2.5.4 Membrane Switch Panel and Display
Switch ON the controller and check the Liquid Crystal Display (LCD) for
sharpness, legibility and brightness. If the display appears dim or segments
are missing, dismantle the display assembly and clean the contacts to the LCD
(see Section 4.13). If after reassembling the controller the display is still
defective, then replace the
zebra elastomer and the LCD bezel (snap fit) only.
Use the following tests to check that the buttons on the membrane switch
panel are working effectively. If a button has to be pressed hard or more than
once in order to get a response, then replace the switch panel (see Section 4.5).
