INSTALLATION
If you are installing the MS120 into an existing wall,
take time to consider any possible obstructions
which may be hidden inside the wall, such as wood
or metal studs; electrical, telephone or other types
of wiring; plumbing; AC or heating conduits; old
wall safes; etc.
1.DetermineamountinglocationfortheMS120.
Select a location where you will have access
to the rear of the MS120 after it is installed.
This will allow you to securely tighten the
MS120 to the mounting surface using the
supplied hardware.

3.RuntheMS120’sIRcable.Labelthecablefor
future reference. The MS120 is supplied with
10’ofpre-strippedIRcable.TheIRcablemay
be shortened or lengthened as needed. If you
wanttomaketheMS120’scableshorter,usea
pair of wire cutters to cut the cable to the
desired length. The IR cable may be lengthened
by splicing it to a recommended IR cable (See
InstallationConsiderations—TypeofCable).You
may splice the MS120 cable to another cable by
soldering or crimping the connections.

OPERATION
Operation of the MS120 is straightforward. Simply
aim your hand-held remote at the MS120. Your
IR command is instantly repeated to your A/V
equipment.
TROUBLESHOOTING
This manual contains instructions for the MS120
only. For specific information on the adjustment
and operation of your Niles infrared extender
system, please refer to the instruction manual
included with your Niles IR main system unit
(MSU140, MSU250, MSU480 MSU440Z).
1. Test the remote control(s) by operating the
A/Vequipmentdirectly.Replacethebatteries
if needed.
2.Doublecheckthecableconnectionsonthe
MS120 and on the main system unit. Look for
open, shorted or reversed wires.
3.Testforinterferencefromthefollowing
sources:
•Neon,CompactFlorescentLighting(CFL),or
halogen lights in the room
•Lightdimmers,beginningwiththoseclosest
to the MS120
Observe the main system unit IR confirmation
LED while performing all the tests. It is possible
to have interference from more than one source.
Eliminating Optical Feedback
In some installations, two conditions combine to
create an optical feedback loop. Symptoms can
include: poor range, intermittent operation or no
operation.
The conditions which sometimes combine to
create a feedback loop are:
1. Both a sensor and a flasher are located within
the same room.
2. There is some low-level noise or interference
on your system.
You can eliminate optical feedback by replacing
any IRB1 “flooding flasher” with an MF1 or MF2
MicroFlasher
®
and covering all flashers with the
supplied IR blocking covers.
EMI (Electromagnetic Interference)
Identify the source of the interference. The most
common sources of electromagnetic interference
are listed in the Installation Considerations
section. To eliminate EMI try the following
methods:
1. Move the sensor or the sensor cable away
from the EMI source or move the source of
the EMI away from the sensor or the cable.
2.ConnecttheSensor’sGNDterminaltotrue
earthground(ifthisisn’tfeasibleusethe
mainsystemunit’sGNDterminal).
There are many methods for reducing
interference. Which solution is best for you
depends on your situation. If you require further
assistance call Niles Technical Support at
305-238-4373 or 1-800-289-4434
(M-F 8:00 AM - 7:00PM ET).
