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.

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).

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.

1. Connect the audio signal cable
   Connect the CS-W4C audio output to a mixer or an amplifier: Audio cable: one end of the XLR or Ø6.3mm audio cable is connected to the ”AF output balanced” of CS-W4C and the other to the audio input of the mixer or amplifier.

2. Connect the power
   Connect AC power cable: insert one end to the receiver’s AC jack and the other to AC power outlet (100~240VAC).
   

Cascading of AC power cable and antennas *Up to 10 units can be cascaded for power/antenna.

*Logic Controller & Voltage Output
When the microphone channel is turned on, the control signal corresponding to this channel will continue to output “High” (+5Vdc). When turned off, the control signal output of this channel will be “Low” (0V). The logic control signals can be used to trigger other applications, such as: the video camera.

Pairing for REMOSET

1. REMOSET：push REMOSET and the blue indicator will start flashing, indicating that the frequency data is being transmitted.
2. REMOSET successful：the blue indicator lights up on the transmitter for 3 seconds and that on the receiver stops flashing.
3. REMOSET failed：if 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.
4. Pairing 4 microphones simultaneously: push REMOSET and the blue indicator starts to flashing. On the display all 4 receiver channels show ”Synchronizing,” indicating that data are being transmitted to all 4 microphones.
5. Pairing a single microphone: push SEL of the receiver channel to be paired.
   Push REMOSET and the blue indicator starts to flash. On the display the receiver channel is ”Synchronizing,” indicating that data is being transmitted to that microphone.

Others
Push ”SEL” below each of the channel volume keys:
Push SETUP to enter the page containing the selections of that channel for parameter settings.
Push REMOSET to start pairing that channel; other channels remains standing by.

When battery is < 1.8V, the transmitter will turn off automatically.
If the microphone is turned off with the mute switch on mute, just slide the switch up to turn the microphone on.

Alert Function

The alert screen will blink slowly under these circumstance:

1. When microphone is under mute mode.
2. When microphone’s power is OFF. 3.When microphone’s battery level is too low.

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.
