Receiver Setup and Operation  
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.  
-2-  
 
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.

screwdriver (or other 3/32 - 2.5 mm screwdriver) into the  
adjustment hole opposite the display screen. Turn lightly  
until the screwdriver tip goes into the adjustment level  
control. Gently turn counterclockwise until the control  
stops (the microphone output is at minimum but not off).  
Slowly turn the gain control up (clockwise) while speak-  
ing/singing into the microphone and the audio meter  
shows peaks around -3 dB.  
8. Verify reception. With the transmitter and receiver on and  
matching Group and Channel, the main receiver display  
should be indicating a RF signal on the bar graph. Speak  
into the microphone and the Audio Meter bar graph should  
indicate audio signal presence. If the level meters do not  
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.

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.
