3.2.2 Manuals
Only a single operations manual covers all VHF Series 5000 transceiver models. Software updates might add
new features to the product, even if the upgrade is free of charge. In the service message sent out with new
software releases, there might be a recommendation to also update the manuals on board the vessel.
3.2.3 Service tool
The SB5006 service tool is compatible with all models of the SAILOR VHF 5000 Series equipment. The tool is
the single equipment needed for updating and configuration of the RT5022/RT5020 transceiver software.
3.2.4 Service concept – RT502x VHF DSC main unit
The service and repair concept of the RT502x VHF main unit may be divided into two situations, namely onboard
repair and workshop repair. The two differs mainly in that specific workshop measurement devices for the
verification of certain equipment performance parameters will not be available for onboard service - and to some
extend the often limited time available onboard to perform the repair.
Onboard service & repair:
The onboard service & repair, besides the VHF equipment itself encompasses also the part of the ship’s
installation pertaining to the operation and performance of the VHF equipment, i.e. antenna installations,
associated cabling, ships power supply, external power supply units etc. all of which must be in correct and
proper condition to enable the proper function and performance of the VHF installation.
In terms of equipment repair this may be accomplished in different ways and levels, depending on the available
time for the repair, available parts, technician’s knowledge of the equipment etc. Fast and effective equipment
repair will be accomplished through replacement of pre-tested base unit or front assy’. replacement.
