Motorola ST7000 Product Information Manual

2.10.3
Emergency Alarm
The emergency alarm is a special status message sent to the infrastructure while starting the
Emergency Operations. The radio may wait for infrastructure acknowledgment for this alarm and
attempts retries.
Each time the radio enters the Emergency Operation, it sends an emergency alarm. When an
emergency alarm is sent successfully, the respective audible tone sounds.
In addition, once the radio is in Emergency Operation and on pressing the programmed Emergency
button, an extra emergency alarm is sent. The only exception of this condition is during Hot
Microphone transmission.
The message can be dispatched both in Trunked Mode Operation (TMO) and Direct Mode Operation
(DMO).
2.10.4
Emergency SDS Status
Emergency Short Data Service (SDS) Status allows the radio to send a status message with a pre-
programmed value to the destination address set up in the codeplug.
This feature is available in Trunked Mode Operation (TMO) only. If no status acknowledgment or
negative acknowledgment is received, the radio retries sending the message. If Emergency Alarm or
Hot Microphone is configured, status is not sent.
2.10.5
Emergency Hot Microphone
The Hot Microphone allows you to talk without pressing the PTT button during Emergency Operation.
The transmission continues for a provisioned amount of time. Pressing the PTT button before the Hot
Microphone time expires ends the Hot Microphone operation. Then normal PTT operation in
Emergency group call takes over whereby the transmission is ongoing for the time the PTT button is
held.
Subsequent presses of the programmed Emergency button during the Emergency Operation restart
the Hot Microphone transmission.
If a talk permit is granted to another member of the group, the Emergency Call received tone is played.
If configured, the radio automatically attempts to get talk permit again.
Pressing the Back touch icon ends the Hot Microphone operation.
2.10.6

have the Hot Microphone switched on and off alternately.
If this feature is enabled, you can initiate the Alternating Hot Microphone by pressing the programmed
Emergency button.

• The radio exits the Emergency Mode.
