Programming a Search Range
To program the search range of Bank SR7:
1. Repeatedly press SRCH to select SR7.
2. Press PROG then SRCH. “Enter SR7
Search Range Limits” appears.
L blinks for the lower-limit of the range.
3. Use the number keys to enter the lower-
limit frequency (including the decimal
point).
4. Press ENT. U blinks for the upper-limit of
the range.
5. Use the number keys to enter the upper-
limit frequency (including the decimal
point), then press ENT.
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 67.
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.
