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.

The PTT mode controls the keypad during a push-to-talk call period. 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 Initiate a call. Talk into the microphone while holding the Wireless Telephone two inches from your mouth.

Step 2 Release the Talk button when finished talking. The “end transmit” sound plays.

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. The display screen shows the current active channel. 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 phone ignores the Talk key while in the receive state. The screen shows the current active channel, the caller ID information of the
