SYSTEM OVERVIEW
LIMITED WARRANTY
This wireless system is a portable, high-performance wireless system composed of the
CGS-TM Transmitter and CGS-RM Receivers. The system allows one-way
transmission of voice to group members using an FM radio signal. Using the system
helps group members overcome background noise and distance from the person
speaking.
Our products are engineered, designed, and manufactured under carefully controlled
conditions to provide you with many years of reliable service. CGS warrants the
wireless system against defects in materials and workmanship for FIVE (5) years.
During the first five years from the purchase date, we will promptly repair or replace
the wireless system.
The wireless system can be used for large or small groups and in noisy or quiet
environments.

ABOVE, BOTH EXPRESS AND IMPLIED, WITH RESPECT TO THE CGS-TM, CGSRM, INCLUDING BUT NOT LIMITED TO, ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. CGS SHALL
NOT BE LIABLE TO ANY PERSON OR ENTITY FOR ANY MEDICAL EXPENSES OR
ANY DIRECT, INCIDENTAL OR CONSEQUENTIAL DAMAGES CAUSED BY ANY
USE, DEFECT, FAILURE OR MALFUNCTIONING OF THE PRODUCT, WHETHER A
CLAIM FOR SUCH DAMAGES IS BASED UPON WARRANTY, CONTRACT, TORT
OR OTHERWISE, THE SOLE REMEDY FOR ANY DEFECT, FAILURE OR
MALFUNCTION OF THE PRODUCTS REPLACEMENT OF THE PRODUCT. NO
PERSON HAS ANY AUTHORITY TO BIND CGS TO ANY REPRESENTATION OR
WARRANTY WITH RESPECT TO THE CGS-TM, CGS-RM. UNAUTHORIZED

Your wireless system has two principal parts: the transmitter and the receiver. Much
like a miniature radio station, the transmitter and microphone pick up the sounds you
want to hear and broadcast them over an FM radio signal. The receivers and
headphones are used to pick up the broadcast up to 100 meters away.
To avoid difficulties, please read through these instructions as you begin to use the
system. Then save them for questions that arise as you continue to use your system.

SAFETY INFORMATION
HEARING SAFETY
CAUTION!
This product is designed to amplify sounds to a high volume level
which could potentially cause hearing damage if used improperly.
To protect your hearing and the hearing of others:
1. Make sure the volume is turned down before putting on the
earphone or headphone. Then adjust the volume to a comfortable
level.
2. Set the volume level at the minimum setting that you need to hear.
Operation is subject to the following two conditions: (1) this device may not cause
interference, and (2) this device must accept any interference, including interference
that may cause undesired operation of the device.
3. If you experience feedback (a squealing or howling sound), reduce
the volume setting and move the microphone away from the
earphone or headphone.
If TV channel 13 is used in the area, the installer shall reduce or adjust the RF radiated
power so that nearby TV channel 13 receivers do not receive radio interference from
the system.
4. Do not allow children or other unauthorized persons access to
this product.
BATTERY SAFETY AND DISPOSAL
CAUTION!
Do not attempt to recharge disposable batteries, which may
explode, release dangerous chemicals, cause burns or other
serious harm to the user or product.

IN CASE OF DIFFICULTY
OPERATING INSTRUCTIONS
If your wireless system is not working, check the following:
USING THE CGS-TM TRANSMITTER
1. Plug the microphone cord into the “Mic” jack on top of the transmitter.
2. Turn the power switch on top of the transmitter to “On.”
3. Position the Headset Microphone boom as close to the wearer's mouth as possible
without actually touching. Lapel Clip microphones should be attached to a collar or
lapel, as close to the wearer's mouth as possible.

Note On The Transmitter Antenna:
The microphone cord is the transmitting antenna. Do not bunch up the cord, wrap it
tightly around your body, or wrap it around the transmitter. For maximum range, the
cord should hang as straight as possible. The transmitter can be placed in a pants
pocket, or clipped onto a belt or waistband. Make sure the transmitter is turned OFF
when not in use.
1. Read through the manual and user guide carefully to verify proper setup and
installation of your system.
2. Make sure the batteries are fresh or completely charged and that the “plus” and
“minus” terminals are installed correctly.
3. If the rechargeable batteries will only work for a short period of time (less than 1
hour) even after they are fully charged, they must be regenerated. Leave them in
the receiver or transmitter with the unit turned on, for 5–6 hours. Then turn receiver
or transmitter off, place it in the charger, and charge for 14–16 hours. This should
restore normal battery life. Rechargeable batteries will gradually lose their capacity
over time and should be replaced every year.
4. Make sure the microphone is plugged into the CGS-TM Transmitter and the
headphone is plugged into the CGS-RM Receiver.
5. Move the transmitter and receiver closer together. You may be out of range. When
using the system indoors, it’s normal for the signal to momentarily disappear in
certain locations. This is called a “drop-out.” Moving a few feet will restore the
signal.
6. Do not try to use more than one transmitter on the same channel in close proximity
to each other. MORE THAN ONE TRANSMITTER ON THE SAME CHANNEL
WILL RESULT IN INTERFERENCE IF THEY ARE CLOSE TOGETHER. Keep the
transmitters at least 100 meters apart or use separate channels for each system
used.
7. If you are still hearing interference on the receivers, turn the transmitter off and
listen with a receiver. If you hear the interference with the transmitter off, you need
to change to a clear channel.
NOTICE
We assumes no liability for improper use or operation of this equipment. The user is
cautioned to operate the volume controls at the lowest acceptable level, and in a
manner that will not cause damage to hearing. Ear pieces and accessories should be
worn using good judgment and for their intended purpose.
Users are cautioned that changes or modifications not expressly approved by CGS.
could void the user’s authority to operate the equipment.

USING THE CGS-RM RECEIVER
BATTERY INFORMATION
1. Plug the earphone or headphone into the headphone jack on top of the Receiver.
INSTALLATION
Press the batteries into place, observing proper battery polarity. Incorrect insertion of
the battery is difficult, and if forced, may cause both mechanical and electrical damage
to transmitters or receivers not covered by the warranty. Units will not work with the
battery incorrectly installed.
2. Place the headphones over your ears.
3. Turn the power on by rotating the volume control thumbwheel on top of the
Receiver.
4. Adjust the receiver volume control to a comfortable listening level. You should be
able to hear someone speaking into the transmitter microphone.

NON-RECHARGEABLE BATTERIES
In normal use, two AA 1.5 V alkaline batteries will last about 30 hours in the CGS-TM
Transmitter and approximately 60 hours in the CGS-RM Receiver. If the sound
becomes weak or distorted, replace the batteries. Do not leave dead batteries in the
receivers. Battery corrosion is not covered by the five year warranty.
RECHARGEABLE BATTERIES
Note On The Receiver Antenna:
The headphone cord is the receiving antenna. Do not bunch up the cord, wrap it tightly
around your body, or wrap it around the receiver. For maximum range, the cord should
hang as straight as possible. The receiver can be placed in a pants pocket, or clipped
onto a belt or waistband. Make sure the receiver is turned OFF when not in use.
The CGS-TM Transmitter and CGS-RM Receivers can use rechargeable AA batteries.
On an overnight charge, these NiMH batteries are designed to operate a CGS-TM
Transmitter for approximately 24 hours, and CGS-RM Receivers for 50 hours.
The battery installed in the transmitter / receiver may be recharged only if it is a NiMH
battery.
Important Rechargeable Battery Information
They must be charged for a complete charge cycle before the first use (approximately
15 hours). Rechargeable batteries will need to be replaced after 1–2 years of use. Do
not dispose of batteries in fire. Do not open batteries — toxic chemicals inside.
!! IMPORTANT WARNINGS !!
DO NOT ATTEMPT TO RECHARGE ZINC CARBON (“HEAVY DUTY”),
ALKALINE, OR LITHIUM BATTERIES!
DO NOT ATTEMPT TO RECHARGE DISPOSABLE BATTERIES! These batteries
may heat up and explode, causing possible injury and damage to the equipment.
Avoid shorting the plus and minus battery terminals together with metal objects.
Battery damage and burns can result!

CHANNEL SELECTION AND SETTING
HINTS FOR USING THE SYSTEM
1. Press “SET” button (at least 3 sec.) to release the lock.
Normal operating distance between the transmitter and receiver is about 100 meters.
The operating range will vary in different buildings and surroundings. In some
locations, the signal may momentarily disappear. This is called a “drop-out” and is due
to reflection and cancellation of the radio signal. Moving a few feet will restore the
signal.
2. Press +/ – to select channel.
3. Press the “SET” button (at least 3 sec.) again to lock the channel.
Keep the transmitter and receiver units at least a meter apart. If the transmitter gets
too close to a receiver, it can overload the receiver, causing noisy reception or
blocking of the signal.
Do not use more than one transmitter on the same channel (frequency) at the same
time unless they are physically separated by more than 100 meters. Operating more
than one transmitter on the same channel at the same time in the same place will
result in interference.
