1. Summary of Self-Diagnosis Function
- This device includes a self-diagnosis function.
- In case of abnormalities, the POWER/STANDBY indicator automatically blinks. It is
possible to predict the abnormality location by the number of blinks. The Instruction
Manual describes blinking of the POWER/STANDBY indicator.
