2:DELAY
You can set delay for a trunk system on a bank by bank basis. If you’ve set
delay for 1 second, then there will be a one second delay in Trunk Search
for that bank and a one second delay for all the talkgroups you have
programmed into Scan List memory. You cannot set delay individually by
talkgroup. The default delay is two seconds.
3:TONE DATA
You can set a CTCSS (analog) or DCS (digital) subaudible tone for a
frequency. To do so you must have the SQ Mode in the System Menu set to
Tone SQ. You can also program a subaudible tone easily by pressing the E
key in Scan Hold mode after programming a frequency. This will bring up
the Tone Data menu without having to navigate the Menu. 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 three
beeps 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
three beeps.
5:ATTENUATOR
The BC785D 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.
6:STEPS
Your BC785D is programmed with default step sizes for each frequency
range (see page 1). Steps are important if you are interested in using the
VFO to tune off from a frequency programmed into memory or if you wish to
program a frequency that the default step size will not accept.
For example, in VHF Hi-band mode, the default step size between 148 and
162 MHz is 5 KHz. However, the FCC has recently instituted 7.5 KHz
channel intervals. If you wish to enter 155.4075 into the scanner without
changing the default step, the scanner will change the programmed
frequency to 155.4100. Use the Menu to change the default step size to 7.5
KHz and then you will be able to enter 155.4075.
7:MODE
Default Auto receive modes are also programmed into memory. AM for
aircraft and CB bands, for example. All frequencies (other than audio TV
broadcast) above 400 MHz are received in NFM mode which helps prevent
adjacent channel interference. You can change the default settings on a
per-channel basis with this Menu item.
