4.5.4 SETTINGS/ALTERNATIVES IN THE TIME FUNCTION
4.5.4.1 12/24 HOUR TIME FORMAT
Select in which format you would like the time to be presented. Available options are 12 and 24 hours.
4.5.4.2 SET TIMEZONE
Here you set your local timezone (in 30 min intervals) compared to UniversalTimeCoordinated (UTC) See chapter 3.
Enter a positive value for timezones located eastbound and vice versa for westbound timezones. Note that the
Multi-NavigatorTM will find the UTC time by itself, thanks to the data received from the satellites.
4.5.4.3 MORE SETTINGS
See 4.5.1
4.5.5 SETTINGS/ALTERNATIVES IN THE BARO FUNCTION
4.5.5.1 BARO HISTORY (FIG. 039)
Here you can read the pressure history over the last 36 hours. The values shown, indicate the absolute pressures
recorded over the previous 36 hours and the change compared to the present barometric pressure. Leave the
function by pressing NO-button
4.5.5.2 BARO ALT CORR (FIG. 040)
This function is good to use if, for example, you are staying/living at high altitude and want to read the air pressure
at sea level. Enter the altitude you are at and the barometric readings will be shown as if you were at sea level. If
you do not enter a reference altitude (0 metres) you will have the absolute air pressure shown in the display. It can
be good to know that 8 metres in altitude means a pressure change of one (1) hPa/mbar and that normal air
pressure at sea level is 1013 hPa/mbar.

4.5.6 SETTINGS/ALTERNATIVES IN THE ALTITUDE FUNCTION
4.5.6.1 SET REF ALT
This is a very good function if you want to keep track of your altitude compared to, for example, the altitude at which
you started your trip. In this function you set your current altitude as the reference altitude. This means that the
display will show how many metres (or feet) you have ”gained” or ”lost” compared to the reference altitude. When
a reference altitude is set, the altitude is shown in the display with a small triangle side.
4.5.6.2 EDIT REF ALT
Here you can set a reference altitude at a different position from the one you are at. Also, you can set the reference
altitude to zero if you want true altitude to be read in the altitude function.
4.5.6.3 CALIB ALTITUDE (FIG. 041)
Calibration of the altimeter. When YES is selected you use UP/DOWN to enter your current altitude above sea-
level. In the bottom row you see a pressure value. This is the reduced pressure value at sea level (QNH-
QuasiNonHydrostatic). This will change as you change the altitude value. If you know the local QNH-pressure (from
a weather forecast, airport etc) you press UP/DOWN until that is read in the display - the instrument will then be
automatically correctly calibrated. If you have not calibrated your altimeter for a long period of time and you are
unsure of the changes in air-pressure since the last time, it can be a good idea (and quite accurate) to check the GPS
ELEVATION (see 4.4.1.1) and use that as your calibration altitude.
Note! We recommend you calibrate the altimeter frequently in order to achieve accurate readings.
