use only. The permissible ambient 
temperature is 15-35 degrees Celsius (50-
95°F) and permissible relative humidity 
between 20% and 80%. Humidity 
condensation on the product is not 
allowed during use. For instance, if the 
product has been stored or transported 
in a cool environment and then taken into 
a warm room, it must be allowed to warm 
up to the ambient temperature before 
connecting to mains power. 

Mounting Considerations

Place the monitor so that its acoustic axes 
are aimed towards the listening position 
(see Figures 1 and 2). Place monitors 
with left-right symmetry and at an equal 
distance from the listening position. 
Acoustic reflections from objects close 
to monitors and the listening position 
can cause colouration and blurring of the 
sound image. Symmetrical positioning of 
reflective objects maintains good stereo 
imaging. When soffit (flush) mounting, the 
wall surface should extend to the monitor, 
forming a continuous surface.
