Dear Nightfox Red Owner, 

Please follow the instructions below to update your Nightfox Red's firmware to our May23 version. You'll need a PC or Mac. 

The instructions below instruct you to download the firmware file, copy it to the Red's empty memory card, then turn the Red on in a special way. The firmware will then update itself in under a minute. 

The firmware will enable your Nightfox Red to use memory cards up to 512GB safely and reliably. If you were an early buyer of the Red, it may also give you a few extra picture adjustment settings. 

We hope the instructions are easy to follow and it should take under five minutes.

Please do let us know if you have any difficulties - we're here to help!

Before you start...

- Make sure your Red has some charge
- Have a memory card installed which is 32GB or less, for example the card that came with your Nightfox Red
- You'll need your Red's micro USB cable, or a USB card reader for the MicroSD memory card

1. Download and extract the .BIN firmware file

Download the firmware file by clicking here. 

The file is compressed, so you’ll need to “extract” it first.

Once extracted, you’ll be able to see the .BIN file:

Do not rename the file. 

2. Copy the file onto your Nightfox's memory card

Plug your Red into your Mac or PC using the USB cable (or use a memory card reader). 

The Nightfox's memory card will appear as a "USB Drive", similar to this:

Delete everything currently on the Red's memory card (including the folder "DCIM").

Then, copy and paste the “Rom_Code_NVH60X_V03.2.4_20230505.BIN” file onto the memory card:

Once the firmware is on the memory card, disconnect the Nightfox Red from its USB cable. 

If you used a memory card reader, slot the MicroSD memory card back into the Nightfox.

3. Upload the firmware onto your Nightfox

Before you carry out the below instructions, ensure your unit is turned off and that the memory card is inserted. 

Hold down the REC/MENU button. While doing so, hold down the POWER button:

Wait until it’s finished (it takes under 1min). When complete, the screen will flash and then power off.

4. Power on your Nightfox

Now power the unit back on the usual way by holding down the POWER button. Your Red will now be on the latest firmware version. 

Are these "IR", "Exposure" and "Backlight" options new to you?

In all firmware used since August 2022, the Nightfox Red night vision goggles no longer decide which Exposure Value is best for your current situation: You can pick how sensitive the Red is to light by adjusting the Exposure value. This gives you much better control over the quality of the picture.

To switch between adjusting IR, Exposure and Backlight, short press the POWER button. At the bottom of the display, the value being adjusted will show in red. Use the IR+ and IR- buttons to adjust the value up and down.

A high exposure value is best in dark conditions. It may allow you to use a lower level of IR, which will in turn save battery.

There are now 5 different levels for IR, Exposure and Backlight, rather than 7.

Let us know how you get on, and please do email help@nightfoxstore.com with any feedback you have!
