2. BATTERY CHECKING
If the green-colored battery check lamp lights up when the battery check
button is depressed, the battery is loaded properly and there is sufficient
power for electronically-con trolled operations.
* If the lamp does not light up ( 1 ) the battery is not loaded properly or
(2) the battery is completely drained and should be exchanged.
A. The film back consists of a film holder and a film back frame, with
exclusive film holders supplied for 120 and 220 roll films.
The film holder has an insert or frame for loading film, as well as a built-
in film winding mechanism.
B. The film back frame, on the other hand, consists of a base with a dark
slide slit and a back cover with a film type indicator frame. The film
back frame completely encloses the film holder and shields it from
outside light (see page 24), as well as connecting it to the camera body.
