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 1MHz segment in finer 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 fine 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.
Signal Stalker II features a special lockout mode that causes the scanner to skip a 1 MHz
segment if five or more lockouts exist in that 1 MHz segment. To activate this mode, press
FUNC /¥ while in the Signal Stalker II mode. If a 1 MHz segment contains 5 or more
lockouts it will be skipped entirely while Signal Stalker II is sweeping. Use FUNC L/O to
review or clear locked Signal Stalker II frequencies.
To clear a locked-out frequency, select that frequency, then press CLEAR.
using delay
Many conversations might have a pause of several seconds between a query and a reply. To
avoid missing a reply, you can program a 2-second delay into any of your scanner’s channels.
Then, when the scanner stops on the channel, DLY appears and the scanner continues to
monitor the channel for 2 seconds after the transmission stops before it resumes
scanning/searching. The delay feature is also available while searching.
