To turn the simulator on, press the up or down arrow keys until the "GPS
Simulator" menu is surrounded by the black box. Now press the right ar-
row key. Press the EXIT key to erase this menu.
Note: Your plot trail will be erased when you turn the simulator on or off.

GPS Update Rate

Changing the update rate conserves battery power and lengthens the
battery life. The update rate is the length of time it takes the receiver to
send data to the display. In other words, normally the receiver sends posi-
tion data out once every second. You can reduce that time to once every
five seconds. However, slowing the update rate also makes it harder to
use this product at slow speeds, such as hiking or sailing. The faster the
update rate, the better the unit can respond to changes in direction or
speed.
If you wish to change the update rate, simply move the black box to the
"GPS Update Rate (SEC)" menu, then press the left or right arrow key to
move the black box over the desired rate: 1, 2, 3, 4, or 5 seconds. Press
the EXIT key to activate your selection.
Execute GPS Self Test
If you suspect a problem with the GPS receiver,
or just wish to test it, move the black box on
the GPS Commands menu to the "Execute
GPS Self Test" label, then press the right ar-
row key. A screen similar to the one at right
appears after several seconds. Messages at
the bottom of the display will tell you if the unit
passed the self-test, or failed. If the unit fails
the self-test, contact the Lowrance customer
service department.

Execute GPS Cold Start

When the GlobalMap Sport™ is turned on for the first time "out of the
box", it automatically sends a "cold-start" message to the GPS receiver.
You can also send a cold start message to the receiver at any time.
If the unit can't lock on to the satellites using the data you've given it, or if
it has trouble finding the satellites, perhaps it is using the wrong data. This
can happen if you've entered the wrong data by accident when initializing
the receiver. For example, if you entered east longitude instead of west.
Or if you've moved a long distance with the unit turned off.
