User's Manual

To delete an object, press PGM, then use the <>^v keys to navigate to the object you wish to delete. Press
FUNC CL to delete the object. The scanner will ask you to confirm the delete command before removing
the object from the scanner's memory. Deletions cannot be un-done.
To delete a TSYS, use the FIND feature to search for the TSYS by name. Press PGM, then press the EDIT
softkey, then press the FIND softkey, and use the Standard Text Entry Method to enter all or part of the
TSYS name you wish to delete. Press the OK softkey to begin searching, and, if necessary, press the
NEXT softkey to continue searching until the desired TSYS is located. Once the TSYS has been located,
press the PGM key, then press FUNC CL. The scanner will ask you to confirm the delete command before
removing the object from the scanner’s memory, then, provide a final warning that all TGRPs associated
with the TSYS to be deleted will be lost if you proceed. Press the YES softkey at both warnings to delete
the TSYS.
An alternative method is to browse TSYS objects only using the TSYS filter. Press PGM, then the EDIT
softkey, then >>>, and press the TSYS softkey. Scroll to the desired TSYS using the ^v keys, then press
FUNC CL. The scanner will ask you to confirm the delete command before removing the object from the
scanner's memory, then, provide a final warning that all TGRPs associated with the TSYS to be deleted will
be lost if you proceed. Press the YES softkey at both warnings to delete the TSYS.
Using Multi-Site Mode On Networked Systems
Some Motorola systems include a large number of sites that are networked together to provide radio
coverage to a large geographical area. These types of trunked radio systems are more commonly used for
large statewide systems, and for some systems that are used in large, rural counties.
These networked trunked radio systems work in a manner that is very similar to a cellular telephone
network. As a system user moves around (or “roams”) in the coverage area of the network, their radio will
automatically find and use the nearest tower site. Each tower site includes a number of channels. One of
these channels is used for control channel data, and the remaining channels are used for voice traffic. As a
user moves away from the coverage of one site, their radio will search other control channel frequencies for
a better site to use.
Your PSR-310 includes a Multi-site feature that can enhance the operation of the scanner when monitoring
Multi-site systems. Multi-site can be enabled by editing the trunking system (TSYS) parameters for a
Motorola system. Multi-site can be set to Off, Stat (Stationary) or Roam. By default, Multi-site is set to OFF.
The ROAM setting is ideal for those times when you are driving around in the service area of a networked
trunked radio system, as it allows the radio to find and use the best tower sites as you move in and out of
the coverage footprints of different sites. The STAT(ionary) setting is ideal for those times when you are not
