Polaroid SX70 manual Loading the Film pack, Starting the Automatic Mechanism

When the camera is fully opened, the interlock switch (S6), located at the left rear corner of the mirror cover, is closed and the battery is connected to the camera electrical circuit.

2. Loading the Film pack

The front coverlatchis located on the right side of the camera just inside the rim of the bottom cover assembly. Pressing down on this yellow latch releases the front cover which drops down to expose the film chamber. With the cover open, a film pack can be inserted or an exhausted pack can be removed.

A fresh film pack is loaded into the film chamber observing color coding (Figure 1-5). Under certain circunstances a partially used pack could be inserted, but this action will cause some deviation in the normal counting sequence.

The battery is a part of each film pack, and the two exposed terminals on the pack engage two contacts within the film chamber as the pack is inserted.

3. Starting the Automatic Mechanism

With the film pack in place, the front cover can be closed. It must be fully closed and latched.
