PECIFICATIONS
IR System
Compatible with virtually all brands of
remotes using carrier frequencies between
26 and 60 kHz
IR Transmitting Range
18 to 30 feet if mounted so that the transmit-
ting L.E.D.'s face the sensors in a direct line
of sight.
IR Transmitting Angle
Variable with the brand and/or model of the
audio/video component. Because of the
high power and “flooding” pattern of the
IRC-1, extreme transmitting angles can be
successfully used if the sensor window of
the component is close.
Unit Dimensions
1" Wide x 2" High x 3/4" Deep (Includes
Velcro)
Mounting
Supplied with self-adhesive tape attached
to Velcro strips
Wiring Requirements
Supplied with 10 feet of 2-conductor 22
gauge connecting wire. Substitute an 18
gauge 2-conductor wire for distances rang-
ing from 10 to 20 feet and a 16 gauge
2-conductor wire for up to 200 feet.
the Flasher Level Adjust (located on the
Main System Unit) counter-clockwise.
2.
Replace the IRC-1 with an IRC-2 for each
component controlled by the problem-
causing flasher. The IRC-2 comes with a
plastic IR blocking cover which will pre-
vent the IR output of the flasher from reach-
ing the sensor in the same room.
If problems persist, refer to the user's
manual for the Main System Unit or con-
tact your local Niles dealer.
it is farther away from the sensor win-
dow or off to the side of the sensor win-
dow. If adjusting the level down makes
no change, or makes operation even
worse, return the level to the full power
position (clockwise). Then,
try moving the
IRC-1 closer to the sensor window or try to
point the L.E.D.'s more directly at the sensor
window.
Optical IR Feedback Loop
If there is an IR sensor and an IR flasher
located within the same room—an "optical
IR feedback loop" can occur. This occurs
when the IR output from a flasher uninten-
tionally reaches an IR sensor located with-
in the same room. The IR commands are
eventually forwarded back to the IR flasher
and the whole process endlessly repeats
itself. This effect is similar to acoustical
feedback (the howling or whistling sound
heard in a P.A. system when the micro-
phone is placed too close to the speaker).
The optical IR feedback loop can be elimi-
nated by one of the two following methods.
1. Reduce the flasher output until normal
operation resumes. This is done by turning

ROUBLESHOOTING
This troubleshooting guide discusses the
most common problems that prevent an IR
flasher from operating correctly.
Testing the Remote Control
Test that the hand-held remote control
operates the component when you point
it at the front panel (check the batteries if
it does not).
Main System Unit Power Supply
Check that the red power light on the
Main System Unit is lit (the wall adapter
should be plugged into an active AC
wall outlet and the wall adapter has to
be supplying 12V DC).
Adjusting the Flasher Level
Try adjusting the flasher level up or
down (some components sensors are
overloaded by too strong a command
from the IRC-1). If the operation of the
component improves when the flasher
level is all the way down, but it is still
not perfect, try moving the IRC-1 so that
Mounting the IRC-1
Test the operation of the IRC-1 in the
planned mounting location. If all of the
components operate correctly via the IR
repeater system, mount the IRC-1 using it’s
self-adhesive Velcro strip. Make sure the
mounting surface is clean and dry. Remove
the protective coating from the back of the
Velcro strip attached to the IRC-1 and stick
it in place. Coil any excess connecting wire
and tie it in place.
tem. Consult the operating manual of the
Niles main system unit or consult your
local Niles dealer for more information.
Increasing the Wire Length
If the connecting wire is too short to reach
the main system unit, a new length of heav-
ier gauge wire should be spliced onto a six
inch length of the original wire. For dis-
tances between ten and twenty feet
upgrade the original wire to an eighteen
gauge two-conductor wire. For distances
of up to two hundred feet go to a sixteen
gauge two-conductor wire.

TECH TIP
Wire size is
expressed by its
AWG (American
Wire Gauge) num-
ber. The lower the
number, the larger
the wire, i.e. twelve
AWG is physically
larger than fourteen
