trAnsmitting
To transmit, press and hold the Push-To-Talk (PTT)
switch. the other radio you are talking to must be set to
the same channel (and ctcss code if applicable). Hold
the tX670 approximately 5 to 8 cms from your face
with the antenna vertical and speak into the built-in
microphone.
While the PTT switch is pressed, the LED indicator on
the upper edge of the radio will light red and the
icon will appear on the lcD.
When you have finished speaking, release the PTT
switch to receive incoming signals (it is not possible
to transmit and receive at the same time). if no further
signals are received, the unit will revert to Standby mode.
TIP: the PTT switch can also be used to transmit a call
Alarm melody. When the call Alarm melody is enabled (see
Mode settings for more details on the Call Alarm settings),
pressing the
PTT switch twice quickly will call another
party on the same channel and play the call Alarm melody
in their radio’s speaker. When this happens, the
icon
will appear and the lED indicator will light red for about 3
seconds. the call alarm can only be sent once per minute.
