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.

2. Features
• Before connecting to the main power supply, check that the power
requirements shown on the nameplate of the machine meet the output of the
adaptor.
• 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.
• 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.
