6. Operating Instructions
6.1 Touchscreen Interface
The TR-Q8 features a full-color touchscreen for intuitive control. Tap on elements to select, and use the control dial or swipe gestures (if supported) to adjust values.
6.2 Channel and Group Settings
To avoid interference and control multiple flashes, set the channel (CH) and group (GR) settings. Tap on the CH or GR display on the screen and use the control dial to select the desired value. Ensure your flashes are set to the same channel and group as the trigger.
6.3 TTL Automatic Shooting Mode
In TTL mode, the TR-Q8 automatically adjusts flash output for accurate exposure based on your camera's metering. This mode is ideal for fast-paced shooting where lighting conditions change frequently.

6.4 Manual Mode
Manual mode allows you to precisely control the flash power output. Tap on the power level displayed on the screen and use the control dial to increase or decrease the flash intensity. This mode is suitable for consistent lighting setups.
6.5 High-Speed Sync (HSS)
HSS enables you to use flash at shutter speeds faster than your camera's native sync speed, allowing for wider apertures in bright conditions or freezing fast motion. Activate HSS through the touchscreen interface if your camera and flash support it.
6.6 TCM Conversion Function
The TCM (TTL Convert Manual) function allows you to quickly convert a TTL exposure setting into a manual power setting. This is useful for establishing a baseline exposure with TTL and then fine-tuning it manually for consistency.
