attached audio mixer, causing distortion. Conversely, if the output is set too low, the
overall signal-to-noise ratio of the system may be reduced, causing noticeable hiss.
If such noise occurs, adjust the output level of the receiver so that highest sound
pressure level going into the microphone transmitter causes no input overload in
the mixer, but permits the mixer level control to operate in the normal range (not
too high and not too low). This provides the optimal signal-to-noise for the entire
system.

the unit is not to be used for a long period as the transmitters draw a tiny residual
current to maintain the programmed settings, even when turned off. Also, since
batteries installed for a long time can sometimes corrode and/or leak, causing
damage, it is generally recommended that batteries be removed whenever the
transmitters are not being used.

when an electric guitar with dirty pots or connections is used with a wireless system.
Therefore, the supplied capacitor provides first-order filtering of the RF signal from
the cord into the guitar and eliminates virtually all scratchy noises. Should your
equipment still produce scratchy noise, we suggest these steps to eliminate prob-
lems:
1) Make sure all guitar volume and tone pots are clean and all contacts are
solid. This is very important.
2) Solder a 47pF capacitor across the pot to ground terminal of the guitar’s
volume and tone pots to provide extra filtering.

U-800 RECEIVER
Button Function
The POWER ON Button (1) is used to power receiver ON or OFF. When the
power button is pressed, the POWER LED (2) and the white backlight on the LCD
DISPLAY (5) will light up indicating the receiver is ready. Press the Power button
again to turn off the receiver. The power LED and the backlight on the LCD will be off
indicating the receiver is off. At power-off the U-800 receiver will store the last settings
entered and re-display them at power-on. It can be reprogrammed to any new
Group/Channel, or Mute level. The default factory setting is Group 11, Channel 01
and Mute 0 on the first LCD menu screen.
The UP BUTTON (16) is pressed one step at a time to SCAN, IR or to increase
GROUP, CHANNEL, MUTE by one level each time
The DOWN BUTTON (17) is pressed one step at a time to decrease GROUP,
CHANNEL, MUTE by one level each time
The MENU BUTTON (18) is pressed one step at a time for Auto Scan Frequency
or to Automatic GR/CH ASC™ Sync, or if pressed repeatedly the LCD DISPLAY (5)
menu will cycle through the following screens. Press the MENU BUTTON (18) and
the UP BUTTON (16) at the same time to lock or unlock the keyboard/buttons.
During manual programming, press the MENU BUTTON (18) to confirm the selection
and advance to the next menu before the Auto Programming Function takes over
after 5 sec.
Rack Mounting the Receiver
There are 2 options available for rack mounting the U-800 receiver: singly or side
by-side with another U-800 receiver.
a. Single mounting: Remove the receiver SIDE MOUNT CLIP (24) from each
side of the receiver (as shown) and slide in the optional ERM-12 RACK EARS (25).
b. Side-by-side double mounting: After removing the SIDE MOUNT CLIPS (24)
from both U-800 receivers join the two receivers with the EJC-3 JOINING CLIP (26)
and attach the ERM-22 RACK EARS (27) as shown.
(Note: Do not mount the receiver in a rack directly above an amplifier or other source
of high heat — this could degrade the performance of the U-800. Always ensure ad-
equate airflow and heat dissipation in any rack configuration.)
5. SYSTEM OPERATION
17
Feedback
Avoid acoustic feedback (howling or screeching) by taking care in selecting PA
volume, transmitter location and speaker placement.
Please also note the pickup pattern characteristics of the microphone selected.
Unidirectional microphones are more resistant to feedback. However, they pick up
sound sources best that are directly in front of the microphone. Also, mics that are
farther from the sound source (such as a handheld) require more acoustic gain and
thus are also more prone to feedback than close-source mics.
No or Low Audio
If you are not getting audio through the system, carefully re-check all setups.
Especially note that the receiver and transmitter must be set to operate on the same
RF channel. Also confirm that the transmitter’s AUDIO MUTE (36, 40) is not in the
OFF position. The receiver’s UNBALANCED LINE OUT (19) is adjustable so make
sure the VOLUME CONTROL (21) is set properly.
RF Interference and Finding Open Channels
The FCC mandates the following information be provided to all end users of this
equipment:
Consumer Alert
Most users do not need a license to operate this wireless microphone system.
Nevertheless, operating this microphone system without a license is subject to certain
restrictions: the system may not cause harmful interference; it must operate at a low
power level (not in excess of 50mW); and it has no protection from interference
received from any other device. Purchasers should also be aware that the FCC is
currently evaluating use of wireless microphone systems, and these rules are subject
to change.
For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC)
or visit www.fcc.gov/cgb/consumerfacts/wirelessmic_factsheet.html.
If you encounter slight receiving interference when the transmitter is far from the
receiver (from other than an operating TV station on the same frequency), it can
often be overcome by adjusting the receiver‘s MUTE LEVEL/SQUELCH (13)pÃii
Adjusting the Mute Level / RFSquelch.

7. CAUTIONS AND TROUBLESHOOTING
16
Receiver/Transmitter ASC™ IR Sync Manual Programming
To manually program the pre-selected Group/Channel (frequency) from the receiver
to the transmitter, place the transmitter’s IR RECEPTOR SENSOR WINDOW (37,
44) 6-12” away from the receiver’s IR WINDOW (4). Press the MENU BUTTON
(18) four times to the IR Screen Display and then press the UP BUTTON (16) to
start IR programming. The flashing IR INDICATOR (10) icon indicates IR transmission
is in progress. When the synchronization is completed successfully (usually in
less than 2 seconds), the RF INDICATOR (8) and the diversity A or B INDICATOR
(9) on the receiver will display, indicating that the IR linking is completed. The
LCD DISPLAY SCREEN (5) will show the selected channel. If the UP button is not
pressed during the two seconds of active data transfer, the IR INDICATOR (10) will
not flash, the LCD Display will revert to the main menu, the receiver will not link to the
transmitter, and the transmitter’s previously programmed channel remains unchanged.
Instructions for Setup of Simultaneous Multichannel Operation
This U-800 receiver is capable of finding an open channel with its autoscan capability.
This built-in feature is a quick, convenient way to set up many wireless systems at
the same location for simultaneous multichannel operation.
If you are using multiple transmitters at the same location, set up the first transmitter and
leave it ON and keep 10 feet away from the receivers and 1 foot away from transmitter
to transmitter. This avoids possible duplicate selection of the same channel as already se-
lected for the first receiver. Then start the autoscan function on the second receiver. Repeat
this procedure for all receiver/transmitters to be used in your system. Finally with all the
transmitters ON, perform a range walk test in the location these systems will be used in to
check for potential crosstalk interference in this application.
If you are not satisfied with any of the channels scanned, repeat the autoscan procedure
for that receiver again anytime for finding another free channel.
This process can be simplified if you select channels within Factory SELECTED Groups
11 to1A, as the channels within those groups are mutually compatible (unless there is
outside interference on any of the selected frequencies). If there is any such interference in
your location, select as many channels as you can using these 10 groups and
then select additional open channels as needed (depending on number of systems to
be operated simultaneously) from Groups 1B to 1F. As noted above all these groups
will retain in memory the previously selected channels for that group for easy setup
subsequently in that same location.

Powering the Receiver
Plug the AC/DC ADAPTER (23) provided into the DC INPUT JACK (20)
on the back of the receiver. Then plug the power supply into an AC outlet. (Note:
Any 22V DC source with 400mA capability can also be used.) Press the POWER
SWITCH (1) once to turn on the receiver. The POWER ON LED (2) and the LCD
DISPLAY (5) will now light and the receiver is operational.
Adjusting Antennas
The U-800 has two permanently attached, flexible-elbow ANTENNAS (3) for diver-
sityreception. Unfold and rotate these antennas to operate the receiver. The optimal
positions of the antennas are flared 45° out from the receiver sides and 90° from each
other. For maximum range, it is always best to maintain a line-of-sight (no obstructions)
between the receiver antennas and the transmitter at all times whenever possible.
Adjusting the Mute Level/ RF Squelch
The MUTE LEVEL/RF SQUELCH (13) can be changed anytime during the main
screen display to quiet the receiver in high noise environment condition. The control
ranges are from level 0 to level 5. The level should be adjusted to a lower number
for the minimum RF squelch setting at which the RF INDICATOR (8) will remain on
while your transmitter is in normal use, up to the maximum operating range anticipated
in use for your application. However, in areas of high RF activity, the squelch
control may need to be adjusted to a higher number. If the transmitter is off and the
receiver’s signal RF INDICATOR (8) or the diversity A or B INDICATOR (9) flickers
or stays on continuously, the squelch should be adjusted to a higher number to stop
the flickering. Be careful not to select too high a number setting as this may reduce the
operating range to below what is needed. A range walk test will help in selecting the
proper level. If the range is not critical, note that a higher level (maximum
squelch) setting will also yield a quieter mute function, which might be desired in
certain applications. The squelch level is factory preset at maximum sensitivity and
operating range (i.e. level 0 for minimum squelch level—maximum usable range).
Note: For easier intuitive operation, the MIN and MAX indications for this control
refer to the minimum and maximum operating range settings, not to the actual mute
levels selected, which are the opposite as per above.
Keyboard/Buttons Lock Function
Use keyboard/Buttons Lock Function to lock or unlock the receiver controls, preventing
accidental adjustment during use: You can push and hold MENU BUTTON (18),
then push UP BUTTON (16) to lock; push and hold MENU BUTTON (18), then
push UP BUTTON (16) again to unlock. The Keyboard/Buttons must be unlocked
before you can make a selection: AUTO SCAN, Group/Channel or MUTE levels.
10
Audio Level and Peak LED Indicator
The U-800 receiver has a 5 bar AF LCD (7) display that typically shows a few bars
indicating normal level audio signal from the transmitter. Occasional flickering of
the fifth AF LCD (peak level) on loud inputs to the transmitter is normal. If the AF LCD
lights up full bars continuously decrease the input audio level to the transmitter or
overload distortion may result.
Connecting the Audio Output
The U-800 receiver has two type of outputs available, an adjustable level ¼”
UNBALANCED LINE OUT (19) and a fixed level MIC out BALANCED MIC
OUT XLR JACK (22). The ¼” unbalanced line out is controlled by the VOLUME
CONTROL (21).
For unbalanced line output connection, plug an audio cable with a ¼” mono
(Tip/Sleeve) plug into the Unbalanced Line Out jack and plug the other end into your
mixing board or amplifier. Adjusting the Volume control will increase or decrease the
audio level at the ¼” Unbalanced Line Out only.
(Note: When using the UB-800 instrument transmitter system, connect the
Unbalanced Line Out directly to your instrument amp or preamp. At maximum
receiver volume setting, the system output is approximately +4dB higher than a direct
cord-to-amp connection.)
For balanced Output connection, plug an audio cable with an XLR connector into the
Balanced Mic Out XLR Jack socket and plug the other end into your mixing board or
amplifier and control the audio levels from there. Both the ¼” Unbalanced Line Out
and the XLR Balanced Mic Out can be used at the same time to connect to your
mixing board, effect, or amplifier. Please follow below drawing for the audio cable/
connector wiring.
Your U-800 receiver is now operational and ready to use. Proceed to the following
instructions for the UH-800 handheld microphone transmitter or UB-800 bodypack
transmitter included with your system.
Note: As when making any connection, make sure the amplifier or mixing board
volume is at the minimum level before plugging in the receiver to avoid possible sound
system damage.
Note: Only one transmitter can be used with one receiver. It is not possible to use
two transmitters on the same frequency and mix the output of these transmitters into one
wireless receiver.

stored channels for any group, i.e, selecting any group will automatically display the
last channel selected for that group. See section “11. U-800 Frequency Lists”
for available channels in each group. The previous group and channel used is stored
in memory automatically when receiver and transmitter are turned off after operation.
Selecting a different group on the receiver in subsequent use will display a differ-
ent channel as previously selected for that group, however, the transmitter will need
again to be sync’ed to that new frequency to complete the system setup for operation.
Receiver ASC/IR Sync GR/CH (Frequency)
If different frequencies than previously stored in both the receiver and transmitter
memories are needed, there are three ways to program the receiver and then sync

Connecting Input Audio Source
Lapel/Head Mic Uses (UB-800 LT/HM)
The mini 3.5mm locking INPUT JACK (39) is for connecting the audio input from a
lavaliere/lapel Mic (LT), a Head Mic™ (HM), or an instrument (GT) cable, depending
on which transmitter version is being used. Secure the connection to the cable by tighten-
ing the cable mini plug’s outer ring counterclockwise. When ready to play, slide the
AUDIO MUTE ON/OFF SWITCH (40) to the ON position to un-mute the audio.
Adjust the INPUT VOLUME LEVEL (43) on the transmitter for suitable level.
Instrument Use (UB-800 GT)
Secure the connection of the GT (instrument) cable by tightening the mini plug outer
ring counterclockwise onto the 3.5mm locking INPUT JACK (39). When ready
to play, slide the AUDIO MUTE ON/OFF SWITCH (40) to the ON position to
un-mute the audio. Adjust the volume on the receiver for one-to-one unity gain with
a hardwired cord or select up to an added 4-5dB boost by adjusting the receiver
volume to maximum for normal use with guitars and bass guitars.
Note: The audio level should be adjusted on the instrument as when using a hardwired
cord.
Programming the UB-800 to the Selected Group/Channel (frequency)
The transmitter must be programmed to the same frequency as selected for the receiver
via automatic synchronization using the IR ASC™ Sync function. It cannot be pro-
grammed on the transmitter itself. See next section “6. Selecting Group/Channel,
IR Programming and Simultaneous Multichannel Operation”.
Note: Note: The transmitter should be turned ON and ready for the IR communica-
tions with the receiver IR receptor for the following process.
Note: If no button is pressed within the five seconds period during a selection, the
program is terminated and the process needs to be repeated.
Note: For normal operation, the transmitter should have the same channel as dis-
played on the receiver.
Choosing Group/Channel for the System
The receiver offers a choice of 15 groups: 10 that are Factory PRESET (Group 11
to 1A) and 5 that are User SELECTABLE (Group 1B to 1F). If the Factory PRESET
Group mode is chosen, only a limited numbers of channels are available in these
groups. For most convenient setup, each of these groups offers from 3 to 14 channels
(depending on group selected) to choose from that are factory preset for simultaneous
multichannel operation compatibility and are retained in memory after the receiver
is powered off. For the User SELECTABLE Group 1B-1F mode, a letter “U” will lit up
on the LCD DISPLAY (5) instead of the CHANNEL (12) number as in the Factory
PRESET Groups. Each User SELECTABLE Group has 800 channels to choose from
either by manually selecting a channel or using the Auto-Scan in 1MHz segment
increments at a time within the frequency band and they are retained in memory

Programming the U-800 to the Selected Group/Channel (frequency)
The Receiver must be programmed for a Group/Channel (frequency) first then auto-
matic synchronization using the IR ASC™ Sync function to the transmitter. For system
set up procedures, see next section “6. Selecting Group/Channel, IR Pro-
gramming and Simultaneous Multichannel Operation”
UH-800 Handheld Microphone Transmitter (HT)
Setting up the UH-800 Transmitter
The UH-800 requires two AA alkaline or NiMH batteries to operate (do not mix
types). Installing batteries by unscrewing counterclockwise the BATTERY COVER
(29) and slide down, exposing the BATTERY COMPACTMENT (32). Insert two
fresh AA BATTERIES (31), observing the correct polarity as marked, and screw the
cover back on to the microphone. Make sure the cover is screwed clockwise complete-
ly. Fresh alkaline batteries can last up to 10 hours in use, but in order to ensure
optimum performance, it is recommended that you replace the batteries after every
6-8 hours of use.
Powering the UH-800 Transmitter On/Off
Turn on the UH-800 by sliding the AUDIO SWITCH (36) to the OFF position first.
Then slide the POWER SWITCH (35) to the ON position. The POWER ON LED
(33) will stay on, indicating that the transmitter is now on. The BATTERY LED (34)
will stay off, indicating usable battery strength. In the case of a dead or low battery,
the low battery LED will light red continuously, indicating that the batteries should be
replaced with fresh ones.
To preserve battery life, turn the transmitter off when not in use. To turn the transmitter
off, slide the RF POWER (35) switch to the OFF position. The POWER ON LED
(33) is not lit up, indicating the unit is off. The MUTE ICON (6) on the receiver
should be on, muting the audio out.
At power off the transmitter will store the last settings entered and re-display them at
the next power on. The default factory setting is Group 11, Channel 01.
For optimum performance, an AUDIO INPUT LEVEL (30) is provided. Adjust the
gain by turning the control with a small screwdriver. It is recommended that the level
be set at about 1/2 maximum. Experiment and set for maximum possible gain without
audible distortion on the high level peaks. (Note: Turning down the gain too much
can compromise the signal-to-noise and it is not recommended.)
The microphone is now ready to use. The diversity A/B INDICATORS (9) on the
U-800 receiver should now be on, indicating a received signal from the transmitter.
When ready to speak, slide the AUDIO MUTE (36) to the ON position. The MUTE
ICON (6) on receiver should be off. Adjust the volume of the receiver as per the Au-
dio Output Microphone Connection section of the above U-800 receiver instructions.

Note: The windscreen of the UH-800 functions as a built-in antenna. For proper
operation, never remove the windscreen during use, or exchange with another type.
For optimum range maintain line-of-sight between the transmitter and the receiver
whenever possible. Holding the microphone tightly, bridging across the windscreen
and Mic tube, will also lessen range. Hold by the Mic tube housing only for optimum
operation.
Note: Observe care in selecting P.A. volume, transmitter location and speaker
placement so that acoustic feedback (howling or screeching) will be avoided.
