NIX4 User's Guide

Thank you for purchasing a NIX Labs product. Our clocks are highly customisable while remaining easy to use right out of the box.

This documentation will help you get started and serves as your comprehensive guide to the advanced features, detailed product specifications, and device troubleshooting for your NIX Labs clock.

Important Precautions

Your clock is not a toy. Due to the nature of the display technology, it contains high voltage circuitry and uses glass tubes.

• Handle with Care: Always handle the clock gently to protect the glass tubes.
• High Voltage: Do not insert any objects into the gaps in the enclosure, as this presents a risk of electric shock from the high voltage components required to power the tubes.
• Keep Dry: Do not expose the clock to moisture or dew. Refer to operating and storage temperature limits in this manual. If condensation occurs, allow it to clear before powering on.
• Immediate Hazard: If a potential hazard arises (e.g. damage to the case or tubes that exposes circuitry), unplug the clock from power immediately and contact NIX Labs for support.

Nixie Tube technology

The NIX labs NIX4 clock features four genuine Soviet-made IN8-2 (ИН8-2) Nixie tubes.

Nixie technology provides a characteristic orange glow using wire-formed digits that are unlike any other modern display. This effect is achieved through gas ionization when a high voltage is applied to the tube's terminals, causing one of the internal cathodes (the specific wire shaped like a digit) to illuminate. More information about nixie tubes can be found on our website.

Model and Version Identification

The reverse side of each circuit board is marked with the product's model, major hardware revision (e.g. Rev A) and serial number (e.g. 18351).

The device's product and version information can also be found in the Web App by selecting the gear icon in the upper right and selecting Diagnostics from the menu.
