VHF radio with DSC Class A
Exceeding standards set by IMO regulation for GMDSS Class A VHF, the August
2021 introduced Bridge Alert Management IMO resolution MSC.302(87), as well
as IEC 62923-1 & IEC 62923-2, the SAILOR 7222 VHF DSC Class A is a robust
platform for when clear communication could make the difference between a
non-event and a major incident.
As part of the required safety
equipment, use the SAILOR 7222
VHF DSC in an emergency
situation. However the best way to
guarantee functionality in an
emergency situation, is to use the
radio in daily communication on
board.
The VHF radio is a simplex/semi
duplex VHF radio consisting of
two units connected with a
standard Ethernet cable:
• SAILOR 7224 Control Unit
• SAILOR 7226 VHF Transceiver
Unit
It is designed with an easy-to-use menu-driven setup. You use the touch screen
on the SAILOR 7224 Control Unit or a connected device with a browser to enter
the desired functions. You can also select channels using the rightmost selection
knob. The large display can be customized for optimum readability and visibility
both day and night with different color themes.
The VHF radio can replay 480 seconds of received voice messages. This is a
useful feature to minimize misunderstandings and to record messages when the
radio is unattended.
With SAILOR connection boxes the VHF radio connects easily to external
equipment like a BAM system, additional handsets, water proof hand
microphones, control speaker microphone, alarm panel or external speaker. The
