ENGLISH
Once this is carried out, the learning data is
cleared. When you exit from the navigation
setting menu, the System will perform
calibration internally again.
• If the guidance has been activated, you cannot
use this function.
UNIT ANGLE
You can register the unit angle manually.
• Installation angle of the main unit is
automatically required to be preset when you
use the Navigation System for the first time
after installation or when you delete run time.
• If the guidance has been activated, you cannot
use this function.
Set one of the angles measured by the supplied
gauge:
• UNIT ANGLE 1: Select when the
installation angle is within the range of –5.0
to 17.0˚.
• UNIT ANGLE 2: Select when the
installation angle is within the range of 17.0
to 23.0˚
• UNIT ANGLE 3: Select when the
installation angle is within the range of 23.0
to 28.0˚.
• UNIT ANGLE 4: Select when the
installation angle is within the range of 28.0
to 32.0˚. *
* It is not recommended to install the main unit
at an angle of more than 30˚; otherwise, the
malfunction may result.
TEST
You can confirm the following of the current
status:
• Direction/Learning level*
1
• Velocity/PPS (Pulse Per Second)
• Gyro sensor/Unit angle
• Latitude/Number of GPS satellite received*
2
• Longitude
* 1 Indicates the learning data level. The higher
the number is (the highest number is “4”),
the more accurate the learning data is.
(Learning data is the one the System
accumulates for accurate navigation—such
as velocity, Gyro output level with respect to
car’s movement.)
* 2 If “NG” is shown instead, the GPS antenna
is not connected, or short-circuited.
VERSION CHECK
You can confirm the software version of the
digital maps (DB).
DELETE RUNTIME
Reset the run time in the following cases:
• When you reinstall the unit to another car.
• When you replace or rotate the tires.
