Samyung SUR-350

Samyung SUR-350  is a river radio station designed specifically for operation on river vessels as the main and operational station. The radio supports all simplex and duplex communication channels used for GDP, and fully complies with the standards of the Russian River Register. Samyung SUR-350 can be called a device of a new generation, after all, in a rather small case of a walkie-talkie there is a receiver and a transmitter of the range 300? 337 MHz, station controls with a keyboard and a display, as well as an interface for connecting external equipment. 

Samyung SUR-350 is equipped with a large clear LCD display with a wide viewing angle, which reflects all relevant information. The display has two levels of illumination, so the walkie-talkie can be used even in the dark. In addition, there is a built-in adjustable squelch, so the signal will always be clear. 
     
  • The equipment meets the requirements of the IMO Standard, CCIR.
  • Since the compact housing includes an integrated transceiver, it can be easily installed anywhere.
  • UHF radiotelephone station SUR-350 has a large backlit LCD display with a wide viewing angle.
  • In addition to this, all instructions for the operator are displayed on the screen for convenient operation.
  • The brightness of the backlight of the screen is easily adjustable, which makes it easier to observe work at night.
  • The SUR-350 contains several TAG SCAN scan modes, ALL SCAN, and DUAL WATCH, which makes it convenient to monitor the desired channels.
  • The device is waterproof.
  • Selection of functions for high (High) or low (Low) transmission power and automatic installation.
  • The CH5 button is for quick access to the security channel.
