MF/HF MARINE TRANSCEIVER

GM800

Reliable Performance for MF/HF Long Distance Communication

This model is currently being recertified to the latest MED Directive. 
Please consult with your local regulatory authorities regarding installation and/or “Wheelmark” requirements.

Satisfies SOLAS Carriage Requirements

The GM800 meets the GMDSS (Global Maritime Distress and Safety System) VHF and MF/HF radio requirements as required for SOLAS regulated commercial vessels engaging in international voyage. The radio meets the MED, "wheel mark" requirements for European merchant ships.

Meets Strict Environmental Requirements

The GM800 have passed rigorous environmental testing and quality assurance processes. These radios are designed to provide reliable operation and long-lasting durability under harsh maritime environments. In fact, the controller has IPX7 protection (1 m depth of water for 30 minutes).

Meets ITU-R M.493-13 DSC

DSC Task mode screen

The dedicated DSC watch-keeping receiver continuously scans the six distress channels in rotation. A total of 100 MMSI members for DSC calls can stored with a 10-character ID name. The DSC Multitask function shows up to seven DSC procedures. The GM800 is also capable of sending a distress relay call.

4.3 inch Wide Viewing Angle Colour Display

The 4.3 inch colour TFT LCD provides almost 180 degree wide viewing angle and displays high resolution characters and function icons. Even when the radio is installed to the instrument panel, the operator can clearly recognize the display information from various viewing angles. The night mode display ensures good readability in low light conditions.

Provides Loud, Clear Audio

By adopting a new waterproof paper speaker cone, the speaker provides superior sound quality and a flat frequency response with a wide frequency range.

Unified Design User Interface

The GM800 (MF/HF) and GM600 (VHF) have a unified design and offer consistent operation. A combination of the directional keypad and soft keys provides simple operation. Most used functions are assigned to soft keys (at the bottom of the display) for quick one push function access. The large ten-key pad enables you to smoothly enter channel numbers, MMSI numbers with ID names and so on.
