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.
Trunk Scanning Options
When you are scanning a trunked system, there are several trunking-only options available
to you. This section outlines these options.
Searching for Active Talkgroups (ID Search)
If you want to hear all activity on a system, use the ID Search mode. While scanning a
trunking system, press
SRCH while scanning that system; or, press and hold TRUNK until
the scanner flashes
READY TO ID SEARCH
. The BC796D stops on every active
talkgroup, regardless of whether you have programmed it into your scanner.
Notes: • If you have not yet programmed any ID’s for the system, this is the only mode
available.
