6. Change Lock-Out: By pressing and holding the
UP and DOWN arrow keys together for 3 sec--
onds, the SET key is disabled.To reactivate the
SET key, simply press and hold the UP and
DOWN keys again for 3 seconds. This feature
can be useful when the receiver is in a location
where unauthorized personnel have access to
the receiver.
7. For set up, make sure the mixer or amplifier in--
put used for the FMR-500 is muted or turned
down to a minimum level.
8. Plug an audio cable (not supplied) into the 3 pin
XLR or 1/4 inch output of the FMR-500.
a. NOTE: The XLR connector is the pre--
ferred connection since the output is bal--
anced and will be more immune to noise
for longer runs of cable although either
can be used with good results. If the 1/4
inch connector is used, adjust the output
level on the back panel to 12 o'clock (mid--
way in the range) to start and adjust later if
necessary.
Now refer ahead to transmitter setup and return
to step 9 when that is completed.
9. With the transmitter on, speak into the micro--
phone or play the guitar. Turn up the level on
the mixer or amplifier until you are able to hear
the desired signal. If no audio is present, repeat
setup and refer to the troubleshooting section.
NOTE: If the 1/4 inch output is used, it may be
necessary to adjust the receiver output until the
volume level from the wireless system approxi--
mates the level of an equivalent wired micro--
phone/instrument.
10. Squelch Adjustment - The squelch setting can
be used to maximize range or immunity to
noise. Press and hold Up for 3 seconds. The cur--
rent squelch setting will be displayed. Adjust
the squelch using the UP/DOWN keys. Maxi--
mum squelch (9) maximizes noise immunity but
limits the range. Minimum squelch (1) will maxi--
mize the range but allow more noise to break
through the squelch. Press SET to save the new
squelch setting.

Rack Mount Installation
The FMR-500 is supplied with rack mounts for sin--
gle and double mounting in a standard EIA 19"/
483mm equipment rack (see Figure 3). For rack
mounting a single unit, a long (#3) and short (#1)
"ear" are used. For dual side-by-side mounting, use
the short (#1) "ears" and the mid brackets (#2) from
two FMR-500's as shown.
To assemble the rack mount adapters to the
FMR-500 proceed as follows:
1. Remove the front Phillips head screws from
each side of each unit.
2. Align the correct rack ear or bracket with the
holes on the side of the unit. Install the previ--
ously removed screws. Insert an additional
screw (#2, provided in the parts pack) into the
remaining hole. Repeat this step for the opposite
side of the unit. Be sure to tighten all screws se--
curely.
Front Mounting Antennas
1. Remove hole plugs from brackets.
2. Attach the antenna connectors to the brackets.
Four double mounting of two FMR-500's proceed
as follows:
1. Align the mid brackets (#2) with the holes on
the adjacent sides of each unit.
2. Install the previously removed screws. Insert an
additional screw (#4, provided in the parts pack)
into the remaining holes. Tighten all screws se--
curely.
3. Place the two assemblies side-by-side with the
mid brackets together. (The left bracket should
fit above the right so that the countersinks are
visible). Install 4 flat head screws (#5, provided
in the parts pack) and tighten them securely.
3. Attach the supplied extension cables from the
rack connectors to the antenna connections on
the back of the receiver. See Figure 4.

Guidelines and Recommendations
for Best Performance
Compatibility
The transmitter and receiver must be of the same
frequency band and set to the same group and chan--
nel in order to work together. The FMR-500 is
available in two frequency bands, A and B. The
band information is available in the Group/Channel
edit screen on the receiver, the bottom label on the
handheld transmitter, and on the back panel label on
the bodypack.
Using Multiple Wireless Systems
If two or more FMR-500 systems and/or other
UHF/VHF wireless systems are being used in the
same location, proper frequency coordination is
necessary to avoid interference. All channels in the
FMR-500 factory set groups are designed to work
together, so if channels from just one group are used
no further coordination is required. Contact your
dealer or Telex for assistance if you are planning
more systems or using the FMR-500 with other
wireless equipment.
IMPORTANT NOTE: Always use the
smallest preset group that meets your
needs. For instance, if you want to set up
6 units, use one of the groups of 8 fre--
quencies. The smaller the preset group,
the more compatible the frequencies are.
Multiple Systems
and Advanced ClearScan
Because all of the channels in the factory set groups
are compatible, Advanced ClearScan can be used to
set up multiple systems quickly and with confi--
dence. When setting up more than one system, set
up the first system using the Auto-ClearScanTM
function.
Once the working Group has been established,
leave the first transmitter on, set the next receiver
Group to the working Group and run ClearScan for
Channels. This will provide the next clearest chan--
nel in that group. Set the transmitter to match, leave
it on and repeat until all the systems are set up. If
you run out of clear channels in one group but need
to set up more systems, contact your dealer or Telex
for assistance in choosing additional frequencies.
Potential Sources of Interference
There are many potential sources of interference for
your wireless system. Any electronic product
that contains digital circuitry including digi--
tal signal processors (reverb/multi-effects
units), electronic keyboards, digital lighting control--
lers, CD and DVD players, and computers, all emit
RF energy that can adversely affect the performance
of your wireless system. It is always best to place
the receiver as far away as possible from these de--
vices to minimize potential problems.
Analog and Digital Television stations can also in--
terfere with your wireless system. The FMR-500 is
designed to operate over 28 MHz of RF bandwidth,
which covers six TV channels. The factory presets
on the FMR-500 are optimized for conditions where
one, two, or possibly three of the six stations are
covered in your area. If four or more of the six sta--
tions are used in your area, it will severely limit the
number of systems that will operate together and
you should be using a different band.
Battery Recommendations
Fresh 9-volt alkaline batteries form a quality manu--
facturer will yield the best performance from your
transmitters. Rechargeable 8.4-volt Ni-Cad batteries
can be used but will result in much shorter opera--
tion time.
When the transmitters are turned on, the red battery
LED will flash once if the battery is good. If the
light does not light or stays lit continuously, the bat--
tery is weak or dead. If the light comes on during
use, the battery is weakening and should be re--
placed as soon as possible. If sound quality de--
grades during use, it may be the result of a
weakening battery.
Caution: The battery level indicators, on the
transmitters and receiver displays, are based on
the use of alkaline batteries. Use of other battery
types will result in false readings on these indica--
tors although the battery low LED on the trans--
mitters will operate normally.
Receiver and Antenna Placement
Do not place the receiver near a large metal object
or surface. Locate the receiver as close as possible
to the area where the transmitter will be used. Ide--
ally, position the receiver/antennas within sight of
the transmitter. When using multiple systems, do
not allow antennas to cross or touch each other. For
best results with multiple receivers, use a UAD-2
antenna splitter. (See Section 7).
