Initiating a Group Call
If the portable has Scan enabled when the site enters ISO, the portable will be
able to initiate a call on its Primary Talkgroup and can respond to calls started
on either the Primary or any Secondary Talkgroup.
The portable will not be able to select a new Talkgroup
Mode while in ISO condition.
If the portable has Scan disabled when the site enters
ISO, the portable will be able to initiate and respond to
calls on the Primary Talkgroup only.
Exiting ISO
When the cell returns to normal operation, the unit will
revert back to standard operation. The green LED
indicator will resume blinking.
If the unit goes out of range of the ISO cell and has no
available neighbor cells, the unit will go out of service.
Other Operations
Since the ISO operation is limited to group calls only, any attempts to
communicate in other modes (phone, private, alert, status) will result in a
"Service Not Available" message. However, all other functions (memory scroll,
direct entry, feature menu programming, etc.) are still operable.
