Setup

Operation
- Power On/Off: Flip the power switch on the rear panel to turn the unit on or off.
- Adjusting Flash Power: Use the control dial on the rear panel to adjust the flash output from 1/1 (full power) to 1/32 in 50 precise steps. The current power setting will be displayed on the LCD screen.
- Modeling Lamp Control: Press the modeling lamp button to cycle through different modes: On, Off, or Proportional (brightness adjusts with flash power). The 150W modeling lamp's brightness can be adjusted from 5% to 100%.
- Test Flash: Press the test flash button to manually fire the strobe and check the light output.
- Wireless X System: The MS300 features a built-in 2.4 GHz Godox Wireless X System. Use compatible Godox wireless triggers (e.g., X1, XT16, XPro, X2) to wirelessly control the strobe's power, modeling light, and triggering. The system supports 32 radio channels and 16 groups. Refer to your wireless trigger's manual for specific pairing and operation instructions.
- Group and Channel Selection: Press the GR/CH button to select the desired group and channel for wireless communication. Ensure these settings match your wireless trigger.
- S1/S2 Optical Slave Modes: Press the S1/S2 button to activate optical slave modes.
- S1 Mode: The strobe will fire in response to a single flash from another strobe.
- S2 Mode (Anti-Preflash): The strobe will ignore the pre-flash from a camera's built-in flash and fire on the main flash. This function provides synchronization with cameras capable of firing a preflash.
- Sound Prompt: Press the sound button to enable or disable the audible beep that indicates when the strobe is recycled and ready to fire.
- Memory Function: The flash can remember the current parameter after 3 seconds when the setting is finished. Operation data will be restored to the original data once restarted.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the strobe. For stubborn marks, a slightly damp cloth can be used, followed by immediate drying. Do not use harsh chemicals or abrasive cleaners.
- Flash Tube and Modeling Lamp: Handle these components with care. Avoid touching the glass directly to prevent oil residue, which can shorten their lifespan. Replace them if they become damaged or cease to function.
- Storage: Store the strobe in a cool, dry place, away from direct sunlight and excessive humidity. Always attach the lamp cover during storage and transport.
- Ventilation: Regularly check that the ventilation openings are clear of dust and debris.
