12.4.3 Brightness
Here you can set the brightness of the screen.
The brightness settings have a great influence on the power
consumption of your navigation device. To save power in battery
mode, turn down the brightness level.
In addition, you can select whether the screen should automatically be
dimmed when the battery is weak in order to save power.
Confirm your setting by tapping on
.
12.4.4 Navigation sounds
The navigation sound output warns you with a beep when you are approaching a turn-off or when you
deviate from the calculated route.
12.4.5 Calibrate compass
To guarantee precise orientation of the compass, you should recalibrate the compass at regular
intervals. To do this, tap on
Calibrate compass
and follow the instructions on the device.
Note
: You should only ever calibrate the compass outdoors. Make sure when calibrating it that no metallic
objects are located in the vicinity of the device and that no magnetic or electro-magnetic sources of disturbance
(e.g. high-voltage power lines, antennae) are present.
12.4.6 Calibrate barometer
To optimise the accuracy of the height measurement, you should calibrate the barometer at regular
intervals.
You can calibrate the barometer in two ways:
-
Automatic
- The barometer is then calibrated completely automatically.
Note:
To obtain more precise figures, manual calibration is
recommended.
-
Manual by specifying height
- If you know the height of
your current position, enter this and place the device down to
rest on a flat surface for a short time.
-
To standard atmospheric pressure
- Then the
standard atmospheric pressure at sea level is used to
determine the height.
Note:
The barometer should be calibrated after each change of battery.
If there is changeable weather and great height differences, it is
recommended that the barometer be calibrated several times a day.
