Zeromatic Tuning
Zeromatic tuning is a feature that enhances the scanner's ability to lock on to the actual center frequency of a
search hit instead of an adjacent frequency. This option is available for all Limit, Service, and Stalker/Sweeper
search objects and dedicated searches except CB, Marine, and F/G/MURS.

Signal Stalker/Spectrum Sweeper Search
Your scanner's Stalker/Sweeper feature provides a powerful new tool for you to rapidly detect, monitor, and store frequencies from
nearby
radio
transmissions. The Stalker/Sweeper feature is more sensitive than portable frequency counters and will detect transmissions at a greater distance.
Stalker/Sweeper functions by rapidly searching through the RF spectrum in 1 MHz segments. If RF signal energy is detected in a 1 MHz segment, the
scanner will search through the 1MHz segment in finer steps until the source of the RF signal energy is found. The Stalker/Sweeper feature is similar in
functionality to portable frequency counters that cost much more than your scanner, but provides many advantages over typical portable frequency
counters. For example: The Stalker/Sweeper allows you to search the entire range of your scanner's design frequencies, or you can specify just those
frequency ranges that you wish to search.
Stalker/Sweeper Search
Special Stalker/Sweeper Search
Special Stalker/Sweeper
If a 1 MHz sweep indicates that activity is present, when set to 'On' (
F2
-
SPCL
),
Special
Stalker/Sweeper searches the whole 1 MHz range to find the
source. If you lockout 5 frequencies within a 1 MHz segment, the scanner will skip that entire segment in subsequent searches. See
(in the '
Expert Settings
' menu) to change the (default
5
) number of frequencies within a 1 MHz segment.
You can press
F1
(
FrL/O
) when the Stalker/Sweeper stops on these undesired transmissions to prevent the Stalker/Sweeper from stopping on them in
future searches, however, the Stalker/Sweeper will still see their signal energy when searching through the 1 MHz segment. This will cause the
Stalker/Sweeper to execute another fine step search of the 1 MHz segment. If you have locked out the undesired transmissions, the Stalker/Sweeper will
not stop on them again but the overall search performance of the Stalker/Sweeper will be slowed accordingly.
Programming your
Stalker/Sweeper Sea
rch as an object
gives you more options for the
search (delay time, LED mode/color/latch, alarm, etc.). This will also allow you to program
different Stalker/Sweeper objects with different settings and assign them to one (or more)
of the 22 Scan Lists.
