Using Signal Stalker Ii With Lockout - Radio Shack 20-427 PRO-2054 User Manual

Beyond the Basics

using signal stalker II with lockout

The scanner's lock out feature can be used to
bypass unwanted transmissions while using the
Signal Stalker II. Press L/OUT when the scanner
is stopped on an undesired transmission.
Press FUNC L/OUT to review or clear locked out
frequencies in the Signal Stalker II. You can lock
out 150 frequencies while searching all bands
and 50 frequencies while searching Police/Fire
frequencies.
Signal Stalker II functions by rapidly sweeping
through the RF spectrum in 1 MHz segments. If
RF signal energy is detected in a 1 MHz segment,
Signal Stalker II will sweep through the 1 MHz
segment in fi ner steps until the source of the RF
signal energy is found.
Certain segments of RF spectrum are used
by high power transmitters, such as paging
transmitters. The Signal Stalker II can detect these
transmitters easily, even at great distances due to
their high transmitter output power. You can press
L/OUT when the Signal Stalker II stops on these
undesired transmissions to prevent the Signal
Stalker II from stopping on them in future sweeps,
however, the Signal Stalker II will still see their
RF signal energy when sweeping through the 1
MHz segment. This will cause the Signal Stalker
II to execute another fi ne step search of the 1
MHz segment. Of course, if you have locked out
the undesired transmissions, the Signal Stalker II
will not stop on them again, however, the overall
sweep performance of the Signal Stalker II will be
impacted.
