• How do I turn on my HAKINAKU carbon monoxide detector?

  For most portable models like the D6 or HD09, long press the power button to turn the device on. It will typically undergo a warm-up countdown (approx. 35 seconds) to calibrate sensors before monitoring begins.

• How do I connect my HAKINAKU radon detector to Wi-Fi?

  Ensure your phone is connected to a 2.4GHz Wi-Fi network. Download the Tuya Smart or Smart Life App. On the device (e.g., PT07), quick press the power button 3 times to activate the Wi-Fi icon, then follow the 'Add Device' steps in the app.

• What does it mean if the screen displays 'ERR'?

  If the screen displays 'ERR' and the alarm sounds repeatedly (e.g., 10 times every 30 seconds), it indicates that the gas sensor has failed or the device is broken. Discontinue use and contact support or replace the unit.

• How do I silence the alarm on HAKINAKU detectors?

  When an alarm sounds, you can usually press the 'S' button (or the designated function button) to temporarily silence the alarm. However, if dangerous levels of gas persist, the alarm may resume after a short timeout.
