Analog Input Switching
Alternatively, you may force the
input select
button to select from
among your
analog
inputs on a Linked Mark Levinson preampli-
fier by pressing and holding the button until it shows
DIGITAL
,
then clicking the button to change it to
ANALOG
, and then press-
ing and holding the
input select
button a second time to confirm
your change. (You may change it back at any time by reversing
this procedure.)

BATTERY 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 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.
Conditions that Affect
IR Performance
IR communication between the Remote Control and the Nº37 can be affected by:
• Direct sunlight
• Interior lighting
• Wall, window, ceiling, and floor treatments
• The angle of the Remote Control relative to the Nº37
If the Nº37 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 Nº37 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 Nº37, 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 Nº37 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 Nº37 directly opposite from where you’ll normally operate
the Remote Control. In practice, the Remote Control will operate the Nº37 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.)
