Vertical Adjustment
In order to satisfy specific application requirements, you may find it necessary
to adjust the vertical position of the sensor mounting pad. You can move the
sensor mounting pad 25.4 mm (1.0") with this procedure.
To adjust the vertical position of the sensor mounting pad, follow the steps
below.
Note:
The sensor mounting pad was pre-aligned and your system was certified
at the factory (see the topic, System Certification in Section 2 for more
information). The following procedure will disrupt the alignment and void the
certification of your Cobra system.
1. Remove the DRS laser sensor, as described in Section 4.
2. Loosen the Locking knob (see Figure 5-3).
3. Twist the Focus knob to raise or lower the sensor mounting pad along the Z
axis slide so that the two M4 socket-head cap screws used to secure the
mounting pad to the system are visible through the access holes in the
mounting pad (see Figure 5-3).
4. Use a 3 mm hex key (Allen) wrench to remove the two M4 socket-head cap
screws used to secure the sensor mounting pad to the Cobra main unit (see
Figure 5-3).
