longitude. In this example, we have entered .012
degrees south latitude and .068 degrees west longitude
as the PCF offset. That is the difference between the
present position shown on the unit and our position
shown by the chart. In other words, our position shown
on the unit is 0.012 degrees north and 0.068 degrees
east of the position shown on the chart.
After you've entered the desired offset, press the F4
key. This turns the PCF correction factor that you
entered on. To leave this screen, press the CLR key.
This returns the unit to the last used GPS screen. It also
puts your changes into effect.
To turn these changes off, return to this screen and
press the F4 key. Remember, presetting the unit also
erases any PCF offset, thereby turning it off.
