Receiving Signals; Transmitting - GME GA9800 Instruction Manual

Receiving signals

While the TX670 is not receiving signals, it will remain in the
Standby mode to conserve battery power.
When a signal is received, the LED indicator on the upper edge
of the radio will light green and the icon will appear on the
display. Adjust the Volume control for a comfortable
listening level.
If the incoming signal is encoded with a CTCSS tone that
matches the one set in your radio, the LED indicator will light
orange and you will be able to hear the signal in the speaker.
If the LED indicator lights green and the icon appears
but you cannot hear the signal, it is likely that your radio has
CTCSS enabled and the incoming signal is not using your
selected CTCSS tone (see 'Mode Settings' for more details on
CTCSS settings).
If no further signals are received, the unit will revert to
Standby mode.

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
