My F121 will not connect to the trigger?

Please ensure you are on the correct channel on both the F121 and the F121 trigger. For example, channel 1 on the F121 and channel 1 on the F121 trigger. 

How do I change the flash tube to my [HB320/HBU250/INTS1/INTS1A/F121]?

Please see this video on how to change the flash tube.

Can another light fire my [HB320/HBU250/INTS1/INTS1A/F121]?

Yes! All our Interfit flash range will have optical sync which will enable your flash to be triggered by another light source, simply set the mode to CELL and your [HB320/HBU250/INTS1/INTS1A] will be fired by another light. Cell mode works on the speed of light, for best results use a direct line. Please note, on this mode you cannot control HSS or TTL.

How do I connect my [HB320/HBU250/INTS1/INTS1A/F121] direct to my camera with a sync lead?

With the sync cable that comes with the [HB320/HBU250/INTS1/INTS1A] plug it directly into the PC Sync Socket on your camera. Entry-level cameras do not have these, but you can buy an adapter. Like cell mode, you will not be able to control HSS or TTL using this method to fire the lights.

My trigger will not fire my [HB320/HBU250/INTS1/INTS1A/F121] when connected to my camera?

Check that the hotshoe settings on your camera are set up correctly, refer to your camera’s user manual. 

Please also make sure all contact points on both the camera and trigger are clean and are not damaged.

Can I use another trigger to fire my [HB320/HBU250/INTS1/INTS1A] other than the S1 Nikon, Canon Sony and Manual triggers?

We cannot guarantee any third-party equipment will work with our Interfit lights as they would not have been tested. If they do work, it is not guaranteed that you will be able to control HSS and TTL functions with them. 

Can I plug my [HB320 /INTS1/INTS1A/Monolight/F121] into an extension lead?

Yes, but like with any socket do not overload the extension lead and make sure it is a properly rated, surge protected extension lead.

Can I use my [HB320/HBU250/INTS1/INTS1A/Monolight/F121] in Europe?

Yes you can use your [HB320/HBU250/INTS1/INTS1A/Monolight/F121] in Europe.

There is a delay when firing my [HB320/HBU250/INTS1/INTS1A] or it fires intermittently?

Please ensure that both the light and the trigger are up to date with your camera model. You can find firmware here. You could be over firing the flash, the higher the setting of the light intensity, the longer the flash tube will take to recharge.

There is a delay when firing my F121 or it fires intermittently?

You could be over firing the flash, the higher the setting of the light intensity, the longer the flash tube will take to recharge.

The flash on my F121 does not work?
