Jim, this begs the question as to why a small disabling switch was not 
installed in the camera moduals of both the regular and magnification lens, 
thus negating the expense of the calculator lens.

Doug: that water under the bridge--maybe it had fish in it!

The part you move across the type is called the camera unit.  It comes in
two parts, a retina module and a lens unit.  The two units can be snapped
apart by push in and twisting.  On the part of the retina module that was
inside of the lens module are two contacts that mate with corresponding
contacts inside of the lens module.  These contacts conduct power to the
lamps in the lens module.  You need to break this circuit to turn off the
lamps.  You can do this by placing a small thin non conductor, such as a
small piece of tape, on one of the contacts and re-assembling the retina
module and lens unit.
