CS-W4C Wireless Conference System

Product Information

The CS-W4C Wireless Receiver is a UHF PLL 4-channel wireless
conference system receiver made by Professional Co., Ltd. It
features JTS 2.4G RF Synchronizing Technology and comes with a
one-year warranty card. The warranty is valid for one year starting
from the date of purchase shown on the warranty label attached to
the product; alternatively, the warranty is valid for 15 months
starting from the date the product was manufactured if the warranty
label is missing on the machine.

Product Usage Instructions

Ensure that the warranty card is attached at the bottom of the
machine to ensure the validity of warranty service.
If malfunction occurs under normal operations according to the
instruction manual while the warranty is still valid, call the shop
where you purchased the product for warranty service.
Return both the machine and microphone back to the shop for
service, since this makes it easier to identify where the possible
problem is and determine whether a service fee is needed.
JTS will provide service free of charge while the warranty is
still valid. However, a fee for parts and/or service may be charged
for certain damages or if the warranty label is not found on the
machine or is damaged to the point that the validity of warranty is
not recognizable.
Keep the warranty card at a safe place, as the warranty is
invalid with a lost warranty card.
Refer to the instruction manual for notes on system operations,
features, specifications, parts, connection, installation, and
operation.

Warranty Service
1. The warranty card must be presented with the date of purchase and attached at the bottom of the machine to ensure the validity of warranty service.
2. The warranty is valid for one year starting from the date of purchase shown on ”warranty label” attached to the product; alternatively, the warranty is valid for 15 months starting from the date the product was manufactured if the ”warranty label” is missing on the machine. If the microphone is returned for service but with the machine, the warranty is valid for 15 months starting from the date of manufacturing shown on the microphone.
3. If malfunction occurs under normal operations according to the instruction manual while the warranty is still valid, please call the shop where you purchased the product for warranty service.
4. It is important to return both the machine and microphone back to the shop for service, since this makes it easier to identify where the possible problem is and determine whether a service fee is needed.
5. JTS will provide service free of charge while the warranty is still valid. However, A fee for parts and/or service may be charged for the following:
a. Damage due to natural disaster or any other irresistible factors;
b. Damage due to dropping, immersion in water, exposure to high humidity, corrosion, ingress of alien objects, or loss of parts;
c. Consumables are not part of the warranty; or
d. The ”warranty label” is not found on the machine or the ”warranty label” is damaged to the point that the validity of warranty is not recognizable.
6. Keep this warranty card at a safe place, as the warranty is invalid with a lost warranty card.

1. Notes for system operations
· Before connecting to power, make sure the voltage marked on equipment is the same as that on the power socket.
· Do not place the machine at a place where high temperature and humidity are expected.
· Do not operate the system with wet hands. · Keep the machine away from any heat or ignition source. · Before setting up the machine, make sure that the volume is set at the minimum
for both the mixer and amplifier. · Caution : The suitable environment for this product is with a temperature
between -10°C (14°F) and +50°C (122°F).
2. Features
· CS-W4C is designed with JTS newest wireless and conferencing technology. It provides maximized compatible channels with a given bandwidth. Built in logic circuit provides conferencing feature. A microphone assigned with priority will work as a chairman unit. It overrides other microphones. Logic setting of one CS-W4C receivers can be cascaded. A microphone with priority in one receiver will also have priority in a cascaded system. JTS patented synchronizes all four microphones simultaneously by push one button.
· The microphone is of 108 MHz bandwidth(MAX). This feature allows more attendants to join the conference.
· Antenna outputs and AC power supply are designed to be cascaded.

2.REMOSET successfulthe blue indicator lights up on the transmitter for 3 seconds and that on the receiver stops flashing.
3.REMOSET failedif the blue indicator flashes slowly on the receiver, check that (1) The ”frequency range labels” on ”both” the receiver and transmitter are the same; (2)”Pairing” in the function menu of the transmitter is ”activated;” (3) The ”Device ID” on the transmitter is the same as that on the receiver; and (4) Transmitter battery is low (synchronization is impossible when battery is low).
*It should be avoided to have two or more receivers on REMOSET when REMOSET is used, as sometimes it prevents pairing due to the mutual interference of REMOSET signals.

8. Notes for the product
(1)For the optimized reception, keep the receiver 3m or more away from the transmitter.
(2)Receivers and transmitters shall be kept at least 50cm away from any metal object.
(3)Do not point the receiver directly into a speaker or there will be annoying feedback noises.
(4)It is recommended to hold the transmitter (microphone) at the middle section for the optimized audio pickup.
(5)In case that the microphone is not used for an extended period of time, it is recommended to remove the batteries from the battery bay in order to prevent electrolyte leaks from damaging the transmitter.
(6)When changing the batteries, it is recommended to change both batteries of the same manufacturer for the optimized power performance.
IMPORTANT NOTE The changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment. To comply with the FCC RF exposure compliance requirements, no change to the antenna
or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void user’s authority to operate the device. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
