•Massage position detector P.C.B is composed of 2 bits. The microcomputer of the main circuit board
w/component is always being sent the ON/OFF (0V/5V) signal of the drive pipe rotation. With the
massage positiondetector P.C.B being 2 bits, the massage position detector P.C.B. is used to detect the
timing of the increase/decrease of the intensity. The intensity adjustment block turns on when
ON/(5V).
•Intensity adjustment P.C.B is composed of 3 bits. It detects only intensity quantity, and detects
protruding quantity(about 0 to 45 mm).
*When dust and dirt get into the detector section of the detector print board, the detection of various
operations becomes impossible, and the signals being sent to the main circuit board change. This leads
to, for example, a malfunctionin the intensity overrun, etc., which results in the blinking of operation
lamps, and then stoppage.
