6 BATTERY COMPARTMENT
The two AA batteries used by the Remote Control must be placed inside
the compartment on the back of the remote’s housing (near the bottom).
Carefully remove the battery compartment cover and insert the batteries,
being careful to orient them as indicated inside the battery compartment.
Then replace the cover, clicking it into place.
Conditions that Affect
IR Performance
IR communication between the Remote Control and the CDD can be affected by:
• Direct sunlight
• Interior lighting
• Wall, window, ceiling, and floor treatments
• The angle of the Remote Control relative to the CDD
If the CDD will be subject to direct sunlight, place it no more than 10 feet from
where you’ll normally operate the Remote Control. Where bright sunlight virtually
floods the room, IR communication may be inconsistent.
In a room lighted primarily with incandescent fixtures, place the CDD no more
than 25-30 feet from where you’ll normally operate the Remote Control. In a
room with fluorescent fixtures, this range will be reduced. Where bright fluores-
cent lighting virtually floods the room, IR communication may be inconsistent.
IR, like visible light, reacts differently when it meets different surfaces. Carpeting
and draperies, for example, tend to diffuse (scatter) IR and interfere with its trans-
mission. Glossy or reflective surfaces, such as mirrors and smooth walls, “bounce”
(reflect) IR and won’t interfere with its transmission. When placing the CDD, it’s
important to account for potential IR bounce and diffusion. For example, in a
room with thick carpeting, heavy draperies, and many pieces of furniture, you
may need to place the CDD closer to where you’ll normally operate the Remote
Control than you would in a sparsely furnished room with bare walls and hard-
wood flooring.
If possible, install the CDD directly opposite from where you’ll normally operate
the Remote Control. In practice, the Remote Control will operate the CDD at up
to 30 degrees to either side of this direct line. To either side of this line, success-
ful IR communication will depend on bounce and ambient lighting. (Please refer
to diagram on next page.)
