Mounting Surface Warping - Pioneer PDP-433CMX Technical Manual

[433CMX/433MXE]

3.3.4 Mounting surface warping

The display section incorporates glass. Before mounting the product, using hardware other than that provided by
Pioneer, perform the following to confirm that the display is free from warps exceeding 1 mm*.
* Regarding the 1mm limit
The frame of the display may have a warp of up to 3mm. If the total warp (the warp of the frame plus the warp of the
mount surface) exceeds 4mm then the glass in the display may be put under excessive stress. In order to ensure that
the total warp is less than 4mm, you should make sure that the warp of the mount surface is less than 1mm.
1 Referring to the illustration below, diagonally extend string of maximum φ 0.1-mm diameter through the bolt
mount openings. Strings thus arranged should be completely free of slack.
2 Measure the clearance (L) between the strings at their point of intersection.
Distortion is expressed by: [Distortion] = L × 2.
3 If L is found to be 0, pass the strings through the other bolt mount openings and repeat the measurements. Any
value of L greater than 0 indicates the presence of distortion. If the measured value in both cases is 0, the
distortion is negligible.
