REFERENCE Using Push to Talk (PTT) The push-to-talk feature allows MH120 Wireless Telephones to operate in a push-to-talk (PTT) group broadcast mode in addition to the standard telephone operation. The MH120 Wireless Telephone supports 8 multicast channels with the current channel saved in memory on the phone. A PTT call is initiated by pressing the Talk button located on the right side of the handset. All MH120 Wireless PTT dialogue is interrupted when you answer a PBX call. When the PBX call is ended, PTT dialogue resumes if it is an active call. The different push-to-talk features and terminology are discussed in the following sections. Selecting a Channel See "Setting User Preferences" on page 2-10. Mobile Handset 120 and Desktop Charger/Gang Charger User Guide - Revision 1 MH120 Wireless Telephone 2-7 The Call Period The two-way radio operates on the concept of a push-to-talk session or call period. The push-to-talk call period begins with the first transmission and ends when there has been no two-way radio traffic on the channel for 10 seconds. Therefore, it is not possible to use the keypad for any other function, such as accessing the on-hook menus or accessing an OAI application. However, it is possible to place a PBX call (see below). Initiating Calls Press the Talk button and wait two seconds to activate the channel before talking. The "start transmit" sound will play when you may begin talking. Transmitting Calls Use the following steps to transmit calls. Step 1 Step 2 Initiate a call. Talk into the microphone while holding the Wireless Telephone two inches from your mouth. The MH120 Wireless Telephone then enters the waiting state where it monitors the channel for up to 10 seconds. Step 3 (Optional) To initiate subsequent transmissions on the MH120 Wireless Telephone, press the Talk button, using the same channel. The "start transmit" sound plays immediately and the user can start talking. Since all phones on that channel are already in the receive state, there is no two-second delay. If no transmission occurs during the 10-second countdown period, the MH120 Wireless Telephone plays the "end call" sound and reverts to the idle state. If you inadvertently press any other button or key on the Wireless Telephone while transmitting a call, the call will be terminated. CAUTION Receiving Calls When a PTT transmission is received the phone plays the "receiving alert" sound and enters the receive state. In this state the phone receives all conversations on the selected channel. The screen shows the current active channel, the caller ID information of the Mobile Handset 120 and Desktop Charger/Gang Charger User Guide - Revision 1 2-8 MH120 Wireless Telephone current transmitter, and an indication that the phone is receiving a broadcast transmission. The caller ID is protocol specific. Usually it is the extension number programmed in the phone from the on-hook user menu. NOTE At the end of a transmission, the phone enters the waiting state where it monitors the channel for up to 10 seconds and displays "Waiting" on the screen.
