Marine VHF DSC Radio Telephone

Product Name :
CZ-M580C Marine VHF DSC Radio Telephone

Description of the Product:
This product is an advanced new-generation multifunctional A-type VHF DSC radio telephone, which is well-designed based on the standards of CCIR 493-4 Technical Characteristics, CCIR 541-3 Operational Characteristics and A.803 (19) under ITU-R Proposals issued by the International Radio Consultative Committee, and the national regulations, with the purpose to achieve the high stability and easy operation based on combination of actual application.
In addition to the aluminum frame as the main construction, this product adopts high-quality components and waterproofing measures, using appropriate software and hardware circuits, as well as the large-screen LCD Chinese display.
A DSC 70CH dedicated channel is fitted to avoid not receiving DSC call signals during a call.
And a high-performance FM (88-108MHz) radio is installed additionally in accordance with the actual needs of customers, which makes it easy to listen to weather forecasts. In the case that GPS signals are connected, a navigation display can be achieved, the azimuth and the distance for the destination point can be calculated automatically, and the current course and speed can be displayed, which will make the navigation easier.
