3.8 Touchscreen sensor (-T models)

The touchscreen sensor may eventually wear out after exhaustive and prolonged use. Before you replace it, you must slide out the work drawer.

1.Switch off the power, and detach the main power cord.

2.Detach the work drawer and cover from the AWS-8248 unit. (See Fig. 2-1.)

3.Slide the work drawer out as far as it will go.

4.Remove the operating membrane keypad connector protective bracket, and carefully pull off the two operating membrane keypad cables.

5.Detach the external keyboard cable from the keyboard translator.

6.Detach the four waterproof sponges.

7.Unscrew the 12 screws around the perimeter of the front panel which hold the panel to the main chassis.

8.Separate the front panel from the chassis, the touchscreen cable from the touchscreen sensor, and the function keypad cable from the function keypad. (See Fig. 3-11.)

9.Detach the four shock-absorbing sponges, and detach the touch- screen sensor. Remove any residual adhesive from the aluminium panel.

10.Apply new adhesive, and attach the touchscreen sensor to the alu- minium panel. Make sure that the sensor is oriented correctly.
