3. Press and hold the Diagnosis (5 s) button for 5 seconds or longer while holding the smartphone mouthpiece to the logo until the data transfer is complete.
   • Keep the smartphone in place until the data transfer has finished. The time remaining for data transfer is displayed.

4. After the data transfer is complete, the diagnosis will be displayed in the application.

NOTE

• For best results, do not move the phone while the tones are being transmitted.
• Be sure to keep ambient noise to a minimum or the phone may not correctly receive the buzzer beeps from the indoor unit.
