Signal Stalker II

Signal Stalker II provides a powerful tool to rapidly detect, monitor
and save frequencies of nearby or high-power transmissions. Signal
Stalker II resembles more expensive portable frequency counters,
but provides many advantages over typical portable frequency
counters.
Signal Stalker II is more sensitive than portable frequency counters
and will detect transmissions at a greater distance. Signal Stalker II
rapidly searches the RF spectrum in 1 MHz segments. If it detects a
signal, Signal Stalker II searches in finer steps until the signal source
is found.
Signal Stalker II can search all frequencies, or you can define
frequency ranges, to avoid ranges with constant activity, such as
paging or broadcast transmitters.
To use Signal Stalker II:
1. Hold the Signal Stalker button (
second.
2. To change the scanned band (All Band or PubSafety Band),
press FUNC then Signal Stalker (

Note: Priority mode is not available while using the Signal
Stalker II.

Special Signal Stalker

Special Signal Stalker II divides the frequency range by 1 MHz
segments. If you lock out 5 frequencies within 1 MHz segment, the
scanner will skip that segment in subsequent sweeps.
To use Special Signal Stalker II:
1. Press FUNC while Signal Stalker II is active.
2. Press or . "Sp. Stalker"

3. To turn off Special Signal Stalker II, press FUNC and then

Locking Out Frequencies

When you lock out frequencies during a search, the scanner
continues searching, but ignores the locked out frequencies. You
can lock out up to 50 frequencies in each bank. If you try to lock out
"L/O Memory Full!"
more, appears.
While using Signal Stalker II, you can lock out 150 frequencies if
searching All Bands and 50 frequencies while searching PubSafety
frequencies. If you lock out 5 frequencies within a 1 MHz segment,
the scanner will skip that segment in subsequent sweeps.
