Check the exact model name and layout printed on the keyboard or packaging. Sections 01–09 apply only to Air75 V2 and Air96 V2; use the matching model card for every other model. Should I use VIA or NuPhyIO? Use VIA for Air60 V2, Air75 V2 and Air96 V2. Use NuPhyIO for Air60 HE, Air75 V3, Node75 and Node100. How do I pair Bluetooth or 2.4G? Follow the matching model instructions, then hold its model-specific channel key until the relevant indicator flashes quickly. The channel keys differ by model. What should I do if a wireless connection is unstable? Remove the old Bluetooth record and pair again. Keep the 2.4G receiver away from metal hubs, USB 3.0 devices and other transmitters. What should I know about Air75 V3 battery life and charging? Laboratory data rates the 4000mAh battery at 60–100 hours with all lights on and up to 1200 hours with RGB off. The official manual recommends a 5V/1A charger; turn lighting off for longer wireless use. How can I update firmware safely? Open the official firmware page and follow its latest instructions for selecting the exact model and layout. Which ANSI, ISO, JIS, Node75 or Node100 manual should I use? Confirm LP or HP first, then choose the manual matching the ANSI, ISO or JIS layout.
