Assembly Iambic Key

Iambic key assembly instructions

1. Separate the sections of the panel and clean up the connection points (two of the pannels are for the sounder unit and are not needed for this build)
2. check and trim any mechanical connections
   1. Remove radi on back of paddle PCB sections where the mounting lugs connect
   2. provide a slight chamfer on the edges of the mounting lugs on paddles
   3. ensure audio jack and switch fit in holes and adjust if required
3. Solder SMT components on back of front panel
4. Solder paddles to the PCB.
5. install the audio jack and switch into the front panel.
6. Solder the audio jack to the points on the back of the panel and the switch to the vcc point.
7. Solder the battery pack into the unit with the switch in series (you may wish to test fit into the housing to get the correct cable lengths).
8. Test the key functions.
9. Remove the case PCB mounts (a razor saw works well) that collide with the switch and audio jack.
10. Install PCB and battery compartment into top of case (optionally glue a ribbon under the battery compartment to aid in battery removal).
11. Place bottom of case over assembly and screw down.

Optional modifications

• if the front panel moves too much consider gluing it to the top of the case.
• if the key is to light and moves around you can add additional weight on the bottom of the case and/or add some rubber feet to control movement.
