A few notes about the frequency download order:
1. The scanner fills up less than its allotted 300 channels if
there are not more than 300 of the above types of licenses
in your area.
2. If there are more than 300 of the above listed types of
licenses, or you have locked-out some banks prior to the
download using the Program Lock feature, the scanner
may run out of memory locations and you may not, for
example, receive part or all of your county, state or
nationwide data.
3. If you wish to also receive a download of frequencies
and talk groups from an adjacent county, lock those banks
you wish to keep, shut the scanner off, turn it back on
again and enter the SmartScanner download mode. Then
enter a zip code from a community within the adjacent
county.
4. The SmartScanner editors used their best efforts to
delete digital and MDT (mobile data terminal) computer
records from the database; however, it would be
impossible to delete them all. Therefore, you may hear
some non-voice transmissions on the frequencies
downloaded into your scanner. Make sure you have
TRUNK mode on to see if these are control channels for a
trunking system. If not, then you should lock these
frequencies out or delete them by entering a new
frequency or entering 0, .
5. Important: After the download, be sure to press the trunk
key to see if you have trunk systems now loaded for your
area. The BC 245XLT cannot track such systems unless
the trunking mode is on. Performance of the scanner is not
hindered if you have TRUNK mode on and you do not have
a trunk system programmed.
6. If you have a trunk system programmed (you can tell by
seeing if the display shows Id SCAN at any time), be sure
to put the radio into Trunk Search mode at some point to
discover new talk groups within the trunk system that
have not been pre-programmed into the
SmartScanner database.
7. The database will be updated every 6 to 12 months at
a minimum.
