Caring for the Scope
Do not attempt to lubricate the scope. It is sealed
from within using O rings and special compounds.
All seals are permanent and require no
maintenance.
Use a lens brush to remove surface dust and loose
particles. To clean a lens, moisten it with lens
cleaning solution and wipe it with a clean cloth or
lens tissue.
The adjustment screws are permanently lubricated;
do not attempt to lubricate them. Keep the cover
screws and sealing washers in place except when
the scope is being aligned.
Checking the Display Screen
The instrument provides a method of verifying the
display integrity. You can do that as described in
“Powering On and Off’ and in “Testing Display
Integrity,” earlier in this manual.
Resetting Factory Option Defaults
The instrument remembers option settings even with
the power turned off. To return options to their
factory defaults, use the procedure in Restoring the
Default Configuration, earlier in this manual.
