Self-Diagnosis By Remote Controller (Check Code) - Toshiba RAS-M10SMUV-E Service Manual

11-4. Self-Diagnosis by Remote Controller (Check Code)

1. The self-diagnosis by the check code is performed while items B to E blocks are displayed.
2. When turning the operation mode on the remote controller to the service mode, and operating the remote
controller, the controller of the indoor unit can self-diagnose operation of the protection circuit by displayed
contents (check code) on the remote controller, by whether all the lamps flash (5Hz) and the receiving
sound (Beep, Beep, Beep ... for 10 seconds) is heard. The timer lamp usually flashes (5Hz) during self-
diagnosis.
