guide to solve 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.

Errors and warning messages are shown in the display and are read-only.
