Disassembly procedure
Disconnect power before disassembling.
1. Place the ATAC with the front panel facing down. In this way the buttons will stay
in the front panel when the boards are removed, see fig. 1.
2. Loosen four screws at the bottom, one in each corner
3. Remove the cover.
4. Remove the protection plastic in one corner. The plastic protects against electric
shock from the terminals for backlight.
5. Remove four spacers, one in each corner.
6. Lift up gently the boards, make sure the front panel stays on the table. DO
NOT turn around the front panel, all the buttons are loose!
7. To remove the switch board (PC7002-x); loosen five screws and solder out the
pins at J2.
8. To remove the display; loosen four screws and solder out the two wires for
backlight.
Note: The software cannot run without the display. An extension cable is
therefore very useful for doing trouble shooting while the unit is running.
Disassembling gives access to do measurements at all components.
WARNING: Do not touch the terminals at JP1. High voltage for backlight!
