Decide whether you want to lock out a system, site, or channel so the scanner will ignore it during Scan and Search modes. If you lock out a system or site, all channels within that system or site will be locked out. Choose one of the following options: 
-  Unlocked: The system, site, or channel is not locked out.
  -  Temporary L/O: The system, site or channel is locked out until you turn the scanner off and back on.
  -  Lockout: The system, site, or channel is permanently locked out.
