CARE AND HANDING
Your Photomic FTN Finder is ruggedly constructed. However, it deserves the same care you would give any preci-
sion instrument. Follow the simple precautions given below and the Photomic FTN will give years of dependable
service.
• Store the finder in a case to keep out dust. Avoid storing it in places liable to excessive heat,
cold or dampness.
• Attach a prism guard when storing the fnder separately.
• To insure most dependable service, clean the battery contact surfaces periodically with a
rough cloth.
• 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 otherwise be lost.
