xRemove the back side plastic housing of your CRT monitor.
xDischarge the CRT tube from the front bezel (usually there are 4
screws on the 4 corners need to be released).
xCheck if the electronic board needs to be removed or not.
xVerify the fit position on the CRT tube for the touchscreen.

the CRT. You can use the double side high tack adhesive tape (as
3M) to attach the touch sensor onto the CRT display
xAfter this process, check the space between the touch
sensor and the front bezel. If the space is not enough, you may
need to add rubber spacers between the touch sensor and the front
bezel ( the 4 corners on which the CRT and the front bezel is
