Constructors should refer to the Component Overlays along with,
the Bill of Materials for the current value of all components, and
the General Construction Notes for general PCB assembly guidelines.

Refer to the diagram below when reading the following assembly notes.

1. Assemble the 1x Jack Carrier PCB (3D Model)

2. Populate the main board with all components except J101, S101, S102, P101, S301, S302 and LCD1

3. Remove the protective film from the LCD.

4. Fit the 4x M3x20mm bolts to the front panel using the 4x M3x4mm spacers.

5. Carefully slide the LCD on to the bolts and secure using the 4x M3x6mm bolts. Make sure the PCB header is at the top of the module

6. Position all the remaining items on to the board but do not solder.

7. The 2 switches S101 and S102 should each have 1x nut, an anti-rotation washer and a shakeproof washer placed on them before mounting to the panel.

8. Carefully offer the board up to the front panel being careful when inserting the header from the LCD module.

9. With everything in position secure the main board to the front panel using the 4x M3 Nuts.

10. Finger tighten nuts on the switches S101 and S102 and the jack J101.

11. Solder all components in to place ensuring that the pot shaft remains central to the front panel hole while being soldered

12. Similarly, check the operation of the 2x pushbutton switches before soldering

As of July 31st 2020 our ED701 kits are shipping with a WHITE-ON-BLUE display. The software needs to recognise the display type so a wire link must be fitted between U301_4 and C301_2 as shown on the Component Side Overlay if using the original BLACK-ON-WHITE display.
