Garmin GPSMAP 295 - Manual (Page 13)

Basic Operation
3
To turn the GPSMAP 295 on, press and hold the RED POWER KEY.
A Welcome Page will appear while the unit conducts a self test. Once testing is complete, the
Welcome Page is replaced by a Database Page. The Database Page shows the effective dates for the
Jeppesen database and a warning that the GPSMAP 295 is for VFR use only.
Press ENTER to acknowledge the Database Page.
The Satellite Status Page will appear as the GPSMAP 295 looks for available satellites. The
GPSMAP 295 continuously collects and stores “almanac” data when it receives a satellite(s). Almanac
data tells the GPS receiver where to look for each GPS satellite in the constellation. Each time you turn
the GPSMAP 295 on, it will use this almanac data—along with last known position, date and time—to
determine which satellites should be in view.
A minimum of three satellites is required for a two-dimensional position fix (2D Navigation),
whereas at least four satellites are necessary for a three-dimensional position (3D Navigation). A three-
dimensional position includes latitude, longitude and altitude. Additional satellites are occasionally
needed to triangulate your position and, even if not needed to determine a position, additional satellites
will also improve position accuracy.
During normal use, expect a position fix in 30-45 seconds. Once a sufficient number of satellites are
received, the GPSMAP 295 will automatically transition from the Satellite Status Page to the Map Page.
Your position will appear on the map and, once you select a destination, the GPSMAP 295 will be ready
to help you navigate.
If you press any keys while the unit is acquiring satellites, the automatic sequencing
from Satellite Status Page to Map Page will not occur.
At the end of the day, when you’re finished using the GPSMAP 295, the same RED POWER KEY
that you use to turn the unit on also turns the unit off.
To turn the GPSMAP 295 off, press and hold the RED POWER KEY.
Turning the Unit On / Off
After the initial Welcome Page, the Database Page appears to
indicate the database coverage area and effective dates. A
warning also reminds you that electronic charts should always
be double-checked for accuracy and are for VFR use only.
An additional page will appear in the start up sequence
when an optional MetroGuide cartridge is installed.
MetroGuide cartridges provide additional map detail and
“points of interest” data for automotive use.
