Contact for support
Contact your authorized dealer for technical service and support of the VHF
radio. Before contacting your authorized dealer you can go through the
troubleshooting guide to solve some of the most common operational problems.
Maintenance
Preventive maintenance
Maintenance of the SAILOR 7222 VHF DSC can be reduced to a maintenance
check at each visit of the service staff. Inspect the radio (Control Unit and
Transceiver) for mechanical damages, salt deposits, corrosion and any foreign
material. Due to its robust construction and ruggedness the radio has a long
lifetime. Anyway it must carefully be checked at intervals not longer than 12
months - dependent on the current working conditions.
DSC self test
To run a control routine DSC self test, do as follows:
1. Tap DSC TEST from the idle screen (Home) or, if you are in a DSC session,
tap MORE and then DSC TEST.
The test will check the ability to encode/decode DSC signaling on RF level.
The radio will automatically transmit a DSC safety test call to its own MMSI
number without enabling the transmitter power amplifier. In parallel the
radio decodes and compares the received call to be the same as the
transmitted. The display shows the result of the test.
2. Tap OK to acknowledge the test result and resume normal operation.
If the DSC loopback test fails, this indicates the DSC functionality
does not work correctly — including the ability to send a distress
message.
Contact your dealer immediately for further advice.
