1. If the beeper does not sound again after the initial 2 beeps to confirm the self-check start signal was received and
the OPERATION INDICATOR lamp does not come on, there are no error records.
2. If the beeper sounds 3 times continuously “beep, beep, beep (0.4 + 0.4 + 0.4 seconds)” after the initial 2 beeps to confirm
the self-check start signal was received, the specified refrigerant address is incorrect.
