6. Troubleshooting

If you encounter issues with your AULA 21 Key Tri-Mode Number Pad, refer to the following common problems and solutions:

• Connection Issues (Wireless/Bluetooth):
  If the number pad fails to connect or frequently disconnects, ensure it is fully charged. Re-pair Bluetooth devices or re-insert the 2.4GHz dongle. Ensure no strong interference sources are nearby. Try connecting via wired mode to confirm basic functionality.
• Number Pad Not Responding After Sleep:
  The number pad enters a sleep mode to conserve battery. To wake it up, press any key. If it takes multiple presses, ensure the battery is sufficiently charged.
• Keys Not Functioning Correctly:
  If specific keys are unresponsive or exhibit glitches, check if the switches are properly seated. For hot-swappable switches, try removing and re-inserting the affected switch. If the issue persists, consider replacing the switch. Ensure the number pad is in the correct operating mode (wired, 2.4GHz, or Bluetooth).
• Backlight Not Working or Incorrect:
  Check if the backlight is turned off by pressing FN + Num. Adjust brightness using FN + Up/Down Arrow. If issues persist, try resetting the number pad (if a reset function is available, consult the manufacturer's website for details).
• Poor Battery Life:
  Battery life can vary based on usage and backlight settings. Ensure the number pad is fully charged. Reduce backlight brightness or turn off the backlight when not needed to extend battery life.
