In TTL mode, the flash automatically adjusts its output based on ambient light conditions and camera metering. This provides precise automatic flashes for balanced exposure.
- Press the Mode button until "TTL" appears on the LCD.
- The flash will communicate with your camera to determine the appropriate power output.
- Flash exposure compensation can be adjusted via the flash unit or camera settings.

Manual mode allows you to set the flash power output manually, from 1/256 to 1/1, in 0.1 EV increments. This mode offers full creative control over lighting.
- Press the Mode button until "M" appears on the LCD.
- Use the control dial or buttons to adjust the flash power output.
- Supports S1/S2 optical slave control for off-camera triggering.
6.3. RPT Mode (Repetitive/Stroboscopic)
RPT mode fires a series of rapid flashes during a single exposure, allowing you to capture multiple movements of a subject in one picture.
- Press the Mode button until "RPT" appears on the LCD.
- Set the flash frequency (Hz), number of flashes, and power output.
- Experiment with settings to achieve desired stroboscopic effects.
6.4. 2.4G Wireless Q System
