5.1
Ambience Listening (AL) Call
Ambience Listening Call allows a dispatcher to make a special call that allows listening to the
conversations and background noises within the range of the microphone of a particular radio. The call
is set up without any indication to the affected radio, and any lower priority ongoing voice call or packet
data transfer may be preempted.
The call is set up without any indication to the affected radio, and any
lower priority ongoing voice call may be preempted.
After accepting the call, the radio transmits in a simplex call without any action from or indication to the
user. The Ambience Listening Call automatically ends when you initiate any voice call, switch to
Emergency or TXI Mode, or send Emergency Alarm.
5.2
Buffer Full Overwrite Policy
Upon receiving a text message, the radio places the text into a circular buffer. You are notified when a
new text message is received and a quick access to read the message is provided. If a delivery report
is requested, the radio sends it upon receipt of the message by SDSTL. If a consumed report is
requested, the radio sends it when you read the message.
NOTICE: If you read the message when the radio is out of service, the report may not be sent.
You can save incoming or edited (outgoing) text messages. These messages can be edited and sent.
You can also protect the message from being deleted or from the overwriting policy of the radio.
For each message, you can verify its timestamp. The timestamp displayed is extracted from the SDS
TL PDU. The timestamp is generated and inserted to the message by the SwMI.
5.3
Call-Out
NOTICE: This feature is a selling feature.
This feature allows you to receive Call-Out alerts. On receiving the Call-Out messages, the radio
interrupts current services and attends to the Call-Out alert without any further delay. After the Call-Out
is cleared by the dispatcher, the radio exits Call-Out mode and reverts to normal mode.
During Call-Out mode, you are only able to receive Emergency calls. However, if your service provider
configures Emergency Calls to be ignored during Call-Out mode, the radio rejects them with no
notification.
If your service provider temporarily blocked the use of PTT in the Call-Out, pressing PTT in the Call-
Out mode is considered an invalid key press until the timer expires.
The time-stamp on the Call-Out alert indicates the time and date when the Call-Out is received.
To read an entire Call-Out message, scroll down the screen by pressing the Down Navigation key. The
length of the message is indicated by the vertical bar on the left of the screen.
