These are private (not secret) calls made between one radio user and another. In most instances all these calls would be within the same fleet. Should calls be required to be made between fleets, additional interfleet and interprefix codes will have to be entered.
When the call is made, an indication of the availability of the called party is given i.e. busy, available or not available.
The length of the call will be limited to ± 3 minutes as set by the system manager.
