3.7 G Sensor Calibration

3.7.1 Overview

The G Sensor is mounted on the MA Board to detect the inclination of the
projector. To compensate the variation of the accuracy of the G Sensor
detection among the products, perform this calibration after replacing and/or
reassembling any parts which require the replacement of the MA board at the
same time.

3.7.2 Preparation

1. Be sure that all feet of the projector for which you perform this
calibration are completely retracted.
2. Place the projector on an even and stable place such as on the top of a
table.

3.7.3 Procedure

2. Check if the Power LED flashes blue, then lights blue.
3. After the LED lights up, long-press the [Home] button and the [Source
Search] button together for five seconds or more.
