2-18 FEATURES AND BENEFITS
If you program the radios for Busy Channel Lockout on Busy Channel, only one member of the
security team will be able to transmit at any time. This conÞguration would prevent a member of the
security team from transmitting when ANYONE else is transmitting, regardless of whether the
transmitter is another security guard or someone from one of the shops.
If, however, the customer wishes to allow his team members to interrupt each other (eg. "break
through" an ongoing conversation in the event of an emergency) then you would programme the
radios for Busy Channel Lockout on Wrong PL. This conÞguration would prevent a security guard
from talking over somebody from another organization, but would permit talking over another
security guard.
3.4.6 Scanning
Scanning greatly simpliÞes the operation of the radio for those of your customers who have multiple
channel systems. This feature ensures that incoming calls are not missed, even when they originate
from more than one channel.
The ability to start and stop Scanning can be assigned to one of the programmable side buttons,
allowing the radio operator to use scanning when it is most appropriate.
Alternatively, on a P080 model, Scanning can be started and stopped using the menu and
navigation keys.
The beneÞts that your customers can derive from the Scanning-related features are summarised in
the following table.
The remainder of this sub-section provides a more detailed description of the Scanning-related
features and beneÞts.
A "Scan List" consisting of the channels that should be monitored for activity is programmed into
each radio. A different Scan List can be assigned to each channel personality, with each Scan List
capable of containing up to 16 different member channels.
When scanning is activated, the radio automatically cycles around each channel in the list checking
for relevant voice activity. While searching for activity, the radio is said to be in "Active Scan Mode"
