Hi
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.

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.
