| Cleaning Switches |
Do not attempt this at home... Disassembling the push button switches can be incredibly stupid. I have
screwed up a few of these learning how to do this properly and reliably. Those little copper contact are
loose and fall freely from the shaft. Apply a small amount of Doxit to them and they cling a bit. They
must align perfectly with the contact rails in the body for reassembly, or they will bend and jam. And
they are soooo... small and delicate.
I only disassemble these if there is an obvious problem with the switch, such as spring tension or
operational issues. This unit had soft springs (compressed over time). So I gave them a slight stretch
and applied DeoxIT to the contacts.

The rest of the switches all get treated with DeoxIt. The volume control needs special
handling as it is a sealed unit.

The Volume control is sealed.
Under the label on the back is a
clip that is pressed on. If you have
a dirty or oxidized volume control,
the easiest way to get DeoxIt into it
is to drill access holes. A hand drill
works great for this.

You only need to drill access holes
in the second and third layers. The
front layer contains nothing but the
stepper. Don't over-shoot the hole
when the drill breaks through.

The 4th and 5th levels can be
accessed from the bottom.
