Understanding the Menu System
It is very important for you to understand the Menu screen. To navigate through the Menu
screen is really quite simple. Many of the features of this scanner, can only be accessed by
the menu screens. There are several ways to get through the screens. First of all, press
MENUto get started. Any time you want to exit this mode or simply quit from where you are,
repeatedly press 
MENUuntil the scanner returns to the original state. Anytime you are in the
Menu Mode, the audio...

Menu Description and Numeric Keypad Equivalents
Below are the menu screens and a brief description or purpose of the feature.
1:SYSTEM DATA
1:DIMMER 
Allows you to change the brightness of the display.
2:SCREEN MASK Screen Mask allows you to limit what appears on the display to the alpha tags that
you have set for a channel along with a few function icons. Screen Mask removes
the frequency, receiving mode, tone data, signal strength bars, and the trunking
repeater activity indicators. This mode is...

15 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.
10:BANK TAGAllows 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...

6:STEPSYour BC780XLT is programmed with default step sizes for each frequency range
(see inside front cover). Steps are important if you are interested in using the VFO
to tune off-frequency 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...

4:L/O ID REVIEWUse this menu item to review the IDs that you have locked out during Search and
Scan. Use the Up/Down arrow keys or turn the VFOto the left or right to view the
IDs that have been locked out. To leave the lockout IDs unchanged, press 
MENUto
back out of the menu. To unlock an ID, press the 
L/Okey. To unlock all the IDs that
have been locked out, press the 
E(Enter) key.
5:PROGRAM IDYou can program IDs into Scan List memory either during Trunk Scan or Search
without going into the Menu....

8:STATUS BIT (MOTOROLA)On Type II trunking systems there is a method by which specialized types of
communications utilize unique talkgroup numbers. An emergency call will occur on
a unique talkgroup from its primary assignment, for example. Because the
BC780XLT defaults to Status-Bit On mode, you never need to worry about missing
these transmissions. If youve programmed talkgroup 33264 into Scan List memory,
for example, and there is an emergency call within the group, you will hear it on
33264....

2:DELAYSet a delay for the search ranges. This applies to all ranges (See CHANNEL DATA-
STEPS for details).
3:ATTENUATORSet attenuation for all search ranges. (See CHANNEL DATA-ATTENUATOR 
for details).
4:TONE DATAThe default mode is off. This means that you will receive all transmissions on any
frequencies that are active within your search range(s). By selecting CTCSS or
DCS you can set the radio to receive only a particular subaudible tone to be
received during your search. You can also lockout a...

20 Before the BC780XLT can begin conventional scanning, you must program a frequency into
at least one channel. Repeat this procedure for each channel you want to program.
Storing Frequencies into Channels
