The TA-1/PT Telephone Set must be removed from its carrying case and connected to a field wire network to be operable. Connection is simplified through the use of dual binding posts. To transmit a call, a press-to-activate switch is repeatedly pressed to generate a signal of intent to communicate with a distant party. The distant party acknowledges verbally. To transmit a message, a press-to-talk switch is pressed. The telephone is then used as a conventional phone would be used with the exception of the need to release the press-to-talk switch to permit the incoming message to be heard. Communication continues through the alternate pressing and releasing of the press-to-talk switch to speak or listen. To receive a call, a preset buzzer will sound and/or a visual indicator will show white on black. This signal is acknowledged verbally after pressing the press-to-talk switch. Communication continues through the alternate pressing and releasing of the press-to-talk switch to speak or listen. When use is temporarily discontinued, the telephone set is placed in a ready condition by resetting the visual indicator and the buzzer volume. To disconnect for transport, the field wire is removed from the binding posts, the telephone set placed into its carrying case, and the case secured against the weather through the use of a zipper or latch.
