is switched off and you will instantly have a back-lit compass to check your direction. Release the COMPASS-button
and the Multi-Navigator
TM
is switched off again.
When the batteries are empty and you take them out of the Multi-Navigator
TM
you have 2 hours to put in new ones
in order not to lose the barometric history and the latest calculated GPS position as well as the time. Note! You will
not lose any stored waypoints if the batteries are out for more than 2 hours.
As you see, there are lots of possibilities and it is virtually only your imagination that sets the limits.
6 Maps and their reference systems
6.1 Lat/Long (FIG. 045)
The most common way to describe a position on Earth is to use the latitude/longitude system. The base in the Lat/
Long system is the centre of Earth. Longitudes run from North to South (from the North Pole to the South pole) and
Latitudes runs in an East-West direction. The Longitude describes the position in degrees East or West of the 0-
degree meridian. The maximum value of Longitude East or West is 180 degrees. Latitude describes the position in
degrees North or South of the Equator. The maximum value of a Latitude North or South is 90 degrees. Lat/Long
systems are found on most topographical maps all over the world. Lat/long can be presented either in degrees,
minutes and hundreds of minutes (DDDMMMMM) or in degrees, minutes and seconds (DDDMMSSS)..
6.2 UTM system (FIG. 046)
Another common way to present a position on a map is by using grid-systems. The most frequently used grid-
system worldwide is the UTM-system. (Universal Transverse Mercator) This is a global system where the Earth has
been divided in 6-degree sectors (zones) and within every zone a (UTM) grid system has been created. The zones
are numbered from 01 to 60 and the 0-degree meridian is between zone 30 and 31. Within every zone there are co-
ordinates (Northing and Eastings that describe the position. This means that you always have to specify which zone
you are in when for example entering a waypoint since there are 60 places on Earth with the same UTM Easting
and Northing co-ordinates. Please see chapter 5.1.1 for further reference.
6.3 Other grid systems
There are different grid-systems available in different countries/areas. Among others you will find the UK (Ordnance
Survey) grid, Finnish grid, Taiwan grid, New Zealand grid, Swiss grid, MGRS and Netherlands grid.
7 Maintenance, FAQs and fault finding
7.1 Maintenance *
o clean the instrument, use only mild soap solution and rinse with water. * Do not use detergents or high pressure
washing equipment. * If the Multi-Navigator
TM
is to be used on an ATV, snowmobile etc - check that the spark plugs
and ignition cables are shielded to prevent them for interfere with the Multi-NavigatorTM electronics.
7.2 Fault finding
7.2.1 The Multi-Navigator
TM
does not start at all
Check that you have inserted ”fresh” batteries correctly, by unscrewing the locking screw at the bottom of the
Multi-Navigator
TM
and checking the orientation of the battery polarities.
7.2.2 The GPS receiver can not calculate its position
Are you indoors? If so - go out on a fairly open spot and try again. If you are outdoors - check that you have a clear
view of the sky - this is especially important when starting the unit for the first time or a long period of time after it
was last GPS-navigating.
