8 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.
9 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.
10 Position the receiver such that it has the least possible obstructions between it
and the transmitter. Line of sight is best!
11 The transmitter and the receiver should be as close as possible but not less
than 1m.
12 A receiver cannot receive signals from two or more transmitters
simultaneously.
13 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.

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, as described
on below.
Please note thatwireless frequencies are shared with otherradio services.
According to FCCrequlations, wireless microphone operations are unprotected
from interference fromother licensed operations in the band.If any interference is
received by anyGovernment or non-Government operation, the wireless
microphone must ceaseoperation. The abovestatement is valid inthe U.S.A.
Receiver Squelch setting
The squelch control setting is per LCD display on the front panel of the receiver is
preset at the factory, but can be adjusted if you must use the system in a high RF
interference area. 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 tothe lowest position which reliably mutesthe unwanted RF signal.
1 If external antenna is used, low loss RF shielded cable should be used and the
length of thecable should not exceed 3m.
2 Do not place the receive antenna within 1 m of another receiver or antenna.
3 The receiver antenna should be kept away from any metal surface.
TIPS TO OBTAIN THE BEST RESULTS
FOR A WIRELESS MICROPHONE SYSTEM
REMARKS
4 If the Volume Control of the receiver is set too high, it may over-drive the input of
the mixer,causing distortion. Conversely, if thereceiver output isset 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 optimumsignal to noise for the entire system.
5 Before inserting thebatteries, please make sure that they are insertedaccording
to the correct polarity.
6 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.
7 Before making any channel change, please switch off the power supply. The
synthesized program works in such away that a change of channelwill only take
place after a power off and on action. Otherwise, the previously selected
frequency will stay unchanged.

RECEIVER INSTALLATION
Audio output connection
There are two audio outputs on the back of the Diversity 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 from the 1/4" unbalanced audio output from the receiver to the mixer / amp.
If the mixer has an XLR input, connect a cable from the balanced XLR audio output
from the receiver to the mixer input. Audiooutput connection asshown below.
For best operation, the receiver should be placed at
least 1m above the ground and 1m away from a wall
or metal surfaces to minimize reflections. The
transmitter should also be at least 1m away from a
wall or metal surface to minimize reflections. The
transmitter should also be at least 1m away from the
receiver as shown.
Keep antennas away from noise source such as
motors, automobiles, neon light, synthesizer,
computer as wellas large metal objects.

First turn onthe Power of the QR-4000U ReceiverBase Unit. Then turn on the
individual power of the SDR-916M receiver module. Select the desired channel by
pressing the channeltact switch and the corresponding channelon the Transmitter.
When Transmitter is turn on, either A or B will turn on meaning signal is being
received. Turn the volume control in clockwise direction will increase the audio
output.
What is the RF Test function key and how to use it ?
It is the manual scan function key. To test this function key, the transmitter must be
shut off. For model with the RF test key, pressing down the key is to disable the
Pilotone lock function.When A or B signal lightsup when this test key ispress ( the
corresponding transmitter mustbe swiched off.), it means that this particular
channel is in used. Select another channel and do the test again until a clean
channel is selected.
What is the SQ ( Squelch ) for ?
When a channelis in used and unpleasant interferencesignal is heard, turn the SQ
in clockwise direction will make the receiver less sensitive and thus less susceptible
to interference. If this still does not solve the problem,please switch over to the next
channel.

INSTALLATION OFCABLE RESTRAINT
To prevent contact noise caused by constant tension applied to the connector,,
a cable restraint is designed such that tension is totally reduced when it is
properly used ( see Fig.6 ).
When the audio cable go through the cable restraint, it could prevent sweat from
going diectly into the electronic board via the connector. This is another
advantage of the cable restraint. Fig.6
UH-1000/VH-1000/UB-1000/VB-1000 these microphone have a sensitivity setting per the SET, UP, DOWN buttons as
described earlier.SQ-916/SQ-316 have a sensitivity switch for close mouth singing and normal speech, please select
level N.( Normal ). For tripod-mount application, please select the level H (high) .
Sensitivity Level Setting
Depending on customer requirements, Lavalier / Headset microphone or instrument inputs could be
connected to thebeltpack transmitter via the audio input connector.User is free to choose thevarious
