Displaying Memory Usage
Your scanner can report how much free memory is available for new objects,
and show how much memory has been used, and how the memory is al-
located to different types of objects. To display the memory usage report,
use the power-on shortcut by pressing 0, then 0 again while the Welcome/
Owner screen is displayed just after the radio is powered on, or, press PGM,
then the
GLOB
softkey to access the Global configuration menu, then scroll
down using the
6
key until
Memory Info:SEL
appears in the display.
Press SEL to view the memory usage report. Use the
56
keys to scroll the
display.
Search Object Types
A very powerful feature of your PSR-310 is the ability to define different types
of frequency searches and process them while scanning. Frequency search-
es are just another type of Scannable Object in the hierarchy of the radio's
memory organization, so they can be manipulated and scanned in the same
manner as conventional channels and trunking talkgroups.
There are several different types of frequency searches available in your
scanner.
Limit Search Object (LMIT)
A Limit Search Object (LMIT) is a search object that stores the parameters
necessary for the radio to search each frequency within a lower and an up-
per limit for activity. A LMIT object can be used for standalone searching -
the radio just searches and stops when activity is detected on a frequency,
or for searching that is performed while the radio is scanning. The radio
treats LMIT objects just like any other Scannable Object when in Scan Mode.
If you create a LMIT object, assign it to a Scan List and press the SCAN key,
the radio will check for activity on all the Scannable Objects - TGRP objects,
CONV objects, and even LMIT objects. An example of when this might be
handy would be when you want to scan for activity on a collection of TGRP
and CONV objects, then run through a range of frequencies to look for activ-
ity there, such as the entire 2 meter amateur radio band or the entire VHF
marine radio band. When used in Scan Mode, this capability is best suited
for small ranges of frequencies that contain more frequencies than practical
to program as individual channels. Any size range can be used, but larger
ranges that take more time to search will increase the chances of missed ac-
tivity on other object types.
Essential Limit Search parameters
Much like the other object types, there are only a few parameters that are
essential in order for a search range to function correctly. The
FrLO:
and
FrHi:
lower and upper frequency limits must be specified, so the scanner
will know where to begin the search, and where to end the search and start
again. The
Modulation:
must be set properly, although by default the
