here is the user manual for KLH R5100

Welcome to Fixya.

This is where you can download all necessary tools/software for your camera :

Nikon Support Page

For the imaging tools, just look under "Software" tab. For the complete user's manual, look it up under "Support" tab.

Thank you for using Fixya.

You can get one straight from Nikon's website. They call it a 'user's manual' rather than an 'owner's manual' which could be why you didn't find it. Anyway go here, and choose your printable version (as an owner) or a non-printable one.

The Nikon F55 is the exact same camera....the manual is available here:

ftp://FQL2V2NM:[email protected]/Manuals/YS301T4P/F55rmen.pdf

Be patient - it takes a minute to load, then you can click the Save from File menu.

Please take the time to rate my response thanks.
