all signals on a given channel. This feature is useful when communicating
with other parties at extreme range.

in about 5 seconds, or when the monitor button is pressed momentarily
once again.
Push To Talk (PTT) Button (4, *3)
Pressing and holding this button will allow you to speak to any transceiver
that is set to the same channel and privacy code setting as yours. Hold the
transceiver approximately 1 to 2 inches from your face as you speak into
the built in microphone (12, *14). After you have finished speaking, release
the PTT Button to allow reception of incoming signals. It is not possible to
transmit and receive at the same time. The Transmit/Monitor LED at the
upper inside right corner of the LCD Panel (7, *6) will light red while the
PTT Button is pressed.
Releasing the button allows the unit to revert to standby mode. When
receiving an incoming signal, the Transmit/Monitor indicator will light green,
and the received signal strength indicator (
) will display the
relative strength of the signal.
The PTT Button can also be used as a two-way call ringer. Pressing the
button twice quickly will call another party on the same channel. The call
ring melody will sound on the receiving unit for approximately 3 seconds.
