment such as pre-ampliers in the highest position.
NOTICE!
Possible staining
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.
