7.3 EXPLANATION
7.3.1 MECHANISM DESCRIPTIONS

Outline of the FLAP motion
1. The motion is actuated made by two motors, the forward/backward driving motor (CXB9515) and the angle
driving motor (CXB9516).
2. Analog electric potential generated by the angle encoder is detected to detect angle motion status and motion
position.
3. Memory function for the angle last position is accomplished by the micro processor using the 256 resolution
steps of the VDD.
4. A pulse is detected by the photo interrupter to detect the horizontal motion status.
5. In the case of reset start, the monitor will be in a stored position first, and ejection motion will take place, which
puts the system in the booted up state.
6. Angle adjustment is made by the angle key (+/-).
7. OPEN/CLOSE key makes the monitor stored or ejected, and temporary folding key folds the monitor
temporarily.
8. Setting of the monitor auto storage/ejection ON/OFF and set back ON/OFF at the time of ACC ON/OFF is made
on the navigation menu screen.
9. A backlight is switched-off during forward/backward and storage.

Explanation on the FLAP ejection motion
1. When the OPEN key is pressed or ACC is set to ON while the auto OPEN/CLOSE is being set to ON, angle
driving motor rotates in the 0
°
direction for 500ms. (Pressed down.)
2. After 500ms, the angle driving motor is stopped, and the forward/backward driving motor rotates in the
ejection direction.
3. For a period of 600ms from the time when LIFTSW is switched from H to L, the forward/backward driving
motor keeps rotating in the ejection direction.
4. After 600ms, the forward/backward driving motor is stopped, and the angle driving motor rotates in the UP
direction.
