Note:
If either entered frequency is incorrect,
“Invalid
Freq”
appears briefly.
6. Press SRCH to start searching.
7. Adjust the squelch. After the set delay, the scanner starts
searching. When the scanner finds an active frequency, it stops
searching.
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 (
) for approximately 1
second.
2. To change the scanned band (All Band or PubSafety Band),
press FUNC then Signal Stalker (
).
For a list of Signal Stalker bands, see “Appendix D” on page 61.
3. To turn off a bank, press the bank or group number while Signal
Stalker II is active.
4. To turn off Signal Stalker, hold the Signal Stalker button (
)
again.
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 S or T.
“Sp. Stalker”
appears for Special Signal Stalker
II.
3. To turn off Special Signal Stalker II, press FUNC and then S or
T again.
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
more,
“L/O Memory Full!”
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.
