CHAPTERS
BASIC OPERATION
3.1 POWER ON
After you turn your GPS 65 on. It will conduct a series of self tests and
display the following notice:
Welcome to GHRnXN's

CftRHIM OORF
Following completion of the tests, the Satellite Bar Graph Page (see
Section 3.2) will be displayed, and the GPS 65 will begin acquiring
satellites.
After a position is found (and if no keys have been pressed), the Position
Page (see Section 3.3) will be displayed, and the unit is ready for normal
operation.
When four or more satellites with good geometry are available, the GPS
65 will automatically operate in the 3D mode in which latitude,
longitude, and altitude are computed. If only three satellites are
available, the unit will operate in 2D mode in which only latitude and
longitude are computed. When operating in the 2D mode, the emit will
use the last computed altitude or your last entered altitude. (Section 3.3
describes how you may enter the altitude.)
Your GPS 65 will automatically update satellite orbital data as it
operates. If you have not operated your unit for a period of six months
or longer, it vrill take approximately 15 minutes to search Uie sky and
collect new orbital data. You will be informed when your unit is
searchii^ the sliy with the message “Searching (he Sky." Once satellite
orbital data is collected, it will be stored in memory. The memory is
maintained by an internal battery, therefore the data will not be lost
when you turn your GPS 65 off.
