5. Advanced ClearScan:TM This feature automates the pro-
cess of finding a clear group of inter-modulation free
channels and the clearest channels within those groups.
Place the receiver and antennas where there is a clear line
of sight to the area where the transmitter will be used. Ro-
tate the antennas to separate them by 90 degrees.
1.
ClearScanTM, for Groups: From the main display
screen, push SET once and the Group Number will
flash. While Group is flashing, press and hold SET un-
til ClearScanTM appears, release the set key. When the
scan is completed, the display will show the group
with the most clear channels and the Channel number
will indicate how many clear channels are in that
group. Use the UP/DOWN keys and to view other
groups and press SET to select a group. The Group
will be set and the Channel will start to flash. Select a
channel manually or use ClearScanTM for Channels.
a.
2. Connect the power supply cord to the receiver. Plug the
power supply into an AC outlet. Turn the receiver on and
confirm that it is ON by checking the main display screen.
Caution: Please make sure the AC power supply is the cor-
rect voltage for your local requirements before it is
plugged into the wall.
3. Manual Channel Change. Press the SET button and the
Group number will start to flash. The Up and DOWN but-
tons allow you to scroll through the factory set group.
When the group you desire is displayed, press SET to se-
lect that group and the Channel Number will start flashing.
Scroll to the desired channel and press SET to select. The
numbers will stop flashing and the new group and channel
are installed.
ClearScanTM for Channels: To scan for the clearest
channel in a group, press and hold set while the Chan-
nel is flashing until ClearScanTM appears, release the
SET button. When the scan is complete, the display
will show the clearest available channel. Use
UP/DOWN to scroll through the other available chan-
nels rank from clearest to least clear (but still available
for use, ClearScanTM will not display any channel that
can't be used). Press SET to select the channel.
b.
4. Frequency Assignment (Outside of preset Groups and
Channels), press SET and UP at the same time and the
group and channel will go blank and the Frequency will
start flashing. Use UP/DOWN to scroll in 25 KHz steps to
the desired frequency. Press SET and the frequency will be
selected and stop flashing. Press Set and UP at the same
time to return to group and channel operation. Hint: hold-
ing in the Up or Down key will increase the speed of the
scroll. Just release and press again for fine control
Auto ClearScan:TM This function will find the clear-
est group and channel with the press of just one button.
With nothing flashing, press and hold the SET button
until ClearScan appears on the right side of the screen.
When the scan is complete, the receiver will be set to
the clearest channel in the clearest group.
c.

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.
Now refer ahead to transmitter setup and return to step 9
when that is completed.
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.
9.
6. Change Lock-Out: By pressing and holding the UP and
DOWN arrow keys together for 3 seconds, 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 un-
authorized personnel have access to the receiver.
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.
For set up, make sure the mixer or amplifier input used for
the RE-2 is muted or turned down to a minimum level.
7.
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.

show reception, make sure the channels are matching and
refer to the trouble shooting section.
9. Adjustment of the transmitter audio gain - If necessary
The transmitter audio gain is factory set at the middle of
the range, which should be suitable for most applications.
For loud or soft speakers/singers, a gain adjustment may
be necessary. Have the speaker or singer use the micro-
phone in a normal performance level voice. The Audio
Meter in the main receiver display screen should show
peaks around the -3dB level. If the meter peaks all the way
to the right or well below the -3dB level, adjust the trans-
mitter audio gain.
NOTE: Operating with the transmitter audio gain set as
high as possible (without distortion or peaks all the way to
the right end of the meter) will result in the best perfor-
mance and highest signal to noise ratio.

Transmitter On/Off Lock-Out
There are two On/Off lockout modes available, One Time and
Everytime.
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.
One Time: Cycle the power switch 3 times in under 3 seconds
and On-Loc will be displayed for a second and then return to
normal operation. The power switch alone will no longer turn
the unit off. To turn the unit off, put the power switch in the
off position (On-Loc will be displayed) open the battery door
and press [Set], [Up], or [Down] and the unit will power
down. The next time the unit is powered on, the power switch
will operate normally.
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.
Everytime Use: With the unit on and operating in the normal
mode, press and hold [Set], [Up], and [Down] for 3 seconds.
On-Loc will be displayed and the power switch alone will no
longer turn the unit off. To turn the unit off, put the power
switch in the off position, (On-Loc will be displayed), open
the battery door and press [Set], [Up], or [Down] and the unit
will power down. The next time the unit is powered on, the
On-loc function will still be on. To enable the power switch,
press and hold [Set], [Up], and [Down] for 3 seconds (On-Off
will be displayed).
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.
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.
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.
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.
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.
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.
Receiver and Antenna Placement
Multiple Systems
and Advanced ClearScanTM
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.
(See Section 7).
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.
