To call another station, just enter that station’s MMSI number and choose the voice channel you want to talk on. The radio uses channel 70 to transmit your MMSI number to the other station along with the voice channel you requested. If the other station accepts your call, both radios automatically switch to the requested voice channel so you can talk to the other station. DSC provides a system for automated distress calls. At the touch of a button, the radio can transmit your MMSI number, the nature of your distress, and your current position based on data from your GPS receiver. The radio repeats the distress call every few minutes until it receives an acknowledgement. The DSC standard dedicates a VHF channel—channel 70—to digital transmissions only. Since digital transmissions require less bandwidth voice transmissions, channel 70 avoids the problems of busy voice channels. Your radio supports the following DSC features: Feature Menu Item FunctionIndividual Call Individual Contact another vessel from your directory.Group Call Group Contact all vessels that share your group MMSI code.

There are two kinds of MMSI numbers: individual numbers for use by single boats and group numbers for use by eets, boating organizations, event coordinators, etc. You can get more information on MMSI numbers at these resources: xThe dealer where you purchased the radio xRecreational boaters can obtain an MMSI number from the Boat Owner’s Association of the U.S. (http://www.boatus.com/mmsi/ or call 800-536-1536) or Sea Tow Services International (http://seatow.com/boating_safety/mmsi.asp) xCommercial boaters need a ship station license to get an MMSI number. For more information, visit the Federal Communications Commission (FCC) website at http://wireless.fcc.gov/marine/ fctsht14.html. Entering MMSI numbers Use the Channel Up and Channel Down keys to scroll through numbers (and letters when entering names). When you see the number/letter you want, press the right arrow (GPS/MEM) to move the cursor to the next space. Press the left arrow (WX/SOS) to back up.When using the Channel Up and Channel Down keys to enter a name, the alphabetic and numeric characters display in the following order: xCapital letters (A through Z) xLower-case letters (a through z) xPunctuation (/ ‘ + -) xNumbers (0 through 9) xOne blank space

Here are a few guidelines that affect nearly all boaters.• If you have a VHF radio on your boat, you must maintain a watch on channel 16 (156.800 MHz) whenever the radio is not being used to communicate. Starting in 2004, if a radio is carried, it must be on and set to channel 16. Whenever your boat is underway.• If you hear a distress call, wait a few minutes to let a shore station or Coast Guard vessel re-spond. If no other station has responded after 5 minutes, you must respond to the distress call. • Do not make false mayday or distress calls as a prank or to test your radio.
