8-1. Precaution before adjustment
Before adjustment, read the following data and record them.
When the SY-169 board is replaced, read out the data before the
replacement, and record them.

attached to.
Be sure to check because if attached incorrectly, the screen will vi-

Precautions on the Parts Replacement
The PITCH sensor and the YAW sensor are different parts.
Precautions on Angular Velocity Sensor
The sensor incorporates a precision oscillator. Handle it with care as
if it dropped, the balance of oscillator will be disrupted and opera-
tions will not be performed properly.
