Once the TSYS has been located, press the 
PGM
 key, then press
FUNC CLR. 
The scanner will ask you to confirm the delete 
command before removing the object from the scanners
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 
 keys, then press 
FUNC CLR.

Using Multi-Site Mode On Networked Systems
Some Motorola and P25 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 0716 includes a Multi-site feature that can enhance the 
operation of the scanner when monitoring Multi-site systems. 
Multi-site can be enabled editing the trunking system (TSYS) 
parameters for a Motorola or P25 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 
moving and are within range of more than one tower site, as it
