INSTALLATION OF CABLE 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.7 )
When the audio cable goes through the cable restraint, it will prevent sweat from going
directly into the unit via the connector. This is another advantage of the cable restraint.
Aerobics
Fig.7
Depending on customer requirements, Lavalier / Headset microphone or
instrument inputs can be connected to the transmitter via the audio input
connector. User is free to choose the various input sources but is advised to take
note that connector used must be compatible to each other. The pin
configurationsfor the mini XLR connectoris in Fig.8.

IMPORTANT SAFETY INSTRUCTIONS
READ BEFORE OPERATING
MW163U
MW163U

Now switch on the transmitter (please refer to transmitter operating instructions).
The RF indicator will light up when the correct channel is selected, indicating that
the radio signal transmitted has been received.
Use RF test button to test if there is interference around. If there is interference
around, the RF signal level LED will light up. The receiver is indicating to switch to
another frequency.
When an audio signal into the microphone, the audio indicator will flash to show
the strength of the audio level.
OPERATING INSTRUCTIONS
Before switching on the receiver, make sure that the units antenna system is
attached and placed at 45 degree angles opposite of each other (Polarization
Diversity) and that the unit is positioned in an unobstructed location.

The MW165U has a module design. To change or replace a capsule, Open the grill to pull out
and plug in the capsule as shown in the following figure.

Before operation, please check and make sure that transmitter & receiver are of
matching channels.
To switch on the microphone, put the switch to "ON" position. The red LED indicator will
light briefly indicating that battery is fresh. When the RED LED light is steady, it indicates
that battery is weak, thus a replacement is necessary.
For best results, an alkaline battery is recommended. Please remove the battery if the
transmitter is not to be used for a longer period.
When necessary, the MW165U microphone capsule can be replaced by pulling out and
plugging in the new one.
For close singing or speaking, put the sensitivity switch to N (Normal) and for mic stand
applications or when the speaker stands away , put the sensitivity switch to
H (High). Be careful to put back the sensitivity switch to N for close singing as H (High)
sensitivity for close vocal applications may cause distortion.
When holding the handheld microphone, please do not hold the antenna end of the unit
for it will severely affect the efficiency of the transmission range.

RECEIVER INSTALLATION
Audio output connection
There are two audio outputs on the back of the Diversity RDU216
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.
For best operation, the receiver should be at
least 1m above the ground and at least 1 m
away from a wall or metal surface to minimize
reflections. The transmitter should also be at
least 1 m away from a wall or metal surface to
minimize reflections. The transmitter should
also be at least 1 m away from the receiver, as
shown in Fig. 5
Keep receiver antennas away from noise
sources.
True Diversity:
True Diversity utilizes two receiver channels to
avoid “dropout” or loss of RF signals created
by waves propagating in a reflective, or
multipath environment. The RDU216
incorporates an advanced microprocessor that
selects the audio from the antenna and
receiver channel with the best RF signal.

CAUTION
The positive ( + ) pole of battery must face downward. 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

RF INTERFERENCE
used.
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 below.
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.
Receiver Squelch Control
The squelch control on the back 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 to the lowest position which reliably mutes the unwanted
RF signal.
RF Test Function
The most unique feature of this unit is the RF test manual scanner
feature. By pressing the RF test button, the user is free to scan
through all the channels to look for a clean channel before
operation. When the RF test button is pressed, a lighted RF
indicator means that the selected channel is occupied and
interference will occur when

If an external antenna is used a low loss 50-ohm RF shielded cable must be
used and the length of the cable should not exceed 3 meters.
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,
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.
Before system operation, please make sure that the corresponding receiver
MUST have the same channel number as the transmitter.
Before making any channel change, please switch off the power supply. The
synthesized program works in such a way that a change of channel will only
take place after a power off and on action. Otherwise, the previously selected
frequency will stay unchanged.
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.
Turn the transmitter off when it is not in use. Remove the batteries if the
transmitter is not to be used for a period of time.
