Exhibit K: User Manual FCC ID: OXZSTDPREVIEW Standard PreView tm Operating Manual/Installation Guide Product Description The Standard PreView tm is a solid-state, pulsed radar object detection system designed to alert vehicle operators to obstacles. The system detects both moving and stationary objects in a pre-defined coverage area and reports the distance of the closest object via visual range indicators and an audible signal to a vehicle operator. The PreView tm system is designed to supplement other safety practices and is not to be the sole method of collision avoidance. The Standard PreView tm consists of three major components: an environmentally sealed sensor, an operator display mounted in the cab of the vehicle, and a recommended external back up warning alarm. The Standard PreView tm system does not require cleaning and is not effected by harsh weather conditions, including temperature extremes, rain, sleet, snow, or fog. Sensor/Antenna Description The antenna assembly transmits and receives low power 5.8GHz radar signals. It then processes the returned signals to determine if an object has reflected any energy back to the sensor and reports this to the operator display. The sensor is designed to process and report detections within of a second allowing the vehicle operator to quickly respond to any object within the detection zone. All connections to a vehicle are accomplished at the sensor. Power is obtained from the vehicle reverse lights and a relay contact is provided for operating a back up alarm. The connection to the display unit is through a watertight connector eliminating any potential problems with pin corrosion. Power to the operator display is provided through the sensor interface to the display. The sensor RF output is pulse modulated so that it will not interfere with similar devices.

Maple Grove, Boise, ID 83704 (800) 453-1141 Copyright 2002 Page 1 of 10 370-871-1B Operator Display Description The operator display provides the vehicle operator with both visual and audible indications of a detected object. Range to the detected object is provided with five LEDs in a relative format with each LED representing approximately 1/5th of the total range. The display unit also contains a buzzer to provide an audible alert. The buzzer audible rate will increase as an object becomes closer, providing the operator with another cue that an object is being detected. The operator display continuously monitors communication from the PreView tm sensor and in the event of a system failure or malfunction will notify the operator with a fault indication. See Operator Display Error Indications below for further detail on fault messages. A buzzer volume control switch is provided on the front panel of the display allowing the vehicle operator the ability to adjust the buzzer volume to three different levels. Buzzer Volume Control Button Range Indications 5 Zones Green Power On Item Green Power ON Range Indications Buzzer Volume Control Switch Description Illuminates continuously after power is applied to the system. The power ON LED will blink quickly if a system malfunction occurs. Illuminate to give operator a relative distance measurement to the closet detected object. LEDs operate from the right to the left, with the closer an object the more LEDs illuminated. Also used for error codes. Sounds audible tones to alert operator of obstacles. The buzzer tone rate will increase as the vehicle gets closer to an object. This momentary push button switch allows three different buzzer volume levels to be selected as well as providing the capability of turning off the buzzer. Table 1. Operator Display Description Object Detection Capability The Standard PreView tm system can detect most objects within the detection zone. However, there are some instances where objects can go undetected. Obstacle size, shape, and composition are all factors determining if, when and where an object is detected. The PreView tm system operates by transmitting a pulse of very low power electromagnetic energy. Any Preco Electronics, Inc. 415 N. Maple Grove, Boise, ID 83704 (800) 453-1141 Copyright 2002 Page 2 of 10 370-871-1B energy that strikes an object reflects a certain amount of this energy back to the PreView tm sensor. This returned energy is measured to determine an objects distance. The amount of energy returned is based on a few factors:
Size a larger object usually reflects more energy than a smaller object. Distance the farther away an object is, the less energy is returned. Composition a metal object reflects more energy than a non-metallic object. A metallic object at the edge of the zone will be detected, where a wood object may not. Scattering a solid object reflects more energy that a non-solid object such as wood, gravel, bushes, etc. Angle an object perpendicular to the sensor will reflect more energy than an object at an angle. See below for a detailed explanation.

Check the contents of the shipping package and verify the following items are included:
Antenna Sensor (1) Display Unit (1) Interconnect Cable (1) User Manual/Operating Instructions Sensor Mounting Hardware Display Mounting Hardware
(3) 1 1/4 x 10-24 Bolts
(3) Hex Locking Nuts
(3) Flat Washers Mounting Bracket
(2) #4-40 Lock Nuts Sensor/Antenna Location The PreView tm sensor mounting location is key to proper system operation. Ideally the sensor should be mounted on the rear center of the vehicle at roughly 36 (1M) +/- 12 (0.3M) above the ground. The sensor should be perpendicular to the ground. Select a location that will provide some protection from impact and debris while allowing an unobstructed view of the target hazard area. IImmppoorrttaanntt!!
Before the PreView tm system is permanently installed to the vehicle verify that the selected sensor mounting location provides a clear detection zone. This can be done by applying power to the system with the sensor in the proposed location and verifying that nothing is being detected. Sensor/Antenna Mounting 1. Select the appropriate sensor mounting location. 2. The sensor must be mounted with the cable exit either on the bottom (preferred) or top. 3. Using the sensors mounting holes as a template, scribe position marks through the holes. Drill 9/32 (7mm) holes centered at the marks. (CHECK THESE DIMENSIONS) 4. Secure the sensor to the vehicle with the three supplied 10-24 UNC bolts, washers and nuts or equivalent. Apply a maximum torque of xx inch pounds when securing the sensor. Sensor Power Connection Locate the vehicles reverse light power wire and connect to the red wire on the sensor harness using 18AWG wire. Connect the black wire of the sensor harness to vehicle ground. Preco Electronics, Inc. 415 N. Maple Grove, Boise, ID 83704 (800) 453-1141 Copyright 2002 Page 5 of 10 370-871-1B Back Up Alarm Electrical Connection The PreView tm sensor provides a form C (normally open) relay contact that can be used to activate an external back up alarm. The PreView tm system activates this relay output whenever an object is detected. The orange and white wires on the sensor harness are the interface to this relay contact. NNOOTTEE::
The PreView tm sensor does not provide power for a back up alarm. Display Unit Installation The display unit should be mounted where the vehicle operator can easily view it while backing. The ideal location for this is on the dash by either windshield pillar. This will allow the operator view of the display while also looking out one of the side mirrors. The display unit harness should be taken into consideration when selecting a mounting location for the display. Since the connection between the display and sensor harness is not watertight, it should be routed in such a manner so it is not exposed to the outside environment. The PreView tm display unit comes equipped with a mounting bracket and hardware. If desired, the display unit can be mounted to the display bracket with the supplied hardware. This bracket can then be mounted in the vehicle cab as desired. Cable Installation The interconnect cable between the sensor and display is 25 feet (7.6M) in length. If the distance between the sensor and display is greater than 25 feet, contact Preco for additional cable extensions. Routing of the cable should start at the sensor end since the display end comes equipped with a grommet for sealing the entry point into the cab. Allow for a small service loop in the cable at the sensor and secure the cable every few feet (~1M) with tie wraps. When ready to enter the cab, drill a 9/16 (14mm) hole and feed the display connector through. Once the connector is through, the grommet can then be pulled into the hole until snug. The remaining length of cable is then routed to the display unit and the connectors are fitted together with the connector latch engaged. Care should be taken to not route the cable next to heat sources such as engines and exhausts and areas that may see abrasion or rock damage. Initial System Power Up and Test Once the sensor and display are installed, wired, and connected, power should be applied to verify correct system operation. Upon power up, the display will go through its self-test by illuminating all LEDs and sounding the buzzer. When the system is operating correctly in an open field with no obstructions, the green power LED will be the only light illuminated. If all the detection (yellow) LEDs are lit, check for any obstruction which may be detected by the sensor. If possible move the sensor so it is not detecting the object(s). If it is not possible to relocate the sensor, then consult the factory. It may be possible to ignore the obstruction. Preco Electronics, Inc. 415 N. Maple Grove, Boise, ID 83704 (800) 453-1141 Copyright 2002 Page 6 of 10 370-871-1B If for some reason the system is malfunctioning, all of the yellow LEDs will be flashing and the buzzer will be sounding. Refer to the Error Indications and Troubleshooting sections below to determine the error and solution. Once the system has been installed, the detection zone should be tested. Testing is accomplished by using two individuals. One individual is engages the parking brake and places the vehicle in reverse. The other individual then walks through the detection zone noting where the display buzzer or the back up alarm activates. By moving about the rear of the vehicle and noting when the display or back up alarm activate, an accurate detection zone can be mapped. Preco Electronics, Inc. 415 N. Maple Grove, Boise, ID 83704 (800) 453-1141 Copyright 2002 Page 7 of 10 370-871-1B COMMON INSTALLATION PROBLEMS AND TROUBLESHOOTING Display power ON green LED is not illuminated. Verify that keyed DC power is applied to the sensor (+12V to red wire and ground to black wire). Verify that the cable between the sensor and display is connected. Display continuously flashes. Check connection between display and sensor. If sensor had just been connected to the service tool, cycle power to sensor after connecting to display. If the system has multiple sensors, verify that Y interconnect cable is correctly installed with the connector with the gray molding connecting to the sensor that is farthest away from the display. All the display LEDs are illuminated when sensor is mounted. Verify the sensor is pointing outward from the vehicle in an open area with no obstructions. This may require removing the mounting screws and lifting the sensor out away from the rear of the vehicle. If the display LEDs are not active when moved away from the vehicle, but are active when mounted, then either a special bracket must be used to move the sensor away from the obstruction or a calibration must be performed. See the service tool user manual for further details on how to perform a calibration. Back up alarm does not operate when connected to the PreView tm sensor. Verify that the sensor reverse input (blue wire) is connected to the vehicles reverse indication. Verify that the sensors orange wire is connected to the back up alarm positive (+) input and the white wire is connected to the back up alarm negative (-) input. Disconnect all other back up alarm connections to the vehicle. Sensor is detecting the ground, indicated by a few of the display LEDs being lit. In an open field, either move the sensor up higher or slightly angle the sensor upward 2 to 5 degrees. The minimum recommended mounting height is 30 inches. Contact Preco for an angle bracket if one is required. Cable between display and sensor is too short. Contact Preco for an extension cable. This cable is placed between the sensor and display cable and comes in 5, 10, 15 and 25 increments. Detection pattern seems wider when a vehicle is detected rather than a person. This is normal since any vehicle presents a larger radar cross section than a person. If desired, modify the configuration by either shortening the range or going to a narrower pattern.

The units on operating vehicles must be tested each day prior to the vehicle's operation. Results of this test must be recorded in the maintenance log. 3. People operating this equipment MUST check for proper operation at the beginning of every shift or safety inspection period. 4. People's lives depend on the proper installation of this product in conformance with these instructions. It is necessary to read, understand and follow all instructions shipped with the product. 5. Failure to follow all safety precautions and instructions may result in property damage, serious injury, or death. 6. The PreView tm Object Detection System is intended for commercial use. Proper installation of a back-up aid requires a good understanding of truck electrical systems and procedures, along with proficiency in the installation. 7. Store these instructions in a safe place and refer to them when maintaining and/or reinstalling the product. Testing and Maintenance NOTE: A walk around test shall be performed every day to verify proper function of the system and to familiarize the operator with the zone of detection. More frequent inspections should be performed when:
This test should be performed with two people, one who remains in the cab (the operator), and one who walks through the sensor field to the rear of the vehicle (the assistant). 1. Clean the black sensor surface of any accumulation of dirt, mud, snow, ice, or debris. 2. Visually inspect the attached wiring and cable and verify that they are properly secured, not chafing or dangling free The vehicle is operating in a particularly dirty or harsh environment. The operator has reason to suspect the system has been damaged. where they could become snagged and damaged. Inspect the Radar Sensor and Operator Display Module and verify that they are securely attached to the vehicle. 3. Start the vehicle, set the park brakes, and place the vehicle in reverse. 4. Verify the green POWER light is illuminated on the in-cab display. 5. The area to the rear of the vehicle should be clear of obstacles for a distance of 8 meters. If the display shows any indicator other than the green light then there are objects to the rear of the vehicle that will interfere with the test. Move the vehicle to a clear area and proceed. 6. The assistant should move to the rear of the vehicle and to the side so that he is in sight of the operator's mirrors. He should begin meter (20) to the rear of the rearmost part of the vehicle. As the assistant walks towards the centerline of the vehicle parallel to the rear, the external backup alarm will activate, signifying the sensor has detected him. Upon hearing the backup alarm the operator should verify all the display LEDs are lit and the audible alarm is quickly pulsing. Note: If an external backup alarm is not connected, the operator will notice a detection only by the display LEDs and buzzer operation and communicate the detection or lack of detection to the assistant as the assistant moves through the area to the rear of the vehicle. 7. The assistant should continue walking through the area at the rear of the vehicle noting the area that detection occurs. 8. Now walk from the center of the rear of the vehicle straight back, away from the vehicle. When the alarm quits sounding 9. Move halfway back and remain still for a few seconds, the alarm should continue to sound, demonstrating the systems 10. The assistant should walk the complete rear of the vehicle noting the detection edges of the entire coverage area. 11. After the test the assistant needs to communicate to the operator the details on where detection started and stopped to the detection limit has been reached. ability to detect a still object. the rear of the vehicle.
