Appendix A: Glossary

Frequency – The signal (expressed in MHz)
used by broadcasting radios. To find active
frequencies, you can use frequency guides
available from your local RadioShack store,
frequency lists posted on the Internet, or your
scanner's search function.
Bank – A storage unit for a group of channels.
A channel contains one frequency, and a bank
can hold up to 100 channels.
Channel – A programmable memory locations
for a single frequency.
Talk Group ID – A simultaneous trunking
transmission that identifies 2-way radio users.
This allows trunking systems to allocate a few
frequencies to multiple 2-way radio users.
Sub-bank – Each bank has an associated
Talk Group ID sub-bank. In Closed mode, the
scanner only stops if a transmission has a Talk
Group ID saved in the associated Talk Group
ID sub-bank. In Open Mode, the scanner stops
on all transmissions, except those you lock out.

Appendix B: Search Banks

All scanners tune by steps. Your RadioShack
scanner uses steps consistent with the latest
US or worldwide standards. If you enter a
non-valid step frequency, any scanner will
tune to the next step. Some scanner designs
do this without showing the correct step in
the display. This scanner will show the actual
tuned frequency in the display. Because steps
are so close together, the audio quality will
not be affected by the offset.
