PRELIMINARY CHECKOUT

Inspect the camera for missing or broken parts. Replace parts as needed.
2.
Remove the batteries from the camera. Examine the contact area for signs of
corrosion. Clean any corrosion on the battery contacts and discard any corroded
batteries.
3.
Using a tester with a one-ohm load, test the batteries. Discard any battery that
reads less than 1.2 volts.

Install known good batteries into the camera. Cover the photocell completely to
block any light, look into the lens to observe the shutter blades, and press the

uncovered. If the shutter does not stay open, see the Troubleshooting section
"Opening and Closing Blades Close Together."
