3. Tone Search - In this mode, as soon as the scanner stops on any (non-trunked)
channel, the scanner will begin to search for any subaudible tone that is being
used on a transmitted frequency. The scanner will check each CTCSS tone
sequentially and it will find DCS tones instantly.
9:BANK TAG
Allows you to set an alphanumeric text tag for individual banks in the scanner
(1-10).(The "0" key represents Bank number 10.) For example, you may wish to set
the Bank One text tag as Law Enforcement, the second bank as Fire, etc.
2:CHANNEL DATA
Choose the channel number. The following options are available for the selected
channel only. Repeat using a different channel number, if necessary.
1:ALPHA TAG
Allows you to set an alphanumeric text tag for individual frequencies that you have
programmed. For example, you can set DAVIS PD CH #3.
2:DELAY
The default delay for all programmed channels and talkgroups is two seconds. At
the end of any transmission the scanner will remain on the frequency for two
seconds before resuming scanning. This will allow you to catch most replies. You
can change the delay to 1, or 4 seconds as well as set no delay (the scanner will
immediately resume scanning after the end of a transmission). With the BC780XLT
you can also set negative or inverse delays, also known as Pause. With a 5 second
pause, for example, the scanner will resume scanning after five seconds even if the
transmission you are currently listening to has not ended. Finally, you can set an
Infinite Delay. If a transmission is received on a frequency with Infinite delay set, the
scanner will stop on the channel and remain on it until you have hit scan,
search, etc.
3:TONE DATA
You can set a CTCSS (analog) or DCS (digital) sub-audible tone for a frequency. To
do so you must have the Squelch Mode in the System Menu set to Tone Squelch.
You can also program a subaudible tone easily by pressing the E(enter) key after
programming a frequency. This will bring up the Tone Data menu without your
having to navigate the Menu. You can also lock a tone assigned to a frequency. By
doing this you will receive all transmissions on the frequency, regardless of the
subaudible tone, except the one which you have locked. Any transmissions with that
tone will not be received.
4:BEEP ALERT
You can set a Beep Alert on a per-channel basis to alert you when specific
frequencies are active. For example, you may wish to be alerted anytime a mutual
aid fire frequency is active. With beep alert, you will hear a rapid three-beep tone at
the start of each transmission that you have flagged as such. You will also notice
that as you scroll pass the flagged channel(s), you will hear the tones.
5:ATTENUATOR
The BC780XLT comes with an RF Attenuation feature. If you are near an unusually
strong signal source, the signal may overload the scanner. The scanner may stop
repeatedly on that signal and miss other transmissions.
The RF Attenuation feature works in all modes and attenuates (reduces) the
incoming signal strength to prevent stronger signals from overloading the scanner.
