The radio supports RMC, GLL, GNS, GGA and ZDA sentences. When these sentences are received, the radio displays latitude/
longitude, date, time, course, and speed. If any sentence except an RMC or GLL sentence is received, the radio uses the information
based on the following priority order.
• Status:RMC > GLL > GNS > GGA
• Latitude/Longitude:RMC > GLL > GNS > GGA
• UTC Time: RMC > GLL > GNS > GGA > ZDA
• Date: RMC > ZDA
• Speed / Course:RMC
NOTE 1: If the radio receives only a GLL sentence, the radio does not display the current speed, course, and date.
NOTE 2: If the radio receives both RMC and GLL sentences, the radio uses only the RMC sentence.
NOTE 3: Status data is used to check whether the GPS data is valid or invalid.
NMEA Output
When the radio receives a DSC call (Distress, Position Reply, or Position Send), it outputs a DSC/DSE sentence from the NMEA
output port.
NOTE: When the radio receives a distress call, it outputs a sentence in the following format:
•
$CDDSC,12,3081234000,,07,00,0354013946,0657,,,S,E*6D
•
$CDDSE,1,1,A,3081234000,00,60875646*13
REGULATIONS AND SAFETY WARNINGS
Maritime Radio Services Operation
WARNING!
This transmitter will operate on channels/frequencies that have restricted use in the United States. The channel assignments
include frequencies assigned for exclusive use of the U.S. Coast Guard, use in Canada, and use in international waters. Operation on these
frequencies without proper authorization is strictly forbidden. See the channel tables beginning on page 29 for a list of available channels and
their uses. If you are still not certain which channels to use, see the FCC maritime radio page at the FCC website (http:// wireless.fcc.gov/marine/)
or contact the FCC Call Center at 1-888-CALLFCC. For individuals requiring a license, such as commercial users, you should obtain a license
application from your nearest FCC field office (for US users) or Industry Canada (for Canadian users).
Basic Radio Guidelines
You should familiarize yourself with the rules on marine radios and be aware of which rules apply to your boat. Complete guidelines for all ship and
marine radio types can be found at the US Coast Guard website under the topic Radio Info for Boaters (the direct link is
http://www.navcen.uscg.
gov/marcomms/boater.htm
). 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. Effective from 2004, if a radio is carried, it must be turned on and set to channel 16 whenever your vessel is underway.
• If you hear a distress call, wait a few minutes to let a shore station or Coast Guard vessel respond. If no other station has
responded after 5 minutes, you must respond to the distress call.
