Owner`s manual

Additionally the number of satellites being tracked and the signal level are shown.
Signal level varies between 1 & 9, 9 being the strongest signal.
7.2-2 SETTINGS
There are four settings related to the Position function. Press SET while in the
POSITION function to access the settings. Use UP or DOWN to scroll.
TURN ON / OFF GPS Receiver Setting
This setting allows you to power the GPS receiver on or off (not the entire Multi-
Navigator), providing you with longer battery life. When using the Multi-Navigator
indoors for pre-planning a trip, or when using the TrueMagnetic Compass over long
distances between waypoints, turn the GPS receiver off.
POSITION FORMAT & MAP DATUM Setting
Select either latitude/longitude or a grid reference system, depending on the reference
system of your map. After choosing the position format you are prompted to select 1 of
over 107 map datums. The default map datum is WGS-84. If you do not know the datum
of the map, use WGS-84. If the map datum is indicated, you should select the same
datum the map is based upon. On USGS Topographic maps, the map datum is indicated
in the lower left-hand corner.
Note! If the wrong datum is selected there is a risk that the position shown on the Multi-
Navigator will not correspond with the actual position on the map. When
translating coordinates to/from the Multi-Navigator the map datum setting must
correspond with the map you are using.
GPS ELEV OFFSET Setting
The GPS elevation from the GPS system is not always accurate. If the GPS ELEV display
(Fig. 13) is deviating from a known altitude, correct the GPS elevation in this setting.

7.3 -- ALTITUDE SIDE FUNCTIONS & SETTINGS
7.3-1 SIDE FUNCTIONS
There is one side function related
to the Altitude function. (Fig. 15)
ALTITUDE Function
The altimeter uses a highly
accurate barometric pressure
based altimeter. Immediately after
calibration, it provides altitude
readings, with accuracies to 3 feet
(1 m). See section 7.3-2 & 7.4-2,
to calibrate the altimeter and
pressure sensor.
Since altimeter calculations are based on the barometric pressure, you will find that
changes in weather will affect the altitude values. Therefore, it is recommended that you
calibrate the altimeter often to achieve the highest possible accuracy.
MIN / MAX Side Function
The minimum and maximum altitudes visited since altitude was last reset are displayed.
