6. Maintenance
6.1 Cleaning
- Use a soft, dry cloth to wipe the keyboard case.
- For keycaps, use the provided keycap puller to remove them and clean with a mild soap solution if necessary. Ensure they are completely dry before reattaching.
- Use compressed air to remove dust and debris from between the keys.
6.2 Switch Replacement
To replace switches, gently remove the keycap using the keycap puller. Then, use a switch puller (not included, but often comes with switch sets) to carefully extract the switch. Align the new switch's pins with the PCB sockets and press firmly until it clicks into place. Ensure pins are not bent during insertion.
6.3 Disassembly
For advanced maintenance or customization, the keyboard can be disassembled. Access the screws on the bottom of the keyboard by carefully removing the rubber strip. Use the included screwdriver for this process.
7. Troubleshooting
7.1 Connectivity Issues
- No Connection: Ensure the keyboard is charged and the mode switch (Wired/Wireless) is set correctly. For 2.4GHz, ensure the dongle is properly inserted. For Bluetooth, ensure the keyboard is in pairing mode and visible to your device.
- Lag/Delay: In 2.4GHz or wired mode, the polling rate is 1000Hz for minimal latency. Bluetooth mode has a 125Hz polling rate, which may introduce slight delays compared to wired/2.4GHz. Ensure no interference for wireless connections.
7.2 RGB Lighting Problems
- Lights Not Working: Check the keyboard's lighting settings via the NuPhyIO software. Ensure the keyboard is not in a low-power mode that disables lighting.
- Dim Lighting: Adjust brightness settings. Remember that PBT keycaps do not allow light to shine through the legends, so only the underglow and side lighting will be visible.
7.3 Key Functionality
- Incorrect Key Output: Verify the system compatibility switch (Win/Mac) is set to the correct operating system. Use the NuPhyIO software to check and reset key mappings if custom configurations are causing issues.
- Unresponsive Keys: If a specific key is not responding, it may indicate a faulty switch. Utilize the hot-swappable feature to replace the switch.
7.4 Battery Life
The Kick75 features a battery capacity of 2500mAh (NuPhyIO version) or 4000mAh (QMK/VIA version). Expected battery life is up to 360 hours with the backlight off and up to 90 hours with the backlight on. If battery life is significantly shorter, ensure the keyboard is fully charged and consider reducing RGB brightness or disabling it when not needed.
