Questions & Answers
How do I find the IR sensor on my audio/video components?
Place each emitter on front of the audio/video equipment's infrared
(IR) sensor window. The emitters have double-sided tape to allow you to
fasten them. If your audio/video component has an infrared (IR) remote
control, it will have an IR sensor window, which is typically located on the
front panel. It is usually a small dark or red window and may be labelled
“IR Sensor.” If you cannot locate the IR sensor window, refer to your
audio/video equipment owner's manual. If your owner's manual does not
indicate the location, you can determine the location by repeatedly
covering small areas of your audio/video equipment's front panel with a
piece of cardboard and using your remote control. Hold the cardboard
close to your component and hold your remote control approximately one
foot or more away from (and pointed towards) your component.
Remember, infrared signals are invisible beams of light; a solid object in
the path of the IR signal will prevent your component from seeing the
remote control signals. Once your audio/video equipment is not
responding to the commands from your remote control, you know that
you have covered — and found — the IR sensor window.
How can I maximize the operating range?
Radio system operating range is dependent upon many factors. The
MARC+ Remote Control sends radio signals throughout the house to be
picked up by the MARC+ Receiver. In order to obtain maximum range,
the location of the Receiver is important. In some cases, installing the
Receiver on the second floor will provide greater range than a ground
floor installation. Reception is also affected by atmospheric conditions,
and by metal construction which acts to shield radio signals (for example,
aluminum siding, insulation foil backing, and heating ducts). Of course,
you can't easily relocate your audio/video components to suit MARC+
reception, but you can keep in mind that a higher installation site for your
MARC+ Receiver would be desirable. Also, try to keep the Receiver's
Antenna Wire in a vertical position and away from other cables and metal
cabinets where possible. Alternate antenna systems may help also.
How do I reset my remote control and receiver back to factory settings and clear the
memory?
You can achieve this by removing the batteries from the Remote
Control for about a minute; this resets the Remote Control's Security ID
Code to "1070", and the factory setting X-10® House Code to "A".
For the Receiver, find the small hole in the bottom of the case and
press the recessed pushbutton with a pointed instrument, such as a pen,
holding for approximately one second until the green Data light flashes;
this will erase all of the infrared and Macro codes, as well as reset the Security ID Code
to "1070".
