Warranty Information
No warranty information is available in this manual.
To operate the PETRI EF 35, press the red button on the camera and turn the diaphragm ring until both red lights in the viewfinder are illuminated. Pay attention to the following: avoid pressing the red button for too long to conserve battery. When photographing landscapes, point the camera slightly downwards to frame approximately 2/3 of the landscape and 1/3 of the sky. If only the right red light illuminates with the largest aperture (f/2.8), it indicates insufficient light for a properly exposed picture, requiring the use of the electronic flash.
Troubleshooting and error codes
| Problem | Possible Cause | Solution |
|---|---|---|
| Blurry or double exposures | Camera not held firmly while releasing the button. | Hold camera firmly, practice pressing the button softly and resolutely, hold breath, press gently. |
| Under-exposure (only right red light on, largest aperture) | Insufficient light. | Use electronic flash. |
