If an error occurs, the STANDBY LED will automatically
begin to flash. The number of times the LED flashes translates to a probable
source of the problem.
A definition of the STANDBY LED flash indicators is listed in the instruction manual for the user’s knowledge and reference. If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these problems occur.
