This is useful when reprogramming the unit or making changes to
connected site equipment.
Sample Scenario
Maintenance needs to be performed on the transmitter. Naturally,
the best time for the transmitter to be down is around 2 a.m. Just
shutting down the transmitter will generate alarms, calling a
supervisor at 2 a.m. or calling the station engineer who is
performing the maintenance (and already knows the transmitter is
down). Thus, the station engineer could shut down the transmitter
for a one-hour period to perform the maintenance, and with the
alarms disabled, the system would not call the outbound
telephone numbers to report them. If maintenance is
finished prior to the one-hour period, the alarm reporting can be
enabled manually.
To enable alarm reporting before the end of the one-hour period,
enter:
 “0 3 0 #”
The VRC2500 will respond:
• A
LARM REPORTING ENABLED
QUERY CURRENT VRC UNIT
Occasionally, it may be necessary to query the VRC2500 to
determine its network address, the security level where the user
is logged on, etc. To do so, enter:
 “0 *”
The VRC2500 will respond with it’s network number and identify
the access level (observer or operator).
Remote/Local Status
To determine the state of the Remote/Local button on the
VRC2500 unit, enter:
 “0 9 0”
The VRC2500 will respond with the state of the Remote/Local
button (remote mode or local mode).

A for a complete list of the
DTMF codes to use when
accessing the Voice Interface in
Voice Mode.
