OPERATING INSTRUCTIONS  
TIPS  
U-1000, U-2000 Receiver  
• For operation with external antenna, low loss RF shielded cable should be  
used and the length of the cable should not exceed 3m.  
• Do not place the receive antenna within 1 meter of another receiver or  
antenna.  
next location. After finishing the edit hold the SET (7) button until the curser  
stops blinking.  
4. Group and Channel (Preset)  
• The receiver antenna should be kept away from any metal surface.  
• If the Volume Control of the receiver is set too high, it may over-drive the input  
of the mixer, causing distortion. Conversely, if the receiver output is set too  
low, the overall signal to noise ratio of the system may be reduced. Adjust the  
output level of the receiver such that highest sound pressure level going into  
the microphone causes no input overload in the mixer, and yet permits the  
mixer level controls to operate in their normal range (not too high or too low).  
This provides the optimum signal to noise for the entire system.  
• Before inserting the batteries, please make sure that they are inserted  
according to the correct polarity.  
• For PLL frequencies agile version, before operation please make sure that the  
corresponding receiver MUST have the same frequency group and channel  
number as the transmitter.  
• After making a channel change, please make sure that the corresponding  
change is made on the matching receiver also. To be exact, changes MUST be  
made at both the transmitter and receiver.  
• Use only brand new Alkaline batteries. Do not use “general purpose “  
batteries. When batteries are weak, replace the batteries altogether at the  
same time. Do not mix and use new and old batteries together.  
• Position the receiver such that it has the least possible obstructions between it  
and the transmitter. Line of sight is best!  
• The transmitter and the receiver should be as close as possible but not less  
than 1 meter.  
• A receiver cannot receive signals from two or more transmitters  
simultaneously.  
Choose the UHF-1000 operating frequency by  
selecting one of the 24 Groups and one of the 40  
Channels in each group. The first two top digits on  
the left are the Group and the second top two  
digits to the right are the Channel.

6. Channel Frequency  
Choose an operating frequency by selecting the  
Channel and Group. Same as above Group and  
Channel menu, except it displays the Carrier  
frequency.  
• Turn the transmitter off when it is not in use. Remove the batteries if it is not to  
be used for a period of time.

(Note: Scratchy noises can sometimes occur when some electric guitars with  
dirty pots or connections are used with any wireless system. Therefore, the  
supplied INSTRUMENT CORD has a factory installed capacitor inside the 1/4”  
plug. This 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 give you scratchy noises, we suggest these steps to eliminate  
them:  
7. Squelch Level  
There are eight choices between -100 and -65  
dBm. In the Squelch Level Menu, hold the SET (7)  
button for 3 seconds. The curser will blink in the  
Squelch Level selection, use the UP (4) or DOWN  
(5) buttons to cycle the selections. After finishing the edit hold the SET (7)  
button until the curser stops blinking.  
SQUELCH LEVEL  
-100 dBm (1)  
1) Make sure all guitar volume and tone pots are clean and all contacts are  
solid-this is very important.  
2) A 47pf capacitor soldered across the hot to ground terminals of the guitar’s  
volume and tone pots will provide extra filtering.)  
The RF and AF level meters, diversity operation, and audio output connections  
of the receiver are described in the System Operation section (pgs 16,17).

SYSTEM OPERATION  
OPERATING INSTRUCTIONS  
UH-1000 Handheld Microphone  
(Note: The UH transmitter CAP (7) must be removed before installing the USB  
cable.) (Note: Only one transmitter can be used with one UHF-1000 receiver. It  
is not possible to use two transmitters on the same frequency and mix the  
output of these transmitters into one wireless receiver. If you have any  
questions, please contact the Nady Systems Customer Service Department.  
See SERVICE section, pg. 21.)  
TRANSMITTERS SETUP  
Installing Batteries  
UH-1000 transmitters require 2 “AA “ size batteries to operate. Insert the  
batteries according to the correct polarity as indicated. To open the battery  
compartment, press the release latch and open the cover.  
CAUTIONS AND TROUBLESHOOTING  
Feedback  
(CAUTION: Many batteries are known to have leakage problem of conductive  
and corrosive liquid. Please observe the rule to remove the batteries if they are  
not to be used for a period of a few days. This battery compartment is designed  
to accommodate the most common size Alkaline batteries.)  
Observe care in selecting P.A. volume, transmitter location and speaker  
placement so that acoustic feedback, howling and screeching, will be avoided.  
Please also note the pickup pattern characteristics of the microphone selected.  
Omni directional mics pick up sound equally from all directions, and are prone  
to feedback if not used carefully. Unidirectional mics are more resistant to  
feedback, but pick up sound sources best that are directly in front of the mic.  
Also, mics that are farther from the sound source, such as lavaliers, require  
more acoustic gain and thus are also more prone to feedback than close-source  
mics such as handheld or headworn models that are used close to the mouth.  
Powering the Transmitter  
To turn ON, Press the POWER SWITCH (5), for 1 second.  
The LCD DISPLAY (2) will flash the company and model number. Then the  
menu will appear.  
To turn OFF, Press the POWER SWITCH (5) for 3 seconds and release. The  
transmitter will turn off.  
Microphone Damage  
Headset and lavalier mic users, note that the microphone element can easily be  
destroyed by the buildup of salts and minerals from perspiration and saliva. It is  
good practice to put a windscreen on the mic at all times to protect it.  
Auto Turn Off function. If the transmitter Audio mute switch is in the OFF  
position and the transmitter is left On. It will turn OFF after 30 minutes. This  
foolproof feature will save the batteries.  
No Audio  
Menu pages in Preset or User mode  
Cycle Menu pages by pressing the UP (9) or DOWN (10) buttons.  
If you’re not getting audio through the system, carefully check all setup. The  
receiver and transmitter must be set to operate on the same RF channel.  
Transmitter Setup Menus  
Control Menus have two modes, Preset and User.  
To make changes Hold the SET (8) button for 2 seconds and use the UP (9) or  
DOWN (10) buttons. To save changes hold the SET (8) button for 3 seconds.  
RF Interference  
If you encounter receiving interference (from other than an operating TV  
station), often it can be overcome by adjusting the receiver’s squelch control.  
Please note that wireless frequencies are shared with other radio services.  
According to FCC regulations, wireless microphone operations are unprotected  
from interference from other licensed operations in the band. If any interference  
is received by any Government or non-Government operation, the wireless  
microphone must cease operation or change frequencies. The above statement  
is valid only for use in the U.S.A.  
The transmitter will remember the last Menu of User Name, Group and  
Channel, or User Edit, when it is turned off. That menu will appear when it is  
turned on.  
1. User/Preset mode  
In the Preset or User menu, hold the SET (8) button for 3 seconds. The curser

UH-1000 Handheld Microphone  
Connecting Audio Output  
There are two audio outputs on the back of the receiver. Mic-level balanced and  
Line-level unbalanced. Use shielded audio cable for the connection between the  
receiver and the mixer. If the mixer / amp is a 1/4” phone jack, connect a cable  
1
from the 1/4” unbalanced audio output from the receiver.  
The 1/4” output can be set to either mic line level using  
the MIC LINE SWITCH (12) If the mixer has an XLR  
input, connect a cable from the balanced XLR audio  
output from the receiver to the mixer input. XLR output  
connection is shown above.

(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.)  
Receiver Volume  
The UP or DOWN buttons on the front panels serve as the Volume Controls of  
the receiver. It can be pressed at any moment. The normal VOLUME setting is  
13 for one-to-one unity gain. If the volume is set too high, you may overload  
your mixer or amp.

Receiver Squelch  
There are eight choices between -100 and -65 dBm. Use the lowest setting  
possible. If there is audio output from the receiver when your transmitter is OFF,  
adjust the squelch control so the system will receive the signal from your  
transmitter but squelch or eliminate the unwanted background RF noise. This  
adjustment can cause a reduction in usable range of the wireless transmitter, so  
set the control to the lowest position that reliably mutes the unwanted RF signal.

Receiver Diversity Operation  
During operation only one of the A or B Diversity display icons will be lit,  
indicating the receiver’s True Diversity circuitry is selecting antenna input A or B  
for the best signal. This is normal and ensures that the received audio will not  
be interrupted. Sometimes, especially at ranges greater than 75 feet, the  
squelch circuit will activate in certain locations of the transmitter with respect to  
the receiver. Such areas are called “null spots” and indicate that the transmitter  
is out of range for that given location, and the user should move closer to the  
receiver or to another area to re-establish the radio link.

rear panel of the receiver. Plug the other end of the cord into an amplifier,  
effects, or mixing board. Adjust the VOLUME on the UHF-1000/2000 receiver  
until the volume level is 13 or comfortable, depending on your application . This  
setting is roughly equivalent to a direct instrument cord connection. Turning the  
volume up to MAX will provide 4 dB gain over a cord.  
Connecting instruments and microphones to the UB transmitter depends on  
customer requirements. Lavalier / Headset microphone or instrument inputs can  
be connected to the bodypack transmitter via the audio input connector.

For microphone use, either the BALANCED output XLR or the 1/4” line level AF  
OUT jack can be utilized. Set the MIC LINE SWITCH (12) to either mic level or  
line level output depending on your application . Plug a cord with either  
connector into the appropriate output and plug the other end into your amplifier  
or mixing board. (Note: Make sure the volume is turned down when making  
connections.)  
The LCD display battery icon shows the battery condition. When the battery is  
weak, the Battery Weak /Audio Mute LED (3) will stay on.  
The microphone and instrument connections, Mute, and level adjustments of the  
transmitter are described in the System Operation section (pgs. 15, 16).  
Microphone Use: (with either a lavalier or headworn microphone)  
Connect the mini XLR connector from the LAVALIER or HEADWORN MIC to  
the transmitter input connector. To use the lavalier mic, attach it at chest level.  
Do not place it too close to the mouth; a distance of about six inches usually  
works best. To use the headworn mic, place it on the head and adjust the boom  
so that the mic is about one inch to the side of the front of the mouth.
