Pairing
Once the parameters are set, push the “ ” button and the digital
pairing data will be sent to the transmitter via ultrasonic transmitter for
parameter synchronization. The indicator will ash rapidly while the data are
being transmitted. When the synchronization is completed, the receiver will
receive the corresponding data and the indicator will stop ashing. If the signal
is not received for a certain period of time, the indicator will ash slowly to
inform pairing failure (the slowly ashing indicator can be reset by pushing any
button).
Note: The best pairing distance is 30cm, ±30º.
Others
The transmitter’s battery level is also shown on the LCD display. If the battery level is
≤ 2V, the frame around the battery level will ash and the backlight turns into red as a
warning.
