Operating Your Radio
GPS Menu
All VHF Marine radios SHOULD / NEED to have a GPS receiver connected and operating
to effectively use the DSC (Digital Selective Calling) features built-in to the radios.
In an Emergency you want the rescue authorities and surrounding vessels to know
where you are and to be able to quickly assist you in your time of need. Your MR F77
radio has a GPS receiver built right in!
This menu allows you to select the internal GPS receiver (already selected by default),
select and external GPS receiver, select the coordinate system which is basically the
accuracy (the most accurate setting is already selected by default), Select the Satellite
Based Augmentation System to be enabled or turned off (some areas on Earth need
this turned off for greater accuracy)(defaulted On), and allows you to test the GPS
receiver (will test either the internal or an external GPS receiver) to be sure that you
are receiving good satellite information and check the GPS signal strength.
To Select the Internal or an External GPS Receiver:
1. Enter the Settings menu and scroll to
GPS MENU
with the Up/Down soft keys or the Up/Down channel
buttons.
2. Highlight the INT/EXT GPS option in the menu.
3. Press the ENTR key and observe the current setting.
4. Use the Up/Down soft keys or the UP/Down channel
buttons to change the setting to use the internal GPS or
turn off the internal GPS to use and external GPS.
5. Press the ENTR soft key to select the setting. Or press the
EXIT soft key to
EXIT without making changes to the
GPS setting.
6. The radio will return to the GPS menu. The radio will
remember the saved GPS setting, when powering off the
radio, or disconnecting power to the radio.
