Optical triggering on the FJ400 and FJ200Updated a month ago

The FJ400 and FJ200 features an optical sensor that allows it to be triggered remotely by another flash or strobe unit fired nearby. 
On the FJ400 this sensor is located near the mini plug and air intake on the bottom of the unit. 
On the FJ200 it is located just above the LCD screen on the back face. 
It’s important to know the locations of these as optical sensors need line of site of the triggering flash. It is only available when units are set to Manual mode, as TTL and HSS data cannot be transmitted.

Enabling optical triggering with the FJ400 

1. Set to Manual Mode: Ensure the FJ400 is in Manual mode by going to Menu 1 and change the mode to Manual. (M)
2. Enable Optical Sensor: Enter Menu 3 and press the button next to the Eye icon to activate the optical sensor. The Eye icon will appear on the screen and CH and GR will disappear when optical triggering is enabled.

Enabling optical triggering with the FJ200

1. Enter Settings Menu: Press in on the control dial/select button.
2. Enable Optical Sensor: Navigate down until you see the “Optical” setting. Press in on the control dial to select it, rotate the dial to change “OFF” to “ON”. Press in on the control dial again to confirm your selection. 
3. Exit The Menu: Press the modeling lamp/return button to exit the menu.

With the optical sensor activated, units will fire simultaneously with an initial flash from any make or model, provided the flash output is sufficient and the sensor detect the signal.

Important Notes:

• FJ200 Resuming Normal Function:  When you revert the “Optical” setting to “OFF” you must also re-enable “TTL-ALL” in the “Wireless” setting to resume normal wireless flash functionality.
• Preventing Sleep Mode: 
  • FJ400: Enter Menu 6 by long-pressing the top menu button and set the Auto-off option to "OFF." 
  • FJ200: Enter the settings menu by pressing in on the control dial/select button and set the Auto-off option to "OFF."
  • If this option is not available, check your firmware version for updates, as early firmware versions may not include this setting.

The optical sensor is a useful alternative when an FJ trigger is not available or operational, but for optimal functionality.
