5. Operating Instructions

5.1 Powering On/Off

Flip the Power Switch to the "ON" position to power on the monolight. The display will illuminate. Flip to "OFF" to power down.

5.2 Adjusting Flash Power

Use the Up and Down buttons to adjust the flash output power. The power level is displayed on the screen, ranging from 7.0 (1/8th power) to 10 (1/1 power). The unit will emit a buzzing sound when fully recycled and ready to flash (if buzzing is enabled).

5.3 Modelling Lamp Operation

Press the MODEL button to turn the 150W modeling lamp on or off. Use the Up and Down buttons to adjust its brightness (L1-L9). The modeling lamp automatically extinguishes when the flash fires.

Important: The modeling lamp can become very hot. For safety, it is recommended not to use the modeling lamp for more than 10 minutes continuously, especially with flammable accessories. Allow it to cool down for at least 10 minutes before continued use.

5.4 Flash Modes (S1/S2 Optical Control, Sync Socket)

The S101-300W supports multiple flash triggering modes:

• Manual Control: Trigger the flash directly using the TEST button or a compatible trigger connected via the sync socket.
• S1 Mode (Optical Slave): In S1 mode, the monolight acts as a slave flash. It will trigger simultaneously with the first flash from a master flash unit. This is suitable for manual flash systems.
• S2 Mode (Pre-flash Cancel Slave): In S2 mode, the monolight also acts as a slave but ignores the pre-flash from a master flash unit (common in TTL systems). It will trigger on the second flash.
• 3.5mm Sync Socket: Connect a wired sync cable from your camera or flash trigger to the 3.5mm Sync Socket for reliable wired synchronization.
