OPERATION
When you use the system, a red LED on the front of the 291-00 and the 283M emitter will flash when
receiving your infrared commands.
The maximum usable distance between your IR remote and the 291-00 Receiver will vary for each remote
and might be shorter than when directly used in the room containing the satellite revceiver or other IR
controlled devices.
The 172-94 system
may be left on continuously as it does not affect the normal operation of the remote
controlled device(s) and consumes very little energy.
NOTE: Although the emitters appear dark to the eye, they are transparent to infrared. Positioning them
directly over the infrared window(s) of the component(s) will not block direct IR control from your handheld
remote.
ADVANCED MULTIROOM HOOKUP
Fig. 4 shows an advanced system using two Xtra Links in a multiroom installation. Except for the addition
of a 2-way DC passing RF splitter (such as the Xantech Model 200-00), the connections are essentially the
same. To obtain just the parts needed for the 3rd room, order the 172-94X Xtra Link2 expansion kit. (Note:
The expansion kit
does not include a 2-way DC passing RF splitter. The splitter must be ordered separately).
TROUBLESHOOTING
In some cases, the 291-00 IR Receiver may have to be moved to a different location if the unit is picking
up interference. This interference may, in severe cases, prevent the system from working.
Common sources of interference are:
• RF radiation from the TV set on which the 291-00 IR Receiver may have been placed.
• Direct or reflected sunlight.
• Fluorescent, Compact Fluorescent, Neon, Neon Art, Halogen lights or light dimmers.
• Active Infrared security systems.
You can confirm the source of the interference by temporarily turning off or isolating the 291-00 Receiver
from such sources. Then check to see if the 291-00 operates the satellite receiver or other components.
If the 291-00 still does not work, reposition the Emitters. They may not be located directly over the
component’s infrared receiving sensor. Consult the owner's manual of the unit or the manufacturer for the
exact location of the infrared "window" sensor.
If you have one or more TV sets in rooms where you
do not
have Xtra links and they share the same DC
passing RF splitter, you must use DC Blockers (Xantech Model 203-00) connected in the coaxial line to
each of these TV sets. This is a
must
to prevent such TV sets from "shorting out" the IR control signal.
IMPORTANT: For installations involving more than two remote rooms, use the services of a competent
professional audio/video installer experienced in infrared remote control systems.
