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

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 ampli󺸾er.

• The system features the latest anti-interference digital code

circuit design that is proven to isolate the interference

between the system and the outside world.

• Automatic scan

• Provided with antenna booster power

• JTS patent: the latest RF allows the transmission of

not only frequency, but also data such as sensitivity, low cut,

transmission power and key lock to the transmitter.

• With one push of the key, upto four transmitters

can be synchronized.

• RF ''no signal'' alert on LCD display

• AF ''microphone mute'' alert on LCD display

• Transmitter ''low battery'' alert on LCD display

• Antenna and power cascading for improved performance
