Scattare una fotografia:
- Punta la telecamera: Guarda attraverso il viewmirino per comporre lo scatto.
- Messa a fuoco automatica: The Sonar OneStep model features automatic sonar autofocus. The camera will emit a sound wave to determine the distance to your subject and adjust focus accordingly.
- Manual Focus (Optional): For precise control or in situations where autofocus struggles, you can manually adjust the focus wheel located near the lens.
- Adjust Exposure (Lighten/Darken Wheel): The camera has an automatic exposure system. If you wish to lighten or darken the image, use the exposure compensation wheel (often marked with a light/dark symbol) located on the front of the camera. Turning it towards the white symbol will lighten the image, and towards the black symbol will darken it.
- Premere il pulsante di scatto: Once focused and composed, press the red shutter button. The camera will expose the film and eject the print.
- Protect the Print: Immediately after ejection, protect the developing print from light by placing it face down or in a dark place for the first few minutes of development.

Using a Flashbar:
For low-light conditions, insert a compatible Flashbar into the slot on top of the camera. The camera will automatically detect the Flashbar and use it for illumination.
4. Manutenzione e cura
- Pulizia della lente: Utilizzare un panno morbido e privo di lanugine, specificamente progettato per gli obiettivi delle fotocamere, per pulire delicatamente l'obiettivo. Evitare materiali abrasivi o sostanze chimiche aggressive.
- Rulli di pulizia: Periodically inspect the film rollers (visible when the film door is open) for any residue. Clean them gently with a damp cloth to ensure even film development.
- Magazzinaggio: When not in use, fold the camera into its compact form and store it in a cool, dry place away from direct sunlight and extreme temperatures.
- Batteria: The camera's internal battery is part of the film pack. Always use fresh film packs to ensure optimal camera performance.
