5. Setup
- Mounting the Monolight: Attach the monolight to a compatible light stand using the integrated mounting bracket. Secure it firmly by tightening the adjustment knob.
- Attaching Light Modifiers: If using a light modifier (e.g., softbox, reflector), align its Bowens mount with the monolight's mount and twist to lock it into place.
- Connecting Power: Insert the 5m (16.5') grounded power cord into the power input socket on the monolight and then into a suitable electrical outlet.
- Connecting Sync Cord (Optional): For wired synchronization, connect the 10m (33') sync cord to the sync port on the monolight and to your camera's PC sync terminal or a compatible trigger.
- Protective Cap: Remove the protective cap from the flash tube and modeling lamp before operation. Always replace it when transporting or storing the unit.
6. Operating Instructions
- Power On/Off: Locate the power switch on the unit and switch it to the 'ON' position. The modeling lamp may illuminate, and the unit will begin to charge.
- Adjusting Flash Power: Use the power adjustment dial or buttons (if present) to set the desired flash output level. Refer to the unit's display or indicators for the current power setting.
- Modeling Lamp Control: The 150W halogen modeling lamp can be turned on or off independently. It provides continuous light to help visualize lighting effects before the flash fires.
- Slave Mode: The monolight can act as a slave unit. When enabled, it will optically trigger when it detects a flash from another strobe or camera's built-in flash. Ensure the slave sensor is unobstructed.
- Test Flash: Press the 'Test' button to fire a test flash and verify the power setting and light output.
- Cool Down: After extended use, especially with the modeling light on, allow the unit to cool down with the fan running before powering it off completely. This helps prolong the life of the bulbs and internal components.
7. Maintenance
- Cleaning: Gently wipe the exterior of the monolight with a soft, dry cloth. For the flash tube and modeling lamp, use a clean, lint-free cloth. If the flash tube is touched, clean it with rubbing alcohol to remove oils, which can create hot spots and reduce its lifespan.
- Modeling Lamp Replacement: The 150W halogen modeling lamp is user-replaceable. Ensure the unit is unplugged and cool before carefully unscrewing the old lamp and screwing in a new one.
- Flash Tube Replacement: The 400 WS flash tube in this model is generally not designed for user replacement. If the flash tube fails, professional service is recommended. Attempting to replace it yourself may void the warranty or damage the unit.
- Storage: Store the monolight in a dry, dust-free environment. Always attach the protective cap when not in use.
