Turning Battery Save On/Off
The battery save features extends battery life by setting the
scanner in a low-power mode when it is held on a single
channel or frequency (in the search mode) and there is no
transmission.
3:SYSTEM OPTION → :BATTERY SAVE
1:ON
The battery save feature is on. You might miss a brief
portion of transmissions when held on a channel or
frequency, but battery life is extended.
2:OFF
The battery save feature is off.
Muting All Audio
To mute all audio, press and hold MUTE for 2 seconds. The
scanner operates normally, but no audio sounds from the
scanner. To turn audio back on, press and hold MUTE for 2
seconds.
Setting Squelch Mode
You can set the scanner to either stop on any transmission
during searching or scanning, or only stop on transmissions
that include a specific CTCSS or DCS subaudible tone (see
"Understanding Scanning" for information about subaudible
tones).
3:SYSTEM OPTION → 8:SQ MODE
1:CSQ
Carrier Squelch mode; the scanner stops on any
transmission regardless of whether a subaudible tone
is present.
2:TONE SQ
The scanner stops on transmissions that include a
matching subaudible tone or have no tone at all.
When you select this option, you also need to set the
appropriate tone in either the channel memory or for
the search range.
3:TONE SEARCH
When the scanner stops on a transmission, it will
then scan the subaudible tones to determine the
correct setting. When the scanner has found the
correct tone, it flashes the tone on the display. If you
store that frequency into a channel, the tone is also
stored.
