4.1 Contact for support
Contact your authorized dealer for technical service and support of the VHF radio. Before

some of the most common operational problems.
4.2 Maintenance
4.2.1 Preventive maintenance
Maintenance of the SAILOR 6222 VHF DSC can be reduced to a maintenance check at each
visit of the service staff. Inspect the radio 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.
Salt deposits
In case the equipment has been exposed to sea water there is a risk of salt crystallization on
the keys and knobs and they may become inoperable. Clean the VHF radio and speaker
microphones with fresh water.
4.2.2 Error messages and warnings
Errors and warning messages are shown in the display and are read-only.

call to be the same as the transmitted.
The display shows the result of the test.
