FAQ

How do I remove the current MMSI number from my newer radio?

For radios produced in 2018 and newer we can do this remotely! We would need you to email [email protected] with the following information: Name, Model Number, Serial Number, Current MMSI, and the Request Code. The radios Request Code you will find the radios Reset Menu under the option MMSI. All are needed to provide you a reset password via email. Typically, we can provide you a reset password in about 2 business days.

How can I check to see if my radio is receiving correctly? I don’t seem to hear anyone talking.

Try switching the radio over to the Weather channel mode. When you are in this mode the USA will disappear and be replaced by WX on your screen. Make sure you check all 10 weather channels to find your local one. If you receive weather loud and clear, this is a good sign your radios receiver is working as the radio only has one receiver. You may be out of range of other boaters, or you may be listening on channels no one is actively using at the time.

Why can others not hear me when I transmit?

There are several reasons this can happen which are not a fault of the radio. Make sure you test with another person who is aware you will test your radio with theirs. Check that both radios are on a common non-emergency channel such as channel 68. Speak clearly directly into the microphone hole opening with your mouth no more than 2 inches away. Try setting your radio to Hi transmit power.

I am transmitting in an area with lots of boats and no one responds to me. Why is this happening?

Although there are other boaters near you, 1) they must have their radio turned on, 2) they must be on the same channel, 3) be able and willing to respond to your call.

When I press the talk button (PTT) my radio’s display will shut off and restart. Why does this happen?

The radio will shut down to protect itself. This will happen when the radio is unable to get sufficient “energy” from the power source. - On a vehicle installation you want to check the voltage at the radios rear DC connector. It should be about 13.8 VDC. If this voltage at the radio drops below 11 VDC, the radio will shut down. - Consider reducing the DC cables from the radio as direct to the battery as possible. - Try to use a higher gauge (thicker) cable if the DC must travel long distances.

The radio is asking me to enter my MMSI number. Where do I get this number?

The MMSI numbers are a number you will need to register for through one of the registration agencies. For a U.S. registered MMSI number you can reach out to Boat US or United States Power Squadrons. For an MMSI number for international use you will have to register through the FCC.
