• POWER унтраалга: Turns the flash unit on or off.
• FILM SPEED / ISO Dial: Sets the film speed or ISO sensitivity.
• AUTOMATIC / MANUAL Selector: Switches between automatic and manual flash modes.
• f/STOP / RANGE Dial: In automatic mode, this sets the aperture and corresponding flash range. In manual mode, it may indicate guide number related settings.
• AUTO OK Indicator: Lights up when the flash has achieved correct exposure in automatic mode.
• READY / TEST Button: Lights up when the flash is fully charged and ready to fire. Pressing it fires a test flash.
• C/R Switch: Likely a control for specific camera compatibility or mode.
• TTL A1/A2/M Selector: Selects between different automatic (A1, A2) or manual (M) modes, potentially related to TTL (Through-The-Lens) metering if supported by the camera.

4.2. Automatic Mode Operation

In automatic mode, the flash's built-in thyristor sensor measures the light reflected from the subject and automatically cuts off the flash output when sufficient light has been provided for correct exposure.

1. Attach the flash to your camera and power on both devices.
2. -г тохируулах AUTOMATIC / MANUAL selector to "AUTOMATIC".
3. -г тохируулах FILM SPEED / ISO dial to match your camera's ISO setting.
4. Select an appropriate f/stop on the flash using the f/STOP / RANGE dial. This will also indicate the effective flash range. Set your camera's aperture to match this f/stop.
5. -г хүлээнэ үү READY / TEST indicator to light up, signifying the flash is charged.
6. Take your photograph. The AUTO OK indicator will light briefly after the flash fires if the exposure was correct.

4.3. Гарын авлагын горимын ажиллагаа

In manual mode, the flash fires at full power, and exposure is controlled by your camera's aperture and shutter speed settings.

1. Attach the flash to your camera and power on both devices.
2. -г тохируулах AUTOMATIC / MANUAL selector to "MANUAL".
3. Consult the flash's guide number (usually found in a separate table or on the unit itself) to determine the correct aperture for a given distance and ISO.
4. Set your camera's aperture and shutter speed accordingly.
5. -г хүлээнэ үү READY / TEST indicator to light up.
6. Take your photograph.

4.4. Үсрэлтийн гэрэл

The Vivitar 550 FD Speedlite supports bounce flash, allowing you to direct the light indirectly off a ceiling or wall for softer, more natural illumination.

1. Gently tilt the flash head upwards or to the side to bounce the light.
2. Adjust camera settings as needed for the increased light path and diffusion.
