1.4 Wording for User Manual

0 265 K60 059

The user manual shall contain the following statements

This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry Canada.

Operation is subject to the following two conditions:

(1) this device my not cause harmful interference, and (2) this device must accept any interference received, including interference that may

cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

• Consult the dealer or an experienced radio/TV technician for help.

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body.

Warning: Changes or modifications made to this equipment not expressly approved by ROBERT BOSCH GmbH may void the FCC authorization to operate this equipment.

3.1 Installation instructions for the ACC2 - SCU

The ACC SCU is installed in the frontal area of the vehicle. The sensor lens points in the vehicle driving direction, the connector either down to the road or up. The outline dimensions of the sensor are shown in the following drawing:

Ambience Conditions and Mechanics

Ideally the sensor is to be integrated into the front-end without a cover in front of its lens. If the sensor is to be installed behind a cover or a radome, special care must be taken in

selecting the cover-material, cover shape (or design) and position of the cover relatively to the sensor. Water droplets and snow sticking onto the cover surface might cause additional attenuation that leads to a restricted performance or availability of ACC. For the uncovered build-in configuration the lens design of the ACC-SCU is chosen to minimise these effects. Water droplets can be blown off by the driving wind and sticking snow can be heated off by the integrated lens heating.

The following table lists the basic demands to the integration of the sensor into a front-end

of the car: Installation height above ground (roadway) Horizontal offset relative to the vehicle longitudinal axis

Horizontal angle relative to the vehicle longitudinal axis

Vertical tilt relative to the vehicle longitudinal axis

1 1

(dependent on pitch when car is fully loaded or while braking) Clearance of parts (out of metal or even plastic) in front of the

sensor can be described by a cone directly in front of the lens with the following angles

horizontal

vertical The cone that represents the radar beam in shown in figure 1 Clearance to other vehicle parts:

(sensor-movement during adjustment: ± 3° vertical and horizontal

and additional space for the bracket behind the SCU is considered)

in lateral direction

in front of the lens

behind the sensor (space for clip and bracket) Permissible attenuation caused by cover (bumper, radome) in front of the lens ; two-way (radar) loss The constraints for the cover are:

- homogeneous material has to be favourized

- non perpendicular orientated relatively to sensor radar axis

- favoured materials : see following material list

The material in front of the radar should not degrade the antenna parameters

• Beamwidth error

• Sidelobe change

• Peak boresight error

In case of radome heating the orientation of wire structures has to be checked Wire diameter is limited to max. 0.25mm
