Motorola solutions ST7500 - DMO Private Priority Call; Talkgroup for Individual Calls; Communication through Repeaters

• GW + Rep – Uses the first available gateway or repeater for that talkgroup.
• Automatic – Uses the first available gateway for that talkgroup.
• Specific – Uses only the Gateway with the specified Gateway address for that talkgroup.
NOTE: When the Gateway and the Repeater cannot be communicated even though a
talkgroup to use them is configured, the radio attempts the direct MS-MS
communication.
Your service provider can disable any or all of these options.
When your radio detects the appropriate Gateway and/or the Repeater, the Gateway and/or Repeater
icons turns solid, respectively.
3.3.6
DMO Private Priority Call
The service provider may assign Pre-emptive Priority to outgoing DMO Private Calls. If this is the case,
DMO Private Calls from this radio preempt any ongoing calls (with the exception of emergency calls or
ongoing Pre-emptive Priority Private Calls) on the receiving radio, which then displays Call-
preempted.
3.3.7
Talkgroup for Individual Calls
Talkgroup for Individual Calls is a talkgroup that operates on a separate frequency allocated for
individual (private) calls only. Using this talkgroup optimizes frequency resources and helps not to
block other talkgroups. The only supported call types are: private calls and emergency calls (both
private and group). Use this talkgroup each time you need to make a private call.
When you select a Talkgroup for Individual Calls, your radio is not able to receive or initiate any group
or broadcast calls with priority lower than Emergency.
When you have selected a Talkgroup for Individual Calls and press the PTT button to start a Group
Call, the radio:
• Rejects the call
• Plays a tone
• Displays the Individual Calls Only message
3.3.8
Communication through Repeaters
Radios that are out of range and cannot communicate directly with each other in Direct Mode
Operation (DMO) can do it through the repeater. The repeater is a radio that repeats all communication
on a chosen channel, and as a result increases radios DMO range.
