How do I know when the battery is low?

Why won't my 2.4GHz connection work?

Ensure you've selected "Connect" - "2.4G Mode" in the LCD menu before plugging in the receiver. If pairing fails, scroll to "2.4G Mode" and press and hold the knob for 5 seconds to enter pairing mode. Keep the receiver within 20cm of the keyboard during pairing.

Yes. Connect via Bluetooth and select the appropriate system in the LCD menu (iOS for iPads, Android for Android tablets). The keyboard supports all devices with external keyboard capability.

What's the difference between wired and 2.4GHz modes?

Wired provides unlimited power and zero battery concerns. 2.4GHz offers wireless freedom with gaming-grade latency (typically 1-3ms). Bluetooth adds multi-device switching but slightly higher latency (8-15ms).

Long nail compatibility?

Excellent for long nails. The centered typing position keeps hands naturally aligned, and the dedicated number pad means you're not reaching across smaller layouts. Consistent key spacing and standard finger positioning reduce strain on nail extensions. The gasket structure provides a soft, delicate feel that's comfortable for extended typing sessions.
