• Select Audio Type. Select one of the three following audio types: All, Digital Only; and Analog Only. ALL: The radio will automatically detect the signal and receive it in the appropriate mode. Select ALL if you don't know what mode is being used for that frequency. IMPORTANT: In this mode for any signal, the radio outputs audio and stays on that frequency for as long as the received signal lasts. Even for a digital signal that cannot be demodulated or a control signal that does not contain sound, the radio recognizes it as analog signal so that, after receiving it, the radio stays on that channel until the signal disappears. If you know that digital communication is used on this signal, it is highly recommended that you set Audio Type to Digital Only. Digital Only: The radio will scan assuming only digital signals are coming. Digital communications that cannot be demodulated and data signals (such as control signals) are ignored; scanning resumes after data channel signals are received. Caution: It may appear that the Squelch setting is not effective in Digital Only mode as there is no apparent change when adjusting the Squelch level. However, during scanning, the Squelch setting value is indeed used to determine the presence or absence of a signal. If you start scanning with the squelch set to open, it would require checking each time as to whether or not there is a digital signal that can temporarily pause and demodulate even on channels without a signal. This would slow down the scanning process. Therefore, before starting scanning in Digital Only mode, always ensure that the squelch is not set to open. It is recommended to either set the squelch value to the level used when receiving analog signals or pre-set the squelch level to around 2 or 3 before starting the scan. Digital code search and filtering by Color Code, RAN code, and IDAS Area are possible. Analog Only: The radio will scan assuming only analog signals are coming. - Since the digital signal is not demodulated, it becomes data sound. - Squelch is enabled. Check the Squelch level. - CTCSS/DCS included in the received signal can be searched and filtered. 27

Select Audio Type
.
Select one of the three following audio types: All,
Digital Only;
and Analog Only.
ALL
: The radio will automatically detect the signal and receive it in the
appropriate mode. Select
ALL
if you don’t know what mode is being used
for that frequency.
IMPORTANT: In this mode for any signal, the radio outputs audio and
stays on that frequency for as long as the received signal lasts. Even for
a digital signal that cannot be demodulated or a control signal that does
not contain sound, the radio recognizes it as analog signal so that, after
receiving it, the radio stays on that channel until the signal disappears.
If you know that digital communication is used on this signal, it is highly
recommended that you set Audio Type to Digital Only.
Digital Only
: The radio will scan assuming only digital signals are coming.
Digital communications that cannot be demodulated and data signals
(such as control signals) are ignored; scanning resumes after data
channel signals are received.
Caution: It may appear that the Squelch setting is not effective in
Digital Only mode as there is no apparent change when adjusting the
Squelch level. However, during scanning, the Squelch setting value
is indeed used to determine the presence or absence of a signal.
If you start scanning with the squelch set to open, it would require
checking each time as to whether or not there is a digital signal that
can temporarily pause and demodulate even on channels without a
signal.
This would slow down the scanning process. Therefore, before
starting scanning in Digital Only mode, always ensure that the
squelch is not set to open.
It is recommended to either set the squelch value to the level used
when receiving analog signals or pre-set the squelch level to around
2 or 3 before starting the scan.
Digital code search and
fi
ltering by Color Code, RAN code, and IDAS
Area are possible.
Analog Only
: The radio will scan assuming only analog signals are
coming.
-
Since the digital signal is not demodulated, it becomes data
sound.
-
Squelch is enabled. Check the Squelch level.
-
CTCSS/DCS included in the received signal can be searched
and
fi
ltered.
