The HMI-640S is of a modular design so that it is convenient for users to maintain or service its internal components. This chapter will describe the disassembling process for the machine. The Service CD bundled in the HMI-640S package provides even more details for your reference.

3.1 Removing the Front/Rear Panel

You need only to remove the front panel of your HMI-640S to replace its LCD or backlight. To remove the front panel, first verify the power source to the HMI-640S has been disconnected. Next, remove the two screws found on the underside of the front panel. Pinch a corner of the front panel up with one hand, and then pull the other corner of the front panel firmly outward to remove the front panel.
