- Groups: Control up to 16 groups (0-9, A-F) of flashes.
- Channels: Select from 32 channels (1-32) to avoid interference.
- Remote Control: Use the X2T transmitter (or optional X1 TTL, XT16, FT-16 remote controls) to wirelessly trigger the flashes, adjust flash power levels, control the modeling lamp, and manage the beep function.
- Anti-Preflash Function: Enables synchronization with cameras that utilize a one-preflash firing system, ensuring accurate flash timing.

5.5 Triggering Methods
The flash units can be triggered using several methods:
- Sync Cord: Connect a sync cord from your camera to the flash unit's sync port.
- Test Button: Press the 'TEST' button on the flash head for a manual test flash.
- Slave Triggering: The flash can detect another flash firing and trigger itself (S1/S2 modes).
- Wireless Control Port: Use the X2T transmitter for wireless triggering and control.
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your lighting kit.
- Cleaning: Use a soft, dry cloth to clean the flash heads and accessories. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Do not use harsh chemicals or abrasive cleaners.
- Storage: Store the equipment in a cool, dry place, away from direct sunlight and excessive humidity. Use the provided lamp covers to protect the flash tubes and modeling lamps.
- Bulb Replacement: If a modeling lamp burns out, replace it with a new 150W modeling lamp of the correct voltage. Ensure the unit is unplugged and cooled down before attempting replacement.
- Fuse Replacement: If the unit fails to power on, check the fuse. Ensure the unit is unplugged before inspecting or replacing the 5A fuse.

9. User Tips
While specific user reviews or Q&A were not available, general tips for studio strobe users include:
- Test before shooting: Always perform a test flash and check your camera's histogram to ensure proper exposure before a full shoot.
- Softbox assembly: For easier softbox assembly, lay the softbox face down on a clean surface and insert the rods into the speedring first, then gently bend them into the corner pockets.
- Power management: Turn off the modeling lamp when not actively composing to extend its lifespan and prevent unnecessary heat buildup.
- Wireless range: While the 2.4G system offers good range, ensure line-of-sight between the transmitter and receivers for optimal performance, especially in environments with potential interference.
