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.

8. Notes for the product

1. Notes for system operations

• 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.

2. Features

• 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.

• Up to 36MHz of bandwidth with a maximum of 1440 channels to choose from

• Adjustable squelch level

• Default with 6 groups, up to 22 available

• User-de󺸾ned groups provided

• 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

Pairing for REMOSET

1.REMOSET：push REMOSET and the blue indicator will start 󺸿ashing, 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 󺸿ashing.

3.REMOSET failed：if the blue indicator 󺸿ashes 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 󺸿ashing. 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 󺸿ash. On the display the receiver channel is ''Synchronizing,'' indicating that data is being transmitted to that microphone.

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 perfor mance.

FCC Statement

FCC INFORMATION

The equipment has been tested and found to comply with the limits for a Class B Digital Device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction, may cause harmful interference to radio communication. However, there is no grantee that interference will not occur in a particular installation. If this equipment dose cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on , the user is encouraged to try to correct the interference by one or more of the following measures:

--Reorient or relocate the receiving antenna.

--Increase the separation between the equipment and receiver.

--Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

--Consult the dealer or an experienced radio/TV technician for help.

Notice: The changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

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.

IMPORTANT NOTE: 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.
