scanner will automatically choose the receive mode that most likely applies
to the active frequency as the search proceeds. And again, we recommend
that you give the LMIT object a name in the
Tag:
field so that you can eas-
ily find or identify it later.
To create a new LMIT object, press PGM to place your scanner into Program
Mode, then press the
NEW
softkey, then press the
SRCH
softkey to view
the available Search types, then press the
LMIT
softkey. Use the data en-
try methods you have already learned for CONV and TGRP object setup to
specify the
FrLO:
and
FrHi:
limits, and provide a name for your search
in the
Tag:
field. When finished, press the
Save
softkey to store your
LMIT search as a new object.
Once your LMIT object is saved, you can use it while scanning, or launch
the LMIT search by itself by pressing the
SRCH
softkey (note that we are
referring to the
SRCH
softkey, and not the SRCH key on the keypad) after
navigating to the LMIT object in Manual Mode.
When the LMIT search stops on an active frequency, the display will appear
as follows:
Press the PSE key to hold on the active frequency. To resume, press the
PSE key again.
HINT: It can take some time for the PSR-310 to process all of the frequencies
in a LMIT search. You can experiment with different size frequency ranges to
find a LMIT search setup that does not interfere excessively with scanning of
other object types.
Spectrum Sweeper Object (SWPR)
A Spectrum Sweeper Object (SWPR) is a record that stores the parameters
necessary for the radio to rapidly sweep a range of frequencies for strong
signals from nearby transmitters. A SWPR object can be used for standalone
operation - the radio just sweeps and stops when activity is detected, or
for sweeping that is performed while the radio is scanning. The radio treats
