are set, press the push-to-talk (PTT) switch to transmit voice messages. Release the
PTT to receive voice.
Text Communications
Text communications take place in much the same way as text messages are
performed in common cell phones. Once the communications channel and transmit
mode (Broadcast, Group, or Private) are set, use the main menu to select Messages
and type the desired message.
Data Communications
Data communications include video and require connection to a computer using the
USB cable. The computer, in turn, is connected to the data source such as a video
camera. The Pathmaker is used to transmit the data to the next link.
Voice Communications
There are four levels of communications and they are called Talk Modes. Each Talk
Mode has a defined priority over the other modes. The Talk Modes are Broadcast,
Group, Private, and Priority. The terms refer to the transmit characteristics of a given
mode. A given talk mode defines which network members are targeted to receive a
message. It does not restrict reception from other radios.
For example, a radio in broadcast mode will be heard by any other radio that is using
the same channel and is also in receive mode (PTT not pressed).
A radio set to the group talk mode will only be heard by radios in the same group.
A radio in private talk mode will only be heard by the radio selected for private
communications. It is like a phone call.
In each of these cases, the transmitting radio will only be heard by radios that are in
receive mode (PTT not pressed) and on the same channel. Other radios that happen to
be transmitting at the time of the call are not affected until they are also in receive
mode.
Priority mode is a special case of broadcast. The transmitting “commander” radio not
only interrupts any currently received communication, it also disables the transmissions
of any radios that are transmitting and places them into receive mode as long as the
Commander’s PTT is depressed.
