Frequently Asked Questions
| What is the range of the LVR-250? | There is not set range. The range is effected greatly by the installation. VHF radios operate by line of sight. The higher the antenna is installed, the greater the range. |
| Where can I find a VHF antenna for my LVR-250? | Any marine supply store should have them. For this radio, the antenna should have at least 3db of gain. |
| Why can't I get weather on my LVR-250? | The unit may be in an international mode and not searching for available US weather information. Press the H/L and WX buttons simultaneously to cycle between these two modes. |
| What does USCG CFR-46 standard mean? | This is a standard testing method used to define waterproof. The product must withstands 65 gallons (US) of water per minute sprayed through a 1" nozzle from 3.048m (10') for at least 5 min. |
| What channel do I use on the LVR-250? | This depends greatly on what you want to say and who you want to speak with. This is explained in the manual some. A breif desription is also supplied here. |
 | |
| What is an MMSI number? Why do I need an MMSI number? Where do I get an MMSI number for using the LVR-250? | MMSI stands for Maritime Mobile Service Identity. This is like a phone number. You must enter this number of the other party you wish to make a DSC call to. Other parties must also know your MMSI number before the can make a DSC call to you. To register for a unique MMSI number, select this link. |
| What if I make a mistake entering my MMSI number? | Please see your local dealer for assistance. |
| What is the difference between Simplex and Duplex? | The channel in use for communication may be either. If the channel is a Simplex channel, the channel uses only one frequency for transmitting and receiving signals. This makes communication similar to a CB where only one party can talk at a time. Duplex channels actually operate on two different frequencies allow for the radio to transmit and receive at the same time. This is similar to your telephone. |
| Why does the LVR-250 cut me off after 5 minutes of transmitting? | After 5 minutes of constant transmission, the LVR-250 will end transmitting. This is required by the FCC. Simply end a transmission before this time and start your transmission again. |
| Will my radio work with an NMEA 2000 network? | No, it operates on NMEA 0183 (RS-232). |
| Can I use this radio in Canada? | Yes! However, go to this site to learn about the certification required. http://www.cps-ecp.ca/english/VHF_ad.htm |
| What is the FCC ID # for the LVR-250? | EP78TQ LVR-250 |
| What is the flush mount / in-dash kit for the LVR-250? | The FM-10 (Part #113-70) is the in-dash mounting kit for the LVR-250. |
