Troubleshooting and instructions

We have produced some instructions and troubleshooting pages for specific units. You can find them here.

Night vision setup guides

We have produced a video series showing how to use all of our night vision devices. You can find them all on our youtube channel or you can watch the instructions for the Nightfox Swift 1 here.

My Nightfox 100V won't turn on

If you’re having difficulties getting your Nightfox 100V to turn on. Please kindly check the following:

  • That all eight of your batteries are alive and kicking - just one dud battery will prevent the unit from working
  • That all eight batteries have the negative side pressing against the springs
  • That you’re holding the power button down for 2-3 seconds. Once the unit is on, the screen will illuminate

If you continue to have issues, get in touch with us and we’ll, of course, be happy to help out!

My device won't stay on, or turns off when IR is enabled

If you’re having difficulties turning up the IR on your nightfox, or doing so causes the unit to cut out, the problem commonly occurs when one of the batteries installed in the device is a dud. What happens is the remaining batteries can’t deal with the increasing strain (as you increase the IR strength) and the unit eventually cuts out. 

Please check the batteries you have installed and see if this fixes the problem - if you continue to have issues, get in touch with us and we’ll, of course, be happy to help out!

The image on my device isn't clear

All Nightfox binoculars have a manual focus. Please check the following,

•You are using the focus wheel, the position of the focus wheel varies on each device.
•On the Nightfox 100V, if the focus wheel is stuck you can twist the lens at the front to focus the image and this will also loosen the focus wheel.
•The IR is on, and set to maximum brightness.
•The lens cap has been removed.

Please contact us for more support.

My device works in the day, but not at Night

For devices such as the Corsac, 100V and 110R ensure that you have removed the lens cap from your device for use at night and that you have turned the IR setting up to the maximum level.
