1. LAN Indicator [LAN] (Green)
Lights when the LAN connection terminal (31) on
the rear panel is connected, and flashes during
LAN communications.
2. SX Link A Indicator [SX LINK A] (Green)
Lights when the SX Link A terminal (29) on
the rear panel is connected, and flashes while

4. Emergency Indicator [EMERGENCY] (Red)
Lights while the general urgency all-call is being
made (
) or when the SX-2000 system is in
an emergency condition, and flashes when a 24 V
emergency cutoff* state occurs involving any SX-
2000AO within the system.
* In the SX-2000 system, a 24 V emergency cutoff
input terminal that allows control of an emergency
audio input is provided on the SX-2000AO's rear
panel. When the SX-2000 system is combined
with another emergency broadcast system, a
24 V DC is normally kept being supplied to this
emergency cutoff input terminal and is cut off
(24 V emergency cutoff function) in emergency
situations. This interrupts the general-purpose
broadcast from the SX-2000, allowing the
emergency broadcast system to override it. (For
details, see
.)

Lights while the general urgency all-call (CPU OFF
state) is being made (
6. Standby Indicator [STANDBY] (Green)
