Control Panel Removal
Control Panel Removal
1 Lay the EDGE System on its top exposing the bottom section and remove the system battery.
2 Remove the 8 screws from the Bottom Enclosure of the system using a #2 Phillips screwdriver per Figure 6.1.
3 Remove the 2 screws in the EDGE Main Frame securing the Top Enclosure per Figure 6.2.
Use caution when removing the Top Enclosure area under the Display. This area is retained with an adhesive strip
and using too much force will break the Top Enclosure requiring replacement. Carefully slide a small flat bladed
screwdriver from one side to the other to release the tape.
Caution:
When lifting the front edge of the Control Panel away from the Main Frame, lift under the Control Panel board. Do
not lift by the rubber membrane. This can easily become detached from the Control Panel board and cannot be
refastened!
4 Turn the system over, fully open the Display Assembly, and remove the EDGE Top Enclosure per Figure 6.3.
5 Remove the ten perimeter screws holding the Control Panel, carefully lift, and slide forward. Refer to Figure 6.4.
6 Expose the underside of the Control Panel by lifting from the front EDGE and hinge via the top EDGE toward
the LCD display.
7 Remove J6 “LCD OUT”, J8 “BL OUT”, J5 “LCD IN”, and J7 “BL IN” cables by gently pulling away from their sockets.
8 Remove the J4 “SPI” and J9 “GAIN” ribbon cables after unlocking the dark gray retainer on both sockets as per
Figure 6.6.
9 Lift off the loose and un-tethered Control Panel assembly from the EDGE frame.
