1. Installation method of sensor
a) sensor is installed at bottom of bait boat hull
b) sensor is installed at side of bait boat hull
2. Sonar Working Instruction
Note: when sonar works, the signals were remitted in the direction as instructed.
So, in the area A and area B, there should be no any obstacle, otherwise the sonar
signals will be ¡°blocked¡±, thus sonar unit will not be able to receive the signal
normally, which will cause short Remote Control distance, or abnormal display on the screen.
