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. 

 

Unless otherwise stated, this product is designed to be used indoors only. 

 

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.
