This was typed and scanned in from the Yashica manual.   I fixed one or two minor spelling and grammatical errors, but that's it.   In some places the phrasing is unclear and sometimes the references almost seem to be circular.   I didn't write it.   On top of that, I haven't even had occasion to open my TL Electro-X yet, so I probably don't have the answers to any questions you may have.   Most of this does seem to make sense after reading some of the first Tomosy book though.

Foreward

This manual contains matters necessary for repair and servicing of the Yashica TL Electro-X.

The Yashica TL Electro-X incorporates the following functional features which make it completely different from other focal shutter single-lens reflex cameras:

1. Thru-the-lens exposure readout system which does not require an exposure meter and provides measurement of the correct exposure at stopped-down aperture through preselection of either the lens aperture or shutter speed.
2. Electronic-controlled focal plane shutter affording an infinite range of intermediate shutter speeds (and providing faithful function at 1/1000 sec. even when battery power is exhausted).

Its exposure readout and electronic shutter systems follow the pattern of those featured in the Lynx-5000E (14E) and Electro 35, and their merits are outlined in their respective repair manuals. Generally speaking, therefore, the Yashica TL Electro-X can be said to be an equipment which offer all advantanges of the above-mentioned cameras.
