CW200 Introduction
The CW200 radio microphone system has the following features:
Dual receiver covering UHF frequencies 602 – 634 MHz subject to local enforcement laws for
licence free transmission.
EIA-standard metal 1U - rack mount receiver.
Bright and easy-to-read multi function LCD display shows RF/AF, diversity strengths;
transmitter battery level. The display will also show setup of selected channel, frequency,
mute and other working status.
Auto-scan and lock on to an open interference free frequency.
Infrared upload of function changes from the receiver frequency to the transmitter.
PLL (Phase Lock Loop frequency control) design ensures transmission reliability, "Noise
Lock" squelch effectively blocks stray RF noises
Each receiver has 32 selectable channels. Total 64 channels,
The table top boundary layer transmitter microphone has a cardioid polar pattern ensuring
good sound reproduction between 120 Degrees angle of acceptance. Superior offset noise
rejection outside of the angle of acceptance.
Transmitter continuous battery life using good quality alkaline batteries approx 10 hours.
Heavy die-cast case and non-slip silicon foam bottom pads minimize coupling of surface and
vibration pickup.
Notes on Installation:
For better operation the receiver should be at least 3ft. (1m) above the ground and at least
3ft. away from a wall or metal surface to minimize reflections.
UHF antennas connected to the receiver should be positioned in the shape of a “V” (both
45°from vertical) for best reception.
Keep antennas away from electrical noise sources such as computer, digital equipment,
motors, automobiles and neon lights, as well as away from large metal objects.
Keep open space between the receiver and transmitter for better reception. Any large metal
objects will cause a reduction or loss of signal.

Powering up
1. Make sure your external equipment is connected and powered up
2. Press the power button on the CW200 Receiver. The two receiver displays will light up and
show the receiving frequencies.
3. Briefly press the power button on the transmitters. The display will light up and the frequency
will show in the display it should be the same as one of the receivers frequency display.
4. The transmitters and receivers are factory set to CH 04 and CH 46. The transmitters are
factory set to latching. Speak into the transmitter and audio should be heard. Briefly press the
power button on the transmitter to mute the audio, press the power button again to restore the
audio. Press and hold the power button for 3 – 4 seconds to turn of the transmitter.
Changing the transmitter frequency
The transmitter frequencies can only be adjusted by the receiver. The frequency is set on the
receiver then sent by Infrared Frequency to the transmitter.
Note: When transferring a new frequency to the transmitter make sure that the transmitter is switched
on and is placed in front of the left side of receiver as shown below.

To change the transmitter frequency.
Important: Each receiver (A and B) has its own independent setup buttons for changing
frequency and other parameters on each of the transmitters. Make sure you use the correct setup
buttons for setting up each respective transmitter. As the transmitters do not carry any
identification and look identical, It may be useful to mark or apply an ID to each of the transmitters
A and B to ensure that the correct transmitter / receiver is being operated, this will be especially
be useful if several systems are in operation.
.
a, Press the required CH A or CH B ﹤/ ﹥ button once on the receiver front panel to select a new
frequency. The display will flash and after short time will remain stable.
b. Position the transmitter (powered up) as shown above and press the Synch button on the front
panel and SYNCH >>> will show indicating that the new frequency is being transmitted to the
transmitter. After a few seconds the display will return to normal and the receiver and transmitter
old frequency will have been changed to the new frequency. If >>>> continuous more then 20
seconds then make sure the transmitter is powered up and its IR sensor is facing the receiver
sensor as shown above.
In cases where there are other transmitters being used and causing interference Press and hold
﹤/﹥button on the receiver for 3 seconds and the receiver will auto-scan and lock on to an open,
interference-free frequency. Now press the SYNCH button to transfer this new frequency to the
transmitter.
Menu options
1. To enter the menu mode: Press and hold the Set button (CH A or CH B) on the receiver for 3
seconds until DISPLY shows, press ﹤/ ﹥each time the < / > button is pressed the options
shown will change, LOCK or SQUELCH, DISPLAY modes.
11
Page 13
2. DISPLAY option. This will allow the display to show either frequency or the Channel number.
Enter the menu mode as described in point 1 above. With DISPLY showing press the <
button to select Frequency or > button to select the Channel number, Frequency or Channel
will show flashing in the display. Press the SET button to confirm your choice. The display will
then apply the changes and return to its normal operation. To transfer the new change to the
transmitter, place the transmitter (powered up) in front of the receiver as shown in fig 1 under
Changing the transmitter frequency then press the SYNCH button. >>> will show whilst the
new data / changes are being sent to the transmitter.
3. SQUELCH. To prevent unwanted noises occurring the receiver has 0 – 50dB squelch settings
in 5dB steps (default is 0dB). To change the squelch level enter MENU mode as detailed in
point 1 above and press > or < button until SQUELCH shows. Press SET button and a
flashing dB level will show, press the < or > button until the desired new squelch setting
shows. Press the SET button to confirm the changes.
4. LOCK. To prevent accidental powering off the receiver or changes of settings on the receiver.
Select LOCK in the menu. Enter MENU mode as detailed in point 1 above and press > or <
button until LOCK shows. Press SET button then press < or > buttons to change LOCK status
to On or OFF. Press SET button to confirm the new changes. The display will return to normal
operation. To power of the receiver LOCK must be OFF so it will be necessary to enter the
MENU mode as described in point 1 above then follow above instructions to place LOCK OFF
mode.

Replace transmitter batteries
Is the receiver connections to external equipment correct
Is the external equipment powered up
Out of range / bring transmitter closer to the receiver
Noisy audio / poor reception /
Distorted audio
Replace transmitter batteries
Check that transmitter / receiver Frequencies are the same.
Co channel interference / external interference try
changing transmitter frequency.
Receiver antennas close to electrical interference.
Move away from electrical items such as laptops,
