One year product warranty
Warranty description
1. Be sure to put the warranty label indicating purchase date on the bottom of
equipment to ensure your interest in maintenance and service.
2. Product warranty, starting on the purchase date indicated on“warranty label”, will
last for one year; if the equipment does not have “warranty label”, the warranty
period is 15 months from the manufacturing date. If a microphone is broken but
not sent back with the equipment, the warranty period is 15 months from the
manufacturing date of the microphone.
3. Within the warranty period, if the equipment is broken under normal use as
instructed in manual, please contact the original selling store for repair.

Lock :push and hold “Lock” for 2 seconds to lock the buttons in order to
prevent pushing any button by accident.
Remoset U : this allows user to synchronize the transmitter after modifying a
parameter. Push “ ” to synchronize the settings to the transmitter.
Remoset indicator : this shows the current pairing status. It ashes rapidly
when data is being transmitted and the ashing stops when the synchroniza-
tion is completed. However, the ashing slows down if synchronization fails
after a period of time of pairing attempt.
Ultrasonic transmission unit: it transmits digital pairing data at ultrasonic fre-
quency. When setting, direct the ultrasonic receiving unit of the microphone to
the ultrasonic transmitting unit of the receivers. The eective range is 30º on
both sides with the optimized distance at 30cm.
