DSC OPERATION
■ Transmitting DSC Calls (Continued)
D Test call
Testing on the exclusive DSC distress and safety calling
channels should be avoided as much as possible by using
other methods. When testing on the distress/safety channel
is unavoidable, it should be indicated that these are test
transmissions.
Normally the test call would require no further
communications between the two stations involved.
