want to call. Enter the MMSI number the same way you enter directory 

entries (see page 27). Enter all nine digits and press the

are about to call and asks you to confirm. 

If you want to call the displayed MMSI 

number, select Send. To cancel the call, 

select Cancel.
The radio automatically switches to chan-

5. 

nel 70 to transmit the test call request, 

then switches back to the last-used channel.

You can use the test call feature to make sure your radio is working and 

configured correctly. To avoid overloading coastal receiving stations, you 

should limit test calls to these stations to once a week. 
NOTE: Many coastal stations have specific frequencies and MMSI numbers 

you should use for making test calls. Be sure to check with the coastal station 

before making a DSC test call.
