Receiver Setup and Operation
1. 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.
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.
The display will show the company logo, software and
channel map revision levels and then display the main
screen with the last channel set.
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. From the main display screen
press the MENU button once. The Channel Change screen
is now displayed. Press SET: the group number should be
flashing. The Up and DOWN buttons allow you to scroll
through the 10 factory groups and 10 user definable
groups. When the group you desire is displayed, press SET
to select that group and the Channel Number will start
flashing. Scroll to the desired channel, press SET to select.
Pressing MENU anytime before pressing SET negates any
changes made since the last SET. Once the desired group
and channel are displayed (but not flashing) press MENU
twice to return to the main display screen.
4. Frequency Assignment (User Defined Groups Only).
With a User Group* selected in step three, press MENU
once and the frequency assignment screen is displayed.
Press SET and the Frequency Number will flash. Use
UP/DOWN to scroll in 25 kHz steps to the desired fre-
quency. With the desired frequency displayed press SET.
The Channel Number will begin to flash. use the
UP/DOWN keys to select another Channel in this group
you want to assign a frequency, press SET to select and the
Frequency Number will flash. Repeat until all desired
Channels are assigned a frequency. Press MENU to stop ed-
iting. Press MENU twice to return to the main display
screen.
HINT: Holding in the arrow key will increase the speed of
the scroll. Just release and press again for fine control.
* User Defined Groups start at Group #11 and display a "u"
after the group number.
5. Advanced ClearScanTM :This feature automates the pro-
cess of finding a clear group of inter-modulation free
channels and the clearest channels within those groups. To
use ClearScanTM, from the main display screen push Menu
twice (or 3 times if a user defined group is being used) to
go to the Options Screen. Use the UP/DOWN keys and
SET to select the version of ClearScanTM, you wish to run.
a. ClearScanTM All. This program scans all of the groups
(factory and user) and returns a list of groups ranked by
the number of free channels. Once ClearScanTM All has
run, the screen will display the clearest group with the
open channels in that group. You can scroll through the
other ranked groups using UP/DOWN. When you have the
group you want, press SET to run ClearScanTM on that
group. The display will now show the group with the
Channels ranked by clearness. You can scroll through the
channels with UP/DOWN, once the desired channel is
flashing, press SET to select and the display will go to the
main display.
NOTE: Groups 7, 8, 9, and 10 have 16 channels and are
marked with an N (7N). These groups require the transmitters
to be in the NORMAL transmit power setting to work to-
gether. The N groups will always be displayed after groups
1-6 and any user defined groups no matter how many channels
are free. If you need to use more than 12 systems at one time,
scroll down to the N groups and use the clearest group with
Normal transmit power.
b. ClearScanTM Group XX. This program will scan the
group currently selected, which is useful for multi-system
setup. With ClearScanTM All run for the first unit of a
multi-system installation, the clearest group has been se-
lected. For each system added, leave all previously se-
lected channel transmitters on, using Step 3 select the
current group, select ClearScanTM Group and press SET.
The display will show the group and ranked remaining
clear channels. Select the desired channel with UP/DOWN
or simply press SET for the first channel. The channel will
be selected and return to the main display. Repeat until all
systems are set up or all clear channels are full.
c. ClearScanTM Band. This program selects and ranks the
clearest 16 frequencies in the 24 MHz bandwidth regard-
less of groups, channels or previous coordination. This
feature is useful for selecting one clear channel in a very
dirty RF environment. From the Options screen, select
ClearScanTM Band and press SET, this scan will run until
SET is pressed again so it can be used to evaluate a site
over an hour, day or even a week. The program displays
Group 21S with the clearest open frequencies in the band
assigned channels (up to 16). These frequencies will re-
main assigned to this group until ClearScanTM Band is run
again.
Caution: Unlike the factory assigned groups, the channels
in 21S are not coordinated. If more than one channel from
group 21S is used, the combination must be walk tested
with all transmitters on before use.

6. Change Lock-Out. By pressing and holding the UP and
DOWN arrow keys together for 3 seconds, the SET key is
disabled. The MENU button still allows different screens
to be displayed but no settings can be changed and
ClearScanTM will not run. To reactivate the SET key sim-
ply 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 other system input used
for the CSR-1000 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 CSR-1000.
a. NOTE: The XLR connector is the preferred con-
nection since the output is balanced and will be
more immune to noise for longer runs of cable al-
though 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 instrument. 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 sec-
tion.
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. Walk Test the expected area of use to check for coverage.
The SOUND CHECK screen is designed to aid this test.
From the main display screen, press MENU twice (3 times
in user groups) to display the options screen. Scroll down
to Sound Check and press set. This Sound Check Screen
will be displayed:
a. The peak hold audio meter allows you to set the
transmitter gain as high as possible for the appli-
cation which maximizes the signal to noise ratio.
Sing, yell or play the instrument at the loudest de-
sired volume and adjust the gain on the meter.
b. The squelch break counter will tell you if you
are pushing the range or may have some interfer-
ence problems to contend with. Ideally this count
would be zero for the desired performance area.
If there are several squelch breaks while walking
the area, adjust antenna placement or squelch as
in step 11 and retest. Pressing [UP] will turn on
an audible tone that will sound each time the
count is incremented. This tone can be sent to the
monitors or PA so the tester can hear when a drop
occurs and mark the location on the stage.
Pressing [DOWN] turns the tone off.
c. The high/low RF meter will tell you if you have
adequate coverage in the performance area. If the
RF level drops significantly during a walk of the
desired area, reposition the antennas, adjust the
squelch or change the channel and retest.
CAUTION: MUTE OR TURN DOWN THE MIXER OR
AUDIO AMPLIFIERS ETC. BEFORE ADJUSTING THE
SQUELCH. OPEN (MINIMUM) SQUELCH CAN RE-
SULT IN LOUD WHITE NOISE OVER THE AUDIO
SYSTEM.
11. Squelch Adjustment - The squelch setting can be used to
maximize range or immunity to noise. Turn the transmitter
off and from the receiver Options screen select Squelch
Adjustment and press SET. The current squelch setting
will be displayed, the setting bar will flash and "Tones
Off" will be displayed (the tone coded portion of the
squelch must be off in order to notice any changes in the
amplitude squelch setting). Adjust the squelch using the
UP/DOWN keys and walk test the unit. Maximum squelch
(all the way right) maximizes noise immunity but limits
the range. Minimum squelch (all the way left) will maxi-
mize the range but allow more noise to break through the
squelch.

number will flash and can be changed with the UP/DOWN
keys. Once the desired group number is showing, press
SET to select and the Channel number will flash. Select
the Channel and press SET again, the flashing will stop
and the channel is now set.
4. Change Lock-Out. By pressing and holding the UP and
DOWN arrow keys together for 5 seconds, the SET key is
disabled. The MENU button still allows different screens to
be displayed. To reactivate the SET key, simply press and
hold the UP and DOWN keys again for 5 seconds.
5. 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.
6. Adjustment of the transmitter audio gain - If necessary
The transmitter audio gain is factory set at 1/3 of maxi-
mum range, which should be suitable for most applica-
tions. For loud or soft speakers/singers a gain adjustment
may be necessary. Have the speaker or singer use the mi-
crophone 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.
To adjust the transmitter gain, gently insert the provided
screwdriver (or other 3/32 in. screwdriver) into the adjust-
ment 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 speaking/singing
into the microphone and the audio meter shows peaks
around -3 dB.
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 performance and high-
est signal to noise ratio.
7. Transmitting Power Adjustment (if necessary). The
CSH-1000 transmitter has two radio transmit power set-
tings. It is factory set in the NORM position, which will
maximize the number of simultaneous users and limit in-
terference with other wireless devices. Switching to HIGH
power will maximize range for outdoor and single user ap-
plications.
8. Interchangeable Microphone Head. To remove the head,
grasp the handheld transmitter body in one hand and the
ballscreen assembly in the other. Turn the ballscreen coun-
ter clockwise and unscrew until the head is detached. See

ClearScanTM All
ClearScanTM All searches all defined frequency groups for the
ones with the greatest number of receiver channels clear of in-
terference. Once a group is selected an additional scan is made
to determine the best frequencies in the group:
Press [SET] to initiate
Press [MENU] to abort
After scanning, ClearScanTM will display the group that has
the most interference free receive channels. These clear chan-
nels are displayed on the right half of the screen. Busy chan-
nels are represented by an X. Press [SET] to place the receiver
on this group. ClearScanTM then scans to select the clearest
channels within the group (see ClearScanTM Current Group).
Press [SET] to accept this channel and return to the operating
screen.
The [UP] and [DOWN] buttons may be used to select the next
best group/channel and so forth.
Press [MENU] to return to the Operating Screen with the re-
ceiver set to the Group, Channel and Frequency it was on
prior to executing ClearScanTM.

ClearScanTM Current Group
ClearScanTM Current Group scans channels within the cur-
rently selected frequency group and displays the channels that
are clear of interference.
Press [SET] to initiate
Press [MENU] to abort
After scanning the currently selected group, ClearScanTM will
display the channels that are free of interference. These clear
channels are displayed on the right half of the screen. The
channels are ranked according to noise; the channel with the
least amount of interference is presented first.
The [UP] and [DOWN] buttons may be used to select a differ-
ent clear channel within the currently selected group.
Press [SET] to place the receiver on the currently selected
channel and return to the Operating Screen.
Press [MENU] to return to the Operating Screen with the re-
ceiver set to the Group, Channel and Frequency it was on
prior to executing ClearScanTM.
ClearScanTM Band
ClearScanTM band continuously scans all frequencies within
the bandwidth of the receiver. The scan is started at the fre-
quency the receiver is on and proceeds in 200 kHz increments
on either side until the whole band is scanned. The scan is re-
peated until ended by the user.
Press [SET] to initiate
Each frequency is scanned continuously within the band; the
highest reading on each frequency is stored to give a
worse-case reading as long as the scan is being done.
Pressing [SET] ends the scan. After scanning, ClearScanTM
places the 16 best frequencies in the band into 'scanned' group
21s. This group is stored to prevent accidental erasure. The
best frequency is placed at channel one and displayed.
The [UP] and [DOWN] buttons may be used to select the next
clear channel at least 200 kHz above or below the currently
displayed frequency.
Press [SET] to accept currently selected frequency and return
to the Operating Screen.
Press [MENU] to return to the Operating Screen with the re-
ceiver set to the Group, Channel and Frequency it was on
prior to executing ClearScanTM.
