If, by accident, you happen to pull one of the posts
from its socket DO NOT PANIC! Remove the Rub-
ber Boot from the post VERY carefully, then, with
a toothpick or the allen wrench you received with
your adapter, gently tuck the Rubber Boot back
into the mounting hole. Then, carefully re-insert
the Aluminum Post into the rubber boot. DO NOT
attempt to force the Aluminum Post with Rubber
Boot attached into the mounting hole for risk of
damaging the boot and Ground Glass (GG) mount-
ing system. Take your time and be very careful.

Cleaning The System:
We try our best to ship each unit free of dust in the
Optical Path. However, the Magic of Dust Particles
is always surprising. In which case you may need
to clean the optical path, refer to the steps listed
below: NOTE: If the dust moves when the unit is
operating it will more than likely be located on the
Ground Glass (GG) and you will only need to per-
form steps 1 – 3.
1.
Open the front tube of the Letus35 Mini
35mm DOF Adapter by removing the four
(4) screws and VERY carefully remove the
tube. You will see the Ground Glass (GG).
2.
Clean the ground glass if you find the dust
there. Only go on to next step if the speck
is stationary when the ground glass is ro-
tating, if it is clean, put the tube back on. If
not, continue to step 3.
3.
Clean the top surface of the condenser
(the glass right below the ground glass). If
the speck goes away, you are done clean-
ing, put the tube back on. If not, continue
to step 4.
4.
Through the 2 holes on the ground glass
holder, unscrew the 2 Allen screws hold-
ing the enclosure cap to the body of the
adapter. Use a flat object to pry off the en-
closure cap from the body of the adapter.
5.
Clean the other side of the condenser.
