Receiving an Ambience Listening call
If an Individual call with an Ambience Listening command is
received from a specified station, the transceiver will auto-
matically transmit its microphone audio.
• The HM-148G or HM-152
HAND MICROPHONE
is required.
NOTE:
If the transceiver receives an Ambience Listening
command from a station other than the specified one, the
call will be ignored, and the transceiver will not transmit its
microphone audio.
D

q
When an Emergency call is received:
• Rings sound.
• “
Emergency
” and the channel number* are alternately displayed.

D
Talk back function
The Talk Back function allows you to select the same call
mode (Analog or Digital) as the received call.
If the received call is a digital signal, the Talk Back function is
activated for Voice and Emergency calls, and depending on
the pre-programmed settings, also for status messages and
SDM.
When the channel type is “Mixed-Digital”
After receiving an analog signal, “
ANALOG
” is displayed
during the Talk Back timer period, depending on the pre-pro-
grammed settings. When
[PTT]
is pushed before or during the
Talk Back timer period, you can transmit an analog signal.
When the channel type is “Mixed-Analog,” “Mixed-Digital”
or “Digital”
After receiving a digital signal, the calling station’s ID or the
Talkgroup ID is displayed until receiving a ‘Disconnect’ sig-
nal, depending on the pre-programmed settings. Even on a
“Mixed-Analog” channel, when
[PTT]
is pushed before re-
ceiving a ‘Disconnect’ signal, the Talk Back function allows
the transceiver to transmit a digital signal to the ID.
NOTE:
When this function is not activated, the transceiver
always transmits analog signals on “Mixed-Analog” chan-
nels, and digital signals on “Mixed-Digital” channels.
• On these channels, the transceiver can receive both analog and
digital signals, regardless of the Talk Back function.
