Conditions that Affect IR Performance
intensity/•standby: Pressing this button momentarily cycles the Nº31.5 (and any Linked Mark Levinson components) through their four levels of display intensity (bright, medium, dim, off). When pressed and held for about one second (denoted by the bold dot •), this button will place the Nº31.5 into or out of standby. If you continue to hold this button after the Nº31.5 en- ters standby, it will force the entire Linked system into standby. This function is available even when the Nº31.5 is already in standby, in which case its display will activate long enough to confirm your command visually.
7BATTERY COMPARTMENT
The two AA batteries used by the Remote Control must be placed inside the compartment at the bottom of the remote’s housing. Using the 5⁄64" hex wrench provided in your accessory kit (look inside the slot within the foam rubber), carefully remove the two screws on the bottom of the housing and insert the batteries, being careful to orient them as indicated inside the bat- tery compartment. Then replace the screws using the hex wrench.
IR communication between the Remote Control and the Nº31.5 can be affected by:
•Direct sunlight
•Interior lighting
•Wall, window, ceiling, and floor treatments
•The angle of the Remote Control relative to the Nº31.5
If the Nº31.5 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 Nº31.5 no more than
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 Nº31.5, it is 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 Nº31.5 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 Nº31.5 directly opposite from where you’ll normally operate the Remote Control. In practice, the Remote Control will operate the Nº31.5 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.)
