Troubleshooting and Maintenance
Troubleshooting Common Issues
- No Triggering/Shooting: Check battery installation, power status, channel/group settings, hot shoe connection, and mode settings.

- Interference: If experiencing interference, change the trigger's channel. Consider moving away from other 2.4G devices or changing their channels.
- Flash Recycle Time: Ensure the flash is fully recycled. Lower flash output if overheating. Switch to M mode if TTL issues persist.
- Distance Issues: Ensure the trigger and flash are within the effective range. Consider using a closer distance or setting the trigger's DIST to 0-30m.
- Low Battery: Replace batteries in both the trigger and flash.
Maintenance
- Prevent Drops: Avoid strong shocks or vibrations.
- Keep Dry: The product is not waterproof. Avoid moisture and high humidity to prevent internal damage.
- Temperature Changes: Protect from rapid temperature changes to prevent condensation.
