We want to take a couple of moments of your time to structions for the IC-M801E. thank you for making the IC-M801E your radio of choice, and hope you agree with Icom’s philosophy of EXPLICIT DEFINITIONS “technology first.”...
IN CASE OF EMERGENCY When your ship requires assistance, contact other ships and the Coast Guard by sending a distress call using dig- ital selective calling on an emergency frequency. When immediate help is needed When potential problems exist q Push and hold [DISTRESS] for 5 sec. until the q Push [DSC] to select DSC watch mode, if neces- short beeps become one long beep, to send the sary.
