4.4 Changing the Direction of
the Antenna
Adjust the direction of the antenna to be in the
upright position. The direction of antenna is like
Figure 4.2 at the factory setting.
When adjust the electrical connection vertically,
change the direction of the antenna.
To change the installation angle, follow the
procedure below.
1) Loosen the two mounting screws at the bottom
of the antenna by using a 2.5 mm Allen wrench
(see Figure 4.2).
The screws might come off and be lost if
loosened too much; loosen the screws by about
three rotations.
2) Press forward and down 90 degrees by rotating
the axis at the bottom of the antenna.
3) Tighten the two screws to a torque of 1.5 N·m
by using a torque wrench. When doing this, be
careful not leave a gap between the antenna
and housing.
