Disaster Alert; Table 11: Emergency Operation Dependencies - Motorola MTP3250 Funktionsbenutzerhandbuch

To receive the emergency alert, the radio must be in DMO or TMO, within RF range of the initiating
radio, and must not be in a call. When the radio receives the emergency alert, it joins the call
automatically.
The following table illustrates the dependencies between the current radio mode and the type of
emergency operation:

Disaster Alert

Disaster Alert call is a broadcast emergency call initiated by the radio, with emergency pre-emptive
priority that everyone in a broadcast area can hear. This feature is designed for catastrophic situations,
such as earthquakes, and has the highest priority over other calls. All radios under Disaster Alert
display emergency notification on their screens. The alert message, its duration, and destination
talkgroup can be configured in the codeplug.
To initiate Disaster Alert, switch the radio to Disaster Alert mode and press PTT button. When the call
ends, the radio exits the Disaster Alert state.
During Disaster Alert, other functionality is impacted:
• When Disaster Alert begins, any other ongoing services are terminated.
• No other services can interrupt this type of call.
• Hot Mic functionality cannot be used.
• Speech can only be in Clear mode, even if any of the encryption services are enabled. The only
exception is E2E Encryption.
NOTICE: Not all infrastructures support this feature. Consult service provider before enabling
this feature.
