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.
