Test Calls; Making A Test Call; Receiving A Test Call - Raymarine RAY90 Installation And Operation Instruction Manual

7.10 Test calls

A Test Call feature is available for the purposes of testing your DSC VHF radio for correct operation.
There are 2 types of test call:
• Test call to the US Coast Guard automated response test call service (MMSI: 003669999). This
type of test call will receive an automated response (acknowledgement).
• Test call to another vessel that has a radio that supports the test call feature. Your radio will
automatically acknowledge test calls received from other radios.
For radios that do NOT support the test call feature, correct radio operation can be tested by making
an Individual call on channel 70 to another DSC VHF radio.
It is recommended that once you've successfully placed a test call you add the test call MMSI to your
radio's Phonebook for easy retrieval for future test calls. For information on how to add an MMSI
to your radio's Phonebook.
Note:
Individual calls (that is, NOT a test call) to the US Coast Guard 003669999 MMSI will NOT receive
an automated response.
Note:
The US Coast Guard automated response test call service is only available in the United States
and its coastal waters.
