Frequently Asked Questions - SK400II GODOX

How do I set the modeling lamp mode?

Short press the MOD/OFF button to cycle through modes: OFF, PROP (modeling lamp brightness follows flash power), and Percentage (manual 5%-100%). When in Percentage mode, press SET and turn the Select Dial to adjust brightness. Long press the MOD/OFF button to toggle the function that turns off the modeling lamp during flash.

How to use the built-in wireless control?

The flash has built-in 2.4G wireless. To turn it on, simultaneously press GR/CH and S1/S2 buttons. Use GR/CH to set group (0-F) and channel (1-32). Compatible with Godox triggers like X1 or XT16. You can also use the Wireless Control Port with the optional FT-16 remote set.

What is the difference between S1 and S2 slave modes?

S1 mode fires the flash synchronously with the first flash it detects (like a standard optical slave). S2 mode ignores the first pre-flash from cameras and fires only on the second, main flash, useful when using TTL pre-flash systems. Press the S1/S2 button to toggle.

How to replace the flash tube?

Turn off and unplug the flash. Wear insulated gloves. Loosen the iron wire on the tube, hold the two feet of the tube, and pull out gently. Remove the feet casing from the old tube and attach to the new one. Align the new tube's feet with the copper outlets, push in slightly, and twist the iron wire to secure.

What is the recycle time?

The recycle time ranges from 0.1 to 1 second, depending on the power output setting. At full power, it recycles in about 1 second.

What safety precautions should I take?

Do not disassemble; keep dry; use in a ventilated area; avoid flammable materials; wear insulated gloves when handling hot parts; do not flash directly into eyes; disconnect when not in use; replace fuse only with F8AL 250V type; after 30 continuous full-power flashes, cool down for 3 minutes.

How do I clean the flash?

Disconnect the power before cleaning. Use a soft, dry cloth to dust the exterior. Avoid sudden impacts. Regularly dedust the lamp to maintain performance. Do not use liquids or immerse in water.

What accessories can I use with this flash?

The flash uses a Bowens mount for accessories like softboxes, umbrellas, barn doors, snoots, and light stands. Optional Godox triggers (X1, XT16, FT-16) enable wireless control. Standard accessories included: power cord, lamp cover, modeling lamp.

What does the error code E1 mean?

Error code E1 indicates that the capacitance voltage is not rising within 1 second during charging. This may signal a problem with the power supply or internal circuit. Press the SET button to stop the alarm. If persistent, contact service.

What is the warranty period?

The product comes with a one-year warranty against defects, excluding consumables like the flash tube and modeling lamp. Unauthorized service will void the warranty.

▲ Please turn off the power and wear insulated gloves before installing and connecting accessories. When replacing the tube or modeling lamp, please make sure that the tube is cool and wear insulated gloves to prevent burns.
Do not flash directly towards naked eyes (especially those of babies), otherwise it may lead to visual impairment.
▲ Disconnect from the power supply when it will not be used for an extended period.
For continued protection against risk of fire replace only with same Type F8AL 250V fuse.
An apparatus with CLASS I construction shall be connected to a MAINS socket outlet with a protective earthing connection.
The MAINS plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.
After 30 continuous flashes at full power, the flash should be cooled down for about 3 minutes. Overheating will occur if it is used continuously without cooling down.
Do not keep using the modeling lamp for a long time; otherwise flammable accessories attaching to flash head, e.g. softbox will get burnt. A 10-minute time is recommended in this case. After 10 minutes, cool it down for 1 minute.
When using a snoot, do not keep the modeling lamp on for a long time or fire too frequently (not over six times for one minute). Overheating will result in damages for strobe housing and/or studio light.
- Avoid sudden impacts as this can damage the flash tube and/or modeling lamp. - The apparatus shall not be exposed to tripping or splashing and that no objects filled with liquids, such as vases, shall be placed on the apparatus.
Do not touch the area around this symbol since it is hot.
