1. Tric status LED doesn't light.
  • Use two new AAA batteries
  • Make sure the positive and negative ends are facing the correct direction
  • Turn the switch on
2. It didn't flash!
  • Make sure TricCam or TricCam Lite app is running, but not both
  • Make sure Tric is switched on and status LED is solid, not flashing
  • Make sure the flash unit is properly installed to the hotshoe in correct direction, or connected through a proper PC terminal cable
  • Make sure the flash unit is powered on, and not in sleep mode
  • Make sure the flash unit is in Manual Mode, not any TTL or optical client mode
  • If TricCam app’s sync button does not turn to green, restart Tric and/or TricCam app
3. Photo is only partially exposed by flash, or there is a dark line or area on photo

This means Tric and TricCam app are not synced. Try the followings:

  • Set Shutter Speed to 1/30 seconds if using paid TricCam app
  • Make sure Settings app -> TricCam/TricCam Lite -> Auto Exposure is OFF
  • Wait for 20 seconds and try again
  • Tap the sync button on TricCam app
  • Restart Tric and/or TricCam app
4. Photo is too bright or overexposed

This is mainly caused by camera sensor’s slow sync speed. Try the followings:

  • Set ISO to minimum
  • Set flash output power level to minimum
  • Use bounce flash, a diffuser, or ND filter
  • Move flash away from subject
