switches horizontally and vertically.
• Press the touch switches with a pressure of 30 N max.
Note
• Do not press the touch switches when the backlight is not lit or when there is no display.
• Check system safety before pressing the touch switches.
• Inputs may not be recognized if the touch switches are pressed in rapid succession. Check

Reference
When the positions of multiple touch switches are set as shown in the example and
three switches are pressed simultaneously, the touch switches will malfunction due to
structural characteristics.
Position the touch switches carefully. In the example shown below, switches have
been created in positions A and B, and at points C and D, where the vertical and hori-
zontal lines through A and B intersect.
