1. LED lighting
The [STATUS], [INPUT] or [SYNC] indicator on the front panel
lights orange (warning) or red (error), depending on the type of
error.
2. Display indication
The first line of the display shows a description of the error. When
the menu is displayed, errors are not shown.
Memoranda:
● With LOCAL, the error indication is shown when the error is
detected and goes out when the error is no longer detected.
With REMOTE, once an error is detected, the indication
remains (goes out when the switch is set to LOCAL).
● Error codes with 2 to 6 digits may be shown at the same time.
In this case, report the error codes to your JVC dealer.
3. [Alarm] connector output
2-line alarm output terminals are provided for the rear panel's
[ALARM] connector. Terminals A and B are short-circuited (relay
contact) when an error occurs or the power is turned off. Normally,
these terminals are open. (For open and short-circuited conditions,
refer to the table on the next page.)
The maximum rated value is 30 V 0.5 A for AC/DC with non-
inductive load.
