Introduction
Thank you for purchasing the Westcott FJ400 Strobe. The FJ400 and FJ-X2m Wireless Flash Trigger
(sold separately) are a photographer’s dream combination. The performance of the FJ400 is one of the
industry’s first compact, portable 400 watt-second strobes that are capable of recycling in less than
one-second at full-power so you don’t miss the shot. It offers the most full-power flashes at 480 bursts to
extend those on-location shoots when AC power isn’t an option and it has accurate color temperatures
throughout its entire 9-stop output range. When paired with the FJ-X2m Wireless Radio trigger, you can
say, “Goodbye,” to the need for multiple brand-specific triggers. The FJ400 and FJ-X2m have you
covered with its multi-brand compatibility. This versatile unit offers everything required by professional
photographers today to achieve lighting success - including TTL, HSS, Continuous Capture, Freeze
Function, and so much more. Enjoy!

Important things to know before starting…
Reviewing Firmware Files
Firmware updates will be made available on the FJ400 product page (https://www.westcott.com/4700)
to improve the performance of the FJ Wireless System. Please review ALL documentation that’s included
with each firmware download to ensure all of the necessary steps for preparation are complete before
installing the firmware.
TTL ±3 Flash Exposure Compensation (FJ400 & FJ-X2m)
±3 TTL Flash Exposure Compensation (FEC) on the FJ-X2m is independent of the Flash Exposure
Compensation (FEC) on the FJ400 Strobe. Meaning, a change of the FEC ±3 on the FJ-X2m will adjust
the light output in TTL mode, however, the FJ400 screen will not indicate the FEC changes made on the
FJ-X2m. The FJ400 FEC can be further adjusted ±3.
Set the strobe display to show both the FJ400 Strobe FEC (large letters) and the FJ-X2m Wireless Trigger
FEC (small letters) by turning the M->TTL setting to ON in MENU 6 on the FJ400. Learn more about
accessing the FJ400 Menu Settings in the section titled “Menu Screen #6“.
Canon Continuous Mode
When photographing in Canon Continuous Mode, two overlapping-squares will be visible on the FJ400
screen and the FJ Wireless System will default to Manual Mode disabling TTL and HSS functionality. Exit
Continuous Mode on the Canon camera to resume TTL and HSS functionality.

FJ400 Strobe: Warnings
Caution
●IMPORTANT: During operation, the flash tube, LED modeling lamp, and select components of the
FJ400 strobe temperatures will increase. Please use caution while using to avoid serious burns or
injuries.
●Use only with the Westcott FJ400 AC/DC Lithium Polymer Battery and/or AC Power Adapter and
Cord.
●Do not touch glass diffusion dome, flash tube, LED modeling lamp, or metal reflector after
immediate use to avoid potential injury.
●Never leave unattended around children and/or pets.
●Keep away from fire, water, and moisture.
●Do not submerge in water.
●Avoid drastic temperature changes before, during, or after use.
●Avoid direct skin contact with the flash tube and LED modeling lamp when replacing the flash
tube.
●Always remove the FJ400 AC/DC Lithium Polymer Battery from the FJ400 Strobe during
travel/storage to avoid accidental operation which could lead to overheating or permanent
damage.
●Do not overtighten the tilter bracket tension knob or umbrella tension screw.
●Ensure the FJ400 is securely mounted before use.
●Only use compatible modifiers and accessories and ensure they are securely attached to the
FJ400 Strobe before use.
●Do not attempt to modify any Westcott products. Contact Westcott for assistance.
●The operating temperature range is 32-104°F(0-40°C).
Dual-Stage Heat Protection
The FJ400 is equipped with self-monitoring cooling fans to ensure safe operation. It is also equipped
with an automatic shutoff feature. In the rare event that the strobe has reached an unsafe operating
temperature, the screen will display OH (overheat). Once the unit has cooled, the OH will disappear from
the screen and it will then be safe to continue operation.

FJ400 Strobe: Firmware Updates
The FJ400 strobe is designed with a USB-C port to allow for firmware updates only. Future firmware
updates will result in performance enhancements, modified menu options, and improved menu layouts. It
is strongly suggested that you visit westcott.com/4700 to confirm your strobe has the latest firmware.
Installing the Firmware
1. Visit westcott.com/4700 and scroll to the Support section. Find and download the latest
firmware ZIP file. (Note: Various browsers may automatically unzip the ZIP file. In this scenario,
skip to Step #3).
2. Unzip the file and open the extracted folder.
3. IMPORTANT: Read ALL FILES located in the extracted folder (i.e. README, Changelog, etc).
4. Ensure the FJ400 is OFF and cooled before removing the battery from the strobe.
5. Connect the USB-A to USB-C cable to the FJ400’s USB-C port.
6. Common operating systems will present the strobe as an external drive device.
a. NOTE: MacOS may display the external device on the desktop or in the Finder window.
7. Locate the .BIN file on your computer and drag the file to the FJ400 (external device).
8. Once the file has been completely copied to the FJ400, EJECT the FJ400 from the computer.
9. Remove the USB-C cable from the FJ400 and reattach the battery.
10. Press the Power | Model button on the FJ400 to initiate the firmware update and confirm
installation was successful by locating the firmware text in the bottom right corner of the screen
during the start-up process.
IMPORTANT
●If FJ devices don’t display as an external device after being connected to the computer, then
please disconnect the USB cable from both devices, restart the computer, and restart the
firmware installation process.
●It’s recommended that the firmware update installation process be completed only when the
connected computer’s power level is ≥ 50%. Loss of power of any type during this process could
render the FJ400 inoperable and require professional repair.
●Removing the USB-C cable from the FJ400 without properly ejecting the FJ400 from your
computer could render the strobe inoperable and require professional repair.
●Depending on the operating system and the applications running, copying the firmware from your
computer to the FJ400 may take a few minutes and/or halt the copying process. Should this
happen, close the copy progress window and try again. Further copying issues may require the
computer to be restarted.

FJ400 Strobe: Getting Started
Charging the FJ400 AC/DC Lithium Polymer Battery
The battery can be charged separately from the FJ400 or while attached to the FJ400. In both instances,
connect the power cord to the AC Adapter, connect the AC Adapter’s barrel plug to the battery AC
receptacle, and connect the power cord into a power outlet.
AC Adapter LED Indicator Light Colors
●Green: AC Adapter is plugged into a power outlet without a battery attached or connected to a
fully-charged battery.
●Red: AC Adapter is plugged into a power outlet and the battery is currently charging and less
than 100% charged.
Attaching the FJ400 AC/DC Lithium Polymer Battery
Attach the FJ400 Battery to the strobe by aligning the silver connection points on the rear of the strobe
to the holes on the silver strips located on the back of the battery and slide the battery down until it locks
into place.
Removing the FJ400 AC/DC Lithium Polymer Battery
Ensure the FJ400 is OFF by long-pressing the Power | Model button until the LCD screen turns off. Then,
slide the release lock located on top of the battery away from the strobe, gently press the battery up and
away from the strobe to remove.
AC Power Operation
1. Ensure the battery charge level is ≥ 25%.
2. Ensure the battery is securely attached to the FJ400.
3. Plug the power cord into the AC Adapter.
4. With the strobe powered off, connect the AC Adapter’s barrel plug to the battery’s AC receptacle.
5. Plug the power cord into a dedicated power outlet.
6. Turn the strobe ON by pressing and holding the Power | Model button until the start-up screen
appears.
