1. Sissejuhatus
The Vivitar 283 Electronic Flash is designed to provide versatile and reliable illumination for various photographic needs. This manual provides detailed instructions for the proper setup, operation, and maintenance of your flash unit.
Key features of the Vivitar 283 include:
- Vertical Bounce Flash: Allows for softer, more diffused lighting by directing the flash head upwards.
- Auto Thyristor Circuitry: Ensures fast recycling times and an increased number of flashes per battery set.
- Remote Sensor Capability: Enables off-camera flash synchronization.
- Multiple Automatic f/stop Settings: Provides flexibility for various exposure conditions.
- Illuminated Calculator Dial: Assists in determining correct exposure settings.
- Autocheck and Sufficient-Light Indicator: Confirms proper flash exposure.

2. Seadistamine
2.1 Aku paigaldamine
The Vivitar 283 flash requires four (4) AA batteries for operation. An optional Vivitar SB-4 110-volt AC adapter can also be used.
- Locate the battery compartment cover, typically on the side or back of the flash unit.
- Sahtli avamiseks libistage või avage kaas.
- Insert four AA batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
- Sulgege akupesa kaas kindlalt.

2.2 Välgu paigaldamine
The Vivitar 283 is designed to mount onto a camera's hot shoe or a flash bracket.

- Secure the flash by tightening the locking mechanism on the mounting foot.
Important Note on Trigger Voltage:
The Vivitar 283 flash units, especially older models, may have a high trigger voltage (potentially over 300 volts). This high voltage can damage the sensitive electronics of modern digital cameras. It is strongly recommended to verify the trigger voltage of your specific unit using a voltmeter before mounting it directly onto a digital camera. For digital cameras, consider using an external trigger or a voltage protector if the flash unit's trigger voltage is high. Using the flash off-camera with a compatible trigger is generally safer.
3. Kasutusjuhised
3.1 Powering On and Recycling
- Keera toitelüliti asendisse „ON”.
- Allow the flash to recycle. The 'Ready' light will illuminate when the flash is fully charged and ready to fire.
3.2 Setting Automatic Exposure
The Vivitar 283 features an Auto Thyristor system with four automatic f/stop settings. Use the illuminated calculator dial to select the appropriate setting based on film speed (ISO) and desired aperture.

- Set your camera's shutter speed to the flash synchronization speed (typically 1/60s or 1/125s, refer to your camera manual).
- Adjust the calculator dial on the flash to match your film's ISO speed.
- Select one of the four automatic f/stop settings (e.g., f/4, f/5.6, f/8, f/11) on the flash and set your camera's aperture to the corresponding value.
- The flash's auto sensor will measure the light reflected from the subject and cut off the flash duration when sufficient light has been emitted.
- The 'Sufficient-Light Indicator' will light up after the flash fires if the exposure was adequate.
3.3 Bounce Flash Operation
For softer, more natural lighting, the flash head can be tilted upwards to bounce light off a ceiling or wall.

- Gently tilt the flash head upwards to the desired angle.
- Ensure the surface you are bouncing off (ceiling, wall) is neutral in color to avoid color casts.
- Adjust exposure settings as needed, as bouncing light can reduce its intensity.
3.4 Remote Sensor Use
The Vivitar 283 can be used off-camera with its remote sensor capability. This allows for more creative lighting setups.
- Connect a compatible remote sync cord to the flash's remote sensor port.
- Position the flash off-camera as desired.
- Ensure the remote sensor on the flash has a clear line of sight to the main flash or trigger.
4. Hooldus
4.1 Puhastamine
- Use a soft, dry cloth to clean the exterior of the flash unit.
- Kangekaelsete plekkide puhul kergelt dampNiisutage lappi veega või õrna puhastuslahusega ja seejärel pühkige kohe kuivaks.
- Do not use abrasive cleaners or solvents, as these can damage the finish or electronic components.
- Keep the flash tube and sensor clean for optimal performance. Use a lens cleaning cloth for these delicate areas.
4.2 Aku hooldus
- Always remove batteries from the flash unit if it will not be used for an extended period (e.g., several weeks or months).
- Inspect the battery compartment regularly for any signs of corrosion. If corrosion is present, clean it carefully with a cotton swab dipped in white vinegar or lemon juice, then wipe dry. Ensure no liquid remains.
- Use fresh, high-quality AA batteries for best performance and to prevent leakage.
4.3 Säilitamine
- Hoidke välklampi jahedas ja kuivas kohas, eemal otsesest päikesevalgusest ja äärmuslikest temperatuuridest.
- Protect the flash from dust and moisture, ideally in a camera bag or protective case.
5. Veaotsing
| Probleem | Võimalik põhjus | Lahendus |
|---|---|---|
| Välklamp ei sütti | No power; Batteries drained or incorrectly inserted; Flash not fully recycled; Camera sync issue. | Check batteries and polarity; Replace batteries; Wait for 'Ready' light; Ensure camera shutter speed is at sync speed. |
| Aeglane ringlusaeg | Low battery power; Old batteries. | Asendage värskete kvaliteetsete patareidega. |
| Inconsistent exposure | Incorrect f/stop setting; Auto sensor obstructed; Subject too far/close. | Verify f/stop and ISO settings; Ensure sensor is clear; Adjust distance or use manual mode if applicable. |
| Akupesa korrosioon | Batteries left in unit for too long; Battery leakage. | Remove batteries when not in use; Clean corrosion as described in Maintenance section. |
| Flash damages camera | High trigger voltage. | Always check trigger voltage before mounting on digital cameras. Use voltage protector or off-camera trigger if voltage on kõrge. |
