SENDING A DIRECT-DIAL CALL, INFO
To save the call select SAVE and press the Enter button.
Acknowledgement from the coast station is normally received within 25 sec.
If the coast station cannot comply immediately with the call request due to the appropriate working
frequencies being busy or for other reasons, this will be indicated in the acknowledgement.
The coast station evaluates the working channel quality during the DSC call. If quality is satisfactory
the acknowledgement contains the same working frequencies. The coast station then starts dialling
the subscriber.
If the working channel quality evaluation indicates that quality is not satisfactory the coast station may
suggest other working frequencies. In this case the DSC calls are repeated on the new working
frequencies.
If the working channel quality evaluation again indicates that quality is not satisfactory and no other
channels are available the coast station sends an acknowledgement indicating -Cannot use Channel-.
