GM1600 marine VHF handheld device is specially designed to meet GMDSS requirements for survival craft communication. The radio has been carefully designed to survive and operate normally under extreme environmental conditions common in maritime emergencies, and to bring the latest search and rescue technology to the market. The shock-proof shell of GM1600 is made of bright dye-infused polymer, ensuring that the emergency equipment can be easily found in life-saving bags, life rafts or other places that need to be quickly discovered. It meets the strict radio environment requirements of the survival craft IC-GM1600, and can meet the requirements of temperature, thermal shock, vibration and anti-fall (starting from a height of 1 m). After passing these environmental tests, IC-GM1600 retains the 1 m depth waterproof structure specified by IMO resolution A.694 (17), MSC149 (77) and related specifications. The lifeboat walkie-talkie GM1600 meets the requirements of temperature, thermal shock, vibration and drop resistance (starting from a height of 1 m). After passing these environmental tests, GM1600 can withstand the 1m depth waterproof structure specified by IMO resolution A.809 (19), A.694 (17) and IEC 61097-12.
