PTT Express Voice Client
PTT Express Voice Client creates Push-To-Talk (PTT) communication capability between disparate enterprise
devices. Leveraging existing Wireless Local Area Network (WLAN) infrastructure, PTT Express delivers simple
PTT communication without the need of a voice communication server.
• Group Broadcast: Press and hold the PPT (Talk) button to start communicating with other voice client
users.
• Private Response: Press and hold the Left Scan/Action (Private) button to respond to the originator of
the last broadcast or to make a Private Response.
PTT Audible Indicators
The following tones provide helpful cues when using the voice client.
• Talk Tone: Double chirp. Plays when the Talk (or Private) button is depressed. This is a prompt for the
user to start talking.
• Access Tone: Single beep. Plays when another user just finished a broadcast or response. The user is
now able to initiate a Group Broadcast or Private Response.
• Busy Tone: Continuous tone. Plays when the Talk (or Private) button is depressed and another user is
already communicating on the same talkgroup.
• Network Tone:
• Three increasing beeps. Plays when PTT Express is acquiring the WLAN connection and ready for
voice communication.
• Three decreasing beeps. Plays when PTT Express has lost the WLAN connection and is not ready for
voice communication.
Enable PPT Communication
To enable the PTT communication:
1. Touch > PTT Express. The PTT Express window appears.
With PTT Express, when a user presses the Power button, the display turns off but the WLAN radio
remains on so that incoming calls can be received by the MC40.
