Ensure that the room in which you use this product is wired in accordance with the local electrical code and
checked by a qualified inspector.
•
A correctly earthed mains power connection should always be used.
•
If access to the interior electronics is required, disconnect it from the mains power and allow electrical energy
storage devices, such as capacitors and transformers, to discharge.
•
Other electronic products may generate sufficient heat to require ventilation.
•
Do not block or cover heatsinks, fans, or vents.

Do not expose this product to water, any other liquids, moisture, or naked flames.
•
Do not install this product into hot, humid, or excessively dusty locations, or into direct sunlight.
•
Avoid installing this product into locations where it will experience externally generated vibrations or heat
(e.g. radiators).
•
If the product is moved from a cold environment into a warm one (such as from a vehicle into a building), it is
possible that condensation will form. Please allow the product sufficient time for acclimatization to room
temperature before using.
•
Wherever an amplifier is located, a free flow of air should be maintained by leaving a gap of at least 5 cm (2”)
around it. A flush mounted cabinet with the electronics panel still installed should be well-ventilated to avoid
heat build-up and possible risk of fire.

Loudspeakers are often capable of producing a sound pressure level in excess of 85 dB. This may cause
permanent hearing damage so user caution is recommended. Noise exposure is a function of SPL and time, so
observe local regulations when listening at high levels for a long time. Hearing protection may be required.
