NOTE: Groups x,x,x, and x are set up to work with the
other US frequency band (A and B). These groups are
listed last no matter how many open channels are avail--
able. If you are using a mix of Band A and Band B, scroll
down to these groups and use the clearest group.
6. Change Lock-Out: By pressing and holding the UP and
DOWN arrow keys together for 3seconds, the SET key is
disabled.To reactivate the SET key, simply press and hold
the UP and DOWN keys again for 3seconds. This feature
can be useful when the receiver is in a location where un--
authorized personnel have access to the receiver.
7. For set up, make sure the mixer or amplifier input used for
the RE-2 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 RE-2.
a. NOTE: The XLR connector is the preferred connec--
tion since the output is balanced and will be more im--
mune 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 (midway 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 microphone 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 pres--
ent, 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 approximates the level of an equiva--
lent wired microphone/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 current squelch setting will be dis--
played. Adjust the squelch using the UP/DOWN keys.
Maximum squelch (9) maximizes noise immunity but lim--
its the range. Minimum squelch (1) will maximize the range
but allow more noise to break through the squelch. Press
SET to save the new squelch setting.

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 channel in order to work
together. The RE-2 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 RE-2 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 RE-2 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 as--
sistance if you are planning more systems or using the RE-2
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 frequencies. The smaller the
preset group, the more compatible the frequencies are.
Multiple Systems
and Advanced ClearScanTM
Because all of the channels in the factory set groups are com--
patible, Advanced ClearScanTM can be used to set up multiple
systems quickly and with confidence. When setting up more
than one system, set up the first system using the ClearScanTM
All function.
Once the working Group has been established, leave the first
transmitter on, set the next receiver Group to the working
Group and run ClearScanTM Group. This will provide the next
clearest channel 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 choos--
ing 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 digital signal processors
(reverb/multi-effects units), electronic keyboards, digital
lighting controllers, 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 devices to minimize potential
problems.
Analog and Digital Television stations can also interfere with
your wireless system. The RE-2 is designed to operate over 24
MHz of RF bandwidth, which covers four TV channels. The
factory presets on the RE-2 are optimized for conditions
where one or possibly two of the four stations are covered in
your area. If three of the four stations are used in your area, it
will severely limit the number of systems that will operate to--
gether and you should be using a different band.
Battery Recommendations
Fresh 9-volt alkaline batteries form a quality manufacturer
will yield the best performance from your RE-2 transmitters.
Rechargeable 8.4-volt Ni-Cad batteries can be used but will
result in much shorter operation 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 battery is weak or dead. If the light
comes on during use, the battery is weakening and should be
replaced as soon as possible. If sound quality degrades 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 bat--
teries. Use of other battery types will result in false read--
ings on these indicators although the battery low LED on
the transmitters 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. Ideally, 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 re--
sults with multiple receivers, use an APD4 antenna splitter.

transmitter
Bodypack or Handheld transmitter
will not turn off, display says On-Loc
Possible Causes
Receiver is too close to digital signal
processor or similar device
Strong electromagnetic field from
stage lighting or other source near the
transmitter or receiver, which may be
producing RF noise at or near the op--
erating frequency
RF reflective metal obstacles between
the transmitter and receiver

Solutions
Move the receiver to a different
location
Use ClearScanTM to change the operat--
ing frequency. Repair or remove the
source of interference. Move the re--
ceiver to a different location.
Move the obstacles, or reposition the
receiver/antennas
Check the antenna connection and re--
orient the bodypack so the antenna is
vertical (up and down) and facing the
receiver, if possible.
Check all antenna connections and re--
position to be in line-of-sight with the
transmitter
Disable lock out (see pages 3 and 8)
