Maintenance
1. Cleaning the Keyboard

- Avoid using harsh chemicals or abrasive materials.
2. Battery Care
The integrated 6000 mAh Lithium Ion battery requires proper care:
- Avoid exposing the keyboard to extreme temperatures.
- Charge the battery regularly, even if not in frequent use, to prevent deep discharge.
- If storing the keyboard for an extended period, ensure the battery is charged to approximately 50%.
Troubleshooting
If you encounter issues with your IQUNIX ZX75 keyboard, refer to the following common solutions:
- Keyboard Not Responding:
Ensure the keyboard is charged. Check the connection mode switch (Wired, 2.4GHz, Bluetooth) and ensure it matches your intended connection. For wired connection, try a different USB port or cable. For wireless, re-pair the device or try a different USB port for the 2.4GHz receiver. - Bluetooth Connection Issues:
If experiencing interference, especially with other wireless devices like a trackpad, try switching to the 2.4GHz wireless mode or a wired connection. Ensure the keyboard is within range of your device. - Keys Not Registering or Missing Keycaps/Switches:
Verify that all keycaps and switches are properly seated. If a keycap or switch is missing or damaged upon arrival, contact customer support. The hot-swappable design allows for individual switch replacement if needed. - RGB Backlight Not Working:
Ensure the backlight is enabled via function keys or software. Check if the battery level is sufficient, as low battery can affect lighting performance. - System Mode Not Switching:
Ensure you are holding FN + TAB for the full 5 seconds to switch between Windows and Mac modes.
