• To clean dirt on the surface, use a dry, soft cloth or a cloth immersed
in ethyl alcohol.
• Check that the housing does not induce any stress to the touch
panel.
• Be careful not to touch the touch panel with tools.
• The heat seal section is easily disconnected. Be careful not to apply
any stress to the heat seal section when installing.
