DMO Group Calls
Unless it is engaged in an active call, your MTH650 will
automatically switch to Group Mode and receive the transmission.
To answer the call, press and hold PTT.
Your MTH650 shows the Group name and the caller’s private
number or alias if previously stored in your address book.
For incoming call alert, see settings in the Vibrate menu option and the Tones

At the end of a call received through the earpiece, a low pitch tone is emitted
alerting you that the next incoming Group call will be received through the
speaker. At this alert, you are advised to hold the MTH650 at a comfortable
distance away from the speaker.
When receiving a Group call, you will hear a “New Group Call” tone.
The Broadcast Call (also called Site Wide Call) is a high-priority
group call from the console operator (or dispatcher) to all users. The
MTH650s are configured to monitor a Broadcast Call, but users
cannot talk back.
The Broadcast Call pre-empts an on-going Group Call that has the
same (or lower) call priority.
In DMO, the MTH650 can be used without your Service Provider’s
infrastructure.
Direct Mode allows communication with other terminals also
operating in Direct Mode, which are on the same frequency and
talkgroup as your MTH650.
In DMO it is only possible to place group calls and emergency group calls.
You can receive a call from the selected talkgroup and from an open
group. (An open group is a super-group of all DMO groups.)
When you start a call, the members of the selected talkgroup who
have their units turned on will receive the transmission.
In DMO the MTH650 can communicate with the trunking system
20
(and vice-versa) if the Gateway option is enabled in the MTH650.
Making a DMO Group Call
1. Enter Direct Mode by selecting the Direct Mode option via the
menu.
2. If this is the required talkgroup and range, press and hold the PTT
button. Wait for the talk permit tone and then speak into the
microphone.

DMO.
Your MTH650 will display the caller’s private number or alias, and
the talkgroup name.
Exiting DMO
To exit DMO, select the Operating Mode option your MTH650
should be operating on.

Phone and PABX Calls
The Phone Mode allows you to call a landline telephone number or
a cellular mobile phone number. In this publication we use “phone
number” when referring to these numbers.
The Private Automatic Branch Exchange (PABX) Mode allows
you to call local (office) extension numbers. This mode needs to be
activated by your Service Provider.
Both modes have the same dialling features.
While Transmit Inhibit is activated, an incoming Phone or PABX Call
is indicated, but it is not possible to answer the call.
Making a Phone or PABX Call
1. Press until Phone Mode appears on your display.
If a PABX call is required, press again. PABX Mode
appears on your display.
2. Proceed as for making and receiving Private phone calls.

Entering or Exiting Emergency Mode
Sending an Emergency Alarm (TMO Only)
You can send and receive Emergency Group Calls in Tru nke d
Mode (TMO) or in Direct Mode (DMO). If your terminal is
configured to operate through a gateway, Emergency calls can be
placed through the gateway.
You can initiate an Emergency Group Call to and receive it from the
selected talkgroup (TMO and DMO).
Your Service Provider will configure the Emergency Alarm and Hot
Microphone features.
Emergency calls will be allocated emergency priority in the system.
To enter Emergency mode from any mode, press and hold the
emergency button at the top of the MTH650.
The required time you need to press the Emergency button is set to default to
0.5 seconds. The time can be configured by your Service Provider.
For call alerts, see settings in the Vibrate menu option and the Tones menu
option.
To exit Emergency mode, press and hold Exit. You will switch to
normal Group mode.
Your MTH650 will automatically send an Emergency Alarm when in
Emergency mode. This is sent:
• automatically, upon entering Emergency mode
• if you press the Emergency key again while the MTH650 is in
Emergency mode.
After sending the alarm, the screen will show one of the following
delivery reports:
• Alarm Sent
• Alarm Failed
In both cases the screen returns within a few seconds to the main
screen of the Emergency mode.
24
.
The Emergency Alarm is a special status message sent to the dispatcher
monitoring the selected talkgroup. This can be used in dispatch systems to
highlight emergency calls.
Some systems do not support the Emergency Alarm feature when the user is
in a “Local Area Service” area.
Pressing the Emergency button, even if Transmit Inhibit is activated, causes
!!
the MTH650 to radiate immediately. The MTH650 must NOT be within the RF
Warning
sensitive area when entering Emergency mode.
Hot Microphone Feature
If the Hot Microphone feature was programmed into your MTH650
by your Service Provider, you can make an Emergency Group Call
and talk to the dispatcher (and members of your talkgroup) without
the need to press and hold the PTT.
The microphone will stay open for a time period (programmed by
your Service Provider). The microphone will stay open until:
• the Hot microphone time period expires
• you press PTT during the Hot Microphone period
• you press the End key
At the end of the Hot Microphone the Emgcy Mic Ended message
will be displayed and the MTH650 reverts back to the Emergency
Mode. The Hot Microphone feature is disabled and PTT operation
returns to normal.
If required you can resume Hot Microphone by pressing the
emergency key again.
