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.
scanning the channels
To begin scanning channels or to start scanning again after monitoring a specific channel, press
SCAN.
Notes:
. You must store frequencies into channels before the scanner can scan them. The scanner does not
scan through empty channels.
. To change the scanning direction, press /¥ or ¥/.
The scanner scans through all channels (except those you have locked out) in the active banks (see
“Turning Channel-Storage Banks Off and On” and “Locking Out Channels or Frequencies”).
turning channel-storage banks off and on
To turn off banks while scanning, press the bank’s number key so the bank’s number disappears.
For example, to turn off bank 1, press 1. The scanner does not scan any of the channels within the
banks you turned off.
To turn on banks while scanning, press the number key until the bank’s number appears. For
