CARE AND HANDLING
Your
Photomic
FT
N
Finder is
ruggedly
constructed.
However,
it
deserves the
same care you
would give any
precision instrument.
Follow
the simple precautions
given
below
and
the
Photomic FT
N
will
give years
of dependable
service.
•
Store
the
finder
in
a case
to keep ou t dust.
Avoid storing
it in places liable to
excessive
heat,
cold
or
dampness.
•
Attach a prism guard
when
storing
the
finder separately.
•
To
insure most dependable
service,
clean the battery
contact
surfaces periodically
with
a
rough clo th.
•
Avoid
fingerprints and
dust particles
on
the prism
surface.
•
Brush
away grit
or dust with a
soft
brush
or
use
a
rubber syringe. Do not
use cloth
or
ordinary
tissue.
•
If
smudges or fingermarks
persist, use tissue with
a
professionally recommended lens cleaner
very sparingly.
Wipe with a
circular
motion
and gentle
pressure.
Even
an
approved
cleaner
can cause damage
if it
seeps
into the prism mount
.
•
To
insure that the
exposure
meter will operate properly
when
needed,
it
should
be
checked periodically
.
Make a few trial
exposures
before leaving for a holiday.
Allow at
least
two
or
three
weeks'
time for processing the
test film and
making
any
needed repairs
or
adjustment. This simple
precaution may
save a valuable
holiday record
which would
other-
wise
be
lost.
