6. Operating Instructions

The Profoto ProHead Plus operates in conjunction with a Profoto power pack, which controls flash duration, power output, and other settings.

6.1. Adjusting Light Output

Light output is primarily controlled via the connected Profoto power pack. The markings on the flash head (e.g., 10, 9, 8, 7, 6, 5, 4) typically correspond to the zoom position of the flash tube relative to the reflector, allowing for beam angle adjustment when using compatible light shaping tools like the Zoom Reflector.

• Zoom Reflector Adjustment: To adjust the beam angle, slide the Zoom Reflector forward or backward on the flash head. The numerical scale on the flash head indicates the relative position, influencing the spread of light.

6.2. Modeling Lamp

The modeling lamp provides continuous light for previewing lighting effects. Its intensity is controlled by the power pack. Refer to your power pack's manual for specific modeling lamp settings.

6.3. Fan Operation

The integrated fan automatically activates to maintain optimal operating temperature, especially during rapid firing or extended use of the modeling lamp. Ensure the fan vents are clear of obstructions.

6.4. Using Light Shaping Tools

The Profoto ProHead Plus is compatible with a wide range of Profoto light shaping tools. To attach a light shaping tool, align it with the front of the flash head and secure it according to the tool's specific instructions. Always ensure the unit is cool before changing accessories.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your flash head.

• Cleaning: Disconnect the flash head from the power pack before cleaning. Use a soft, dry cloth to wipe the exterior. For the glass cover and flash tube, use a lens cleaning solution and a microfiber cloth. Avoid abrasive cleaners.
• Flash Tube Replacement: The heavy-duty quartz flash tube has a long lifespan, but eventually requires replacement. This procedure should only be performed by qualified personnel or a Profoto service center. If you must replace it yourself, ensure the power pack is off and unplugged, and allow ample time for capacitors to discharge. Carefully remove the old tube and install the new one, ensuring proper alignment and connection.
• Storage: Store the flash head in a dry, dust-free environment when not in use. Use protective caps and covers to prevent damage.
