Continue entering your altitude, present time and date the same way you
entered your present position. If you make a mistake entering a number,
use the arrow keys to move back to the number that you wish to change,
then enter the correct number.
When all of the numbers on the screen are correct, press the “ENT” key.
This sends the values you entered to the GPS module which should
shorten the time required for it to find the satellites and return your present
position. If you don’t move a long distance (over 100 miles) with the unit
turned off, then you probably won’t need to do the initialization again, since
it stores all of the last known position settings in memory each time it’s
turned off. An internal clock keeps track of the time, even when the unit is
turned off, so that it will be correct the next time it’s used.
Once the GPS module finds the satellites and displays the correct latitude/
longitude for your position, then the GlobalMap 2000 is ready for use.
COLD START
When the GlobalMap 2000 is turned on for the first time “out of the box”,
it automatically sends a “cold start” message to the Lowrance GPS
module. You can also send a cold start message to the receiver. 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. For example, given it east
longitude instead of west. Or if you’ve moved a long distance with the unit
turned off.
To send a cold start message to
the receiver, first press the
MENU key. Now press the key
next to the “GPS/DGPS Setup”
label. The screen at right ap-
pears. Finally, press the key
next to the “Cold Start GPS
Receiver” label. The unit will
begin a cold start technique to
find the available satellites. It
should lock on to them in less
than 15 minutes. Remember,
when it does, your local time
and possibly date display will probably be wrong. Use the method shown
above to set the time and date. 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.
