11-1 VOLUME ADJUSTMENT
Check the volume value of the steering wheel once a month and adjust it if necessary. At the same time, check the
handling of the steering wheel.
The steering wheel has two volumes. The upper side is for the drive board, and the lower side is for the game board.
Check the volume value of the drive board volume on the DRIVE BD TEST screen, and check the volume value of
the game board volume on the INPUT TEST screen. The drive board volume can also be checked on the 7-segment
display of the drive board. (See 19-2, Step 8.)
The recommended volume value when the steering wheel is straight is “80H +/- 4”.
