Gps Alarms - Lowrance GlobalMap Sport Installation And Operation Instructions Manual

To send a cold start message to the receiver, move the black box on the
GPS Commands menu to the "Execute GPS Cold Start" menu, then press
the right arrow key. A message appears, asking you if you really want to
do a cold start. Follow the instructions on this message page.
The unit will begin searching for the satellites. It can take as long as 15
minutes for it to lock on to the necessary satellites, but it usually takes
much less time. Remember, when it does, your local time and possibly
date can be wrong. Use the method shown in the initialization section at
the front of this manual to change them, if needed. Once this is done, an
internal clock will keep the correct time, even when the unit is turned off.
The GPS system updates this clock when the unit is locked on to the
satellites.

GPS ALARMS

The GlobalMap Sport™ has three different alarms. An arrival alarm sounds
a warning tone when you cross a preset distance from a waypoint. For
example, if you have the arrival alarm set to .1 mile, then the alarm will
sound when you come within .1 mile of the recalled waypoint. The cross
track error alarm (XTE) sounds a warning when your track drifts too far to
the right or left of the line to the waypoint. For example, if the alarm is set
to .1 mile, then the alarm will sound if you drift .1 of a mile or more to the
right or left of the line to the waypoint. The anchor alarm sounds a warning
when you drift outside of a preset radius. Again, using the .1 mile as an
example, if you're anchored and the boat moves more than .1 of a mile,
the alarm will sound.
Important Alarm Notes:
Anchor Alarm - Since civilian users don't receive the accuracy given to
military users, the anchor alarm may sound even when you're sitting still.
This typically happens when using small (less than .05 mile) anchor alarm
ranges. If you have a DGPS beacon receiver connected to the GlobalMap
Sport™, smaller ranges may be useable.
Arrival Alarm - If you set the arrival alarm's distance to zero (0), and you
run a route (see the routes section), the GlobalMap Sport™ may not show
navigation data to the next waypoint, once you arrive at the first one. If you
use the routes feature, never set the arrival alarm to zero.
To use any of these alarms, first press the MENU key, then select the
"GPS ALARMS" menu. A screen similar to the one shown at the top of the
next page appears. Press the up or down arrow key to move the black box
to the desired alarm, then press the right arrow key to turn it on.
