switched to the following two alarm displays (alarm display modes). The alarm display mode can
be selected in the menu screen. For details on setting, see section 5-3. "ALARM/VIDEO LOSS".

sequentially for one second. Regular display operation is restored after all external alarms
and video loss signals are cleared.

detected. For details, see section 5-3. "ALARM/VIDEO LOSS”.

detected. For details, see section 5-3. "ALARM/VIDEO LOSS”.
If an alarm is input while displaying the menu screen, the alarm input is not detected. If
there is still an alarm input when returning to regular operation after exiting the menu
screen, the alarm input is detected.
