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 BC250D 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 BC250D 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
High 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.
