About Your Scanner - Radio Shack PRO-94 Owner's Manual

ABOUT YOUR SCANNER

We use a few simple terms in this manual to explain the
features of the PRO-94. Familiarize yourself with these
terms and the scanner's features and you can put the
scanner to work for you right away. Simply determine
the type of communications you want to receive, then
set the scanner to scan those communications.
The PRO-94 scans conventional frequencies and
trunked systems . For more information about trunked
transmissions see "Trunking Operation" on Page 41.
A frequency, expressed in kHz or MHz, is the tuning
location of a station. To find active frequencies, you use
the search function or refer to a frequency reference
such as the included Trunking Frequency Guide .
Besides searching within a selected frequency range,
you can also search your scanner's service banks .
Service banks are preset groups of frequencies catego-
rized by the type of services that use those frequencies.
For example, many amateur radio frequencies are lo-
cated in the service bank.
HAM
When you search and find a desired frequency, you can
store it into a programmable memory location called a
channel . Channels are grouped into channel-storage
banks . The PRO-94 has 500 channels in channel-stor-
age bank A and another 500 in channel-storage bank
B. Each bank of 500 is divided into ten 50-channel sets.
You can scan the channel-storage banks to see if there
is activity on the frequencies stored there.
Or, when you find a frequency, you can store it into a
temporary memory location called a monitor memory
until you decide whether or not to move it to a channel.
Just keep in mind — you search frequencies and scan
channels.
