9. To remove the circuit board, desolder the two leads to the slide switch and
lift the circuit board and cable clear.
NOTE
. Observe the routing of the switch leads through the circuit board shield. It
is important that the leads be routed in the same way when the board is
replaced.
10. Before reassembling the probe, be sure that the gap between the stationary
and moveable core pieces is clean. If necessary, clean the core pieces using a
lint-free cloth and water or isopropyl alcohol (IPA). Also, clean the contacts
of the slide switch, if necessary.
11. Should the plastic slide assembly require lubrication, sparingly apply
silicone-based grease to the parts.
12. Probe reassembly is the reverse of steps 1 through 9. You may need to
squeeze the handle slightly to align the gear teeth with the slide rack.
