Retevis RM40 Marine Radio is the latest generation radio in VHF mode. Compared to the other models, it has a
richer panel with a high-definition screen and many functions that are activated directly from the buttons
without searching the menu.
With the carefully calibrated squelch function that effectively reduces ambient noise, the RM40 has improved
sound quality that is essential in communications aboard boats, helicopters and flight bases.
Another highlight of the RM40 is the addition of the DSC alarm function, which makes the portable marine
radio more practical; in the event of an emergency, the operator can directly send its geographical position
and alarm information to surrounding ships or coastal radio stations, which can initiate first aid.
