Maple Grove, Boise, ID 83704 (800) 453-1141 Copyright 2006 Page 1 of 12 370-xxx-1A WideBand PreView tm Operating Manual/Installation Guide Product Description The WideBand 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 WideBand PreView tm system is designed to supplement other safety practices and is not to be the sole method of collision avoidance. The WideBand 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 WideBand PreView tm system does not require cleaning and is not effected by harsh weather conditions, including temperature extremes, rain, sleet, snow, or fog. The WideBand PreView tm system comes in three different models: WPV 2020 Twenty (20) foot detection range WPV 2015 Fifteen (15) foot detection range WPV 2010 Ten (10) foot detection range Sensor/Antenna Description The antenna assembly transmits and receives low power 6.5GHz radar signals. It then processes the returned signals to determine if an object has reflected any energy back to the Preco Electronics, Inc. 415 N. Maple Grove, Boise, ID 83704 (800) 453-1141 Copyright 2006 Page 2 of 12 370-xxx-1A sensor and reports this to the operator display. The sensor is designed to process and report detections within ½ 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. 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 LED’s. Each LED represents 1/5 th of the total range. Example: For the WB2015, each LED represents 3 feet. The display unit also contains a buzzer to provide an audible alert that will increase in rate 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 WideBand PreView tm sensor and in the event of a system failure or malfunction will notify the operator with a fault indication 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 four different levels.

The power will change from green to red if a system malfunction occurs. Range Indications Illuminate to give operator a relative distance measurement to the closet detected object. LED’s operate from the left to the right, with the closer an object the more LED’s illuminated. Buzzer Sounds audible tones to alert operator of obstacles. The buzzer tone rate will increase as the vehicle gets closer to an object. Volume Control Switch This momentary push button switch allows four different buzzer volume levels to be. Table 1. Operator Display Description Object Detection Capability The WideBand 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 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 object’s 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. Preco Electronics, Inc. 415 N. Maple Grove, Boise, ID 83704 (800) 453-1141 Copyright 2006 Page 4 of 12 370-xxx-1A Figure 1.

MPE Estimate Antenna Type Transmit Frequency Maximum radiated EIRP Antenna Gain Minimum Antenna Cable Loss Power Density @ 20 cm General Population Exposure Limit from 1.1310 (GHz)(mW)(dBi)(dB) (mW/cm 2 )(mW/cm 2 ) Patch Array6.324401100.4861 FCC ID: OXZWBPV2006 Compliance with 47 CFR 15.247(i) “Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission's guidelines. See § 1.1307(b)(1) of this chapter.” The EUT is a wideband transceiver that operates in the 5925-7250MHz band. The EUT will only be used on vehicles to help identify objects around the vehicles. The EUT will only be used with a separation distance of 20 centimeters or greater between the antenna and the body of the user or nearby persons and can therefore be considered a mobile transmitter per 47 CFR 2.1091(b). The EUT has a single integral antenna, with a gain of 11dBi. The maximum equivalent isotropic radiated power measured was 2.44 micro-Watts, or -25.1dBm. Since the transmit frequency is greater than 1.5GHz, and the output power is less than 3 Watts, the EUT is categorically excluded from routine environmental evaluation per 47 CFR 2.1091(c). The MPE estimates are as follows: Table 1 in 47 CFR 1.1310 defines the maximum permissible exposure (MPE) for the general population as (f MHz /1500) mW/cm 2 . The exposure level at a 20 cm distance from the EUT’s transmitting antenna is calculated using the general equation: S = (PG)/4πR 2 Where: S = power density (mW/cm 2 ) P = power input to the antenna (mW) G = numeric power gain relative to an isotropic radiator R = distance to the center of the radiation of the antenna (20 cm = limit for MPE estimates) PG = EIRP Solving for S, the maximum power density 20 cm from the transmitting antenna is summarized in the following table: The power density does not exceed 1.0 mW/cm 2 at 20 cm; therefore, the exposure condition is compliant with FCC rules. The applicant’s radio, FCC ID: OXZWBPV2006, is compliant with the requirements of 47 CFR 1.1310.
