Receiver or N EA
data Is Turning Off
Entering certain functions, like PLU
functions, or WPT, will turn the receiver off.
To reactivate it, you must press PO , NAV
or VEL. About 2 minutes will elapse before
your position updates again. Unless you
are in continuous operation or on external
power, the receiver will turn itself off after
obtaining a single fix. The NMEA
messages are unavailable in non-
continuous (push-to-fix) operation.
The NAV And
VEL Keys Will Not
Work
The Unit Beeps
When You Press
A Key
1. Navigation requires that you enter a
route (ROUTE key) with a start and
destination. (You can select your present
position as the course start.)
2. If you are not in continuous operation,
only distance, bearing, and XTE are
available to you.
3. Bearings are not displayed when you are
within ±20 meters of your destination.
4. You must be travelling at least 0.2 Knots
to get speed ( OG), ground course (COG)
and steering, speed of advance ( OA),
ETA, TTG, or velocity made good (VMG).
5. Despite the speed of your vehicle,
velocity related data is not available until the
unit has taken three fixes.
You are locked out of the keypad. Be
patient a moment and try again. The unit
was receiving important information from
the satellite and did not want to be
interrupted. To turn the receiver off,
thereby freeing the keypad, simply turn the
unit off.
