Without looking into the
eyepieces, set the minimum
magnication (6.4×).
Turn the dioptric correction on
the eyepieces to "+5".
Look into the eyepieces. Ro-
tate each eyepiece individual-
ly clockwise, in the "–5" direc-
tion, until each eye sees the
writing in sharp focus.
Turn out the eyecups to the
desired distance.
INFO
The writing should now re-
main sharp when you change
the magnication.
If it does not, repeat the
procedure.
Set maximum magnication
(40×).
