Remoset: this shows the current pairing status. It ashes rapidly when data
is being transmitted and the ashing stops when the synchronization 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
frequency. When setting, direct the ultrasonic receiving element of the micro­phone to the ultrasonic transmitting element of the receivers. The eective
range is 30º on both sides with the optimized distance at 30cm.
