, ,or turns OFF. Any group that is not in a trunked system group scan
list will show a "blank" for the time out period when it is the selected channel.
Nuisance Delete
A group can also be deleted from the scan list, if it is not the currently selected
group, by pressing the
key (Scan model) or the key (System model)
during scan operation while the radio is displaying the unwanted group. The
group will be deleted from the system's group scan list in the same manner as
if done using the steps above. Deletions done in this manner will not remain
deleted if the radio is powered OFF and then powered ON.
SCANNING TRUNKED SYSTEMS
The radio can be programmed with the following System Scan features. These
features are automatically enabled when the radio is powered ON. A key or
menu option is also defined to allow the System Scan features to be toggled
during radio operation. This is covered in the Menu Selection and Pre-
Programmed Keypad Key sections. The System Scan state will be maintained
through system changes but will default to ON when the radio is powered ON.
Wide Area System Scanning
The P7200 series radios can be programmed for Wide Area System Scan
operation for roaming across mobile systems. Upon the loss of the currently
selected system's control channel, radios can be programmed to automatically
scan the control channels of other systems. If a new control channel is found,
the radio will switch to the new system and sound an alert tone.
Priority System Scan
The radio can also be programmed for Priority System Scan. The priority
system is the desired or preferred system. While receiving the control channel
of the selected system, the radio will periodically leave the selected system
and search for the control channel of the priority system. This is done at a
programmable rate defined by the value in the Priority Scan Time control
(unless the ProScan
algorithm is enabled, as explained in the following
sections). This priority scan timer is reset each time the PTT button is pressed
or when the call is received. If the priority system control channel is found, (or
meets the predefined criteria <ProScan>), the radio will automatically switch
to the priority system.
Enabling the Wide Area System Scan Function
If the radio cannot find the control channel of the selected system and begins
to wide area system scan, the radio will only scan for the priority system
control channel if the priority system is in the wide area scan list.
