Quartz Date Back E Technical Back E / Interface Unit TB / Keyboard Unit
E
The Quartz Date Back E is a fully automatic data back which imprints data on the film.
1. Auto date up through the year 2029. (automatic compensation for leap years and long/short months)
2. Auto digital clock mode (Day/Hour/Minutes) with 24 hour display.
3. Arbitrary 6-digit numbers
4. Frame counter number from Fc 0001 through 9999.
As the name "Technical" suggests, the Technical Back E not only imprints the data and arbitrary comments (up
to 30 digits) on film but memorizes shooting data such as shutter speed, aperture value, lens focal length and
film speed.
· When the Technical Back E is connected to a personal computer through the Interface Unit TB, it is also
possible to command the camera from a computer, etc. (The Interface Unit TB is sold in both MSX and IBM
computer models, but product availability may vary from area to area.)
· With the Keyboard Unit E, comments can be imprinted in English, French, German and Spanish.
