User manual AUDIOVOX ASH300 OWNER INSTALLATION MANUAL

[. . . ] Your system will detect and notify the driver with 3 distinct "Tones" (beeps), which correspond with your vehicle's distance to objects in the detection zone. Upon engaging into reverse gear, you should hear 1 distinct tone. This serves multiple functions: 1) Notification that the system is active and is scanning for objects in the detection field. [. . . ] Using a Toothpick, or similar non-metal "probe", insert it into programming port and press and hold for at least 5 seconds, then release. Upon releasing the reprogramming button, you will hear one long confirmation chirp. After reprogramming, test the system by slowly backing toward a large object that will be detected in each zone. If you still experience problems, call (800) 225-6074. -4- Troubleshooting (For additional information, please contact your installation center. ) Symptom No Function in Reverse Remedy Check power to receiver and transmitter Reprogram Receiver Check Fuse in Receiver Check in-line fuse in Sensing Unit Check 7-way harness Check Ground Wire Refer to page 4 Reprogramming Wireless Receiver. Inconsistent Operation Constant Tone in Reverse Always check for object behind vehicle Make sure sensors are clean of debris Care To prevent power wire harness damage, remove Hitch Unit and unplug all power wires prior to driving through automatic car washes. Keep sensors clear of any solid mass or debris to maintain accurate performance. -5- Situations Where Momentary, or No Detection is Experienced Your system utilizes highly advanced Ultrasonic technology to locate objects in your vehicle's path. Under some circumstances however, an object may not be detected. Always use extreme caution when reversing, looking behind your vehicle and maintaining speeds of less than 3 miles-per-hour. A small object, which is under your bumper or too close to the vehicle, may not be detected due to the dispersion of the sensor's signal. When reversing down a steep slope or driveway, gravel and/or the road surface may cause momentary detection signals due to the sensors following the sloping angle of the vehicle Reversing on loose gravel, rough surfaces, and pot holes may produce intermittent detection due to the signal bouncing off of reflective surfaces behind the vehicle. -6- Reversing at an angle towards a partial wall or other large flat surface may refract ultrasonic signals, causing an object not to be detected. If reversing towards a 90 degree angle, such as a corner of a wall or pillar, sensor detection pattern will refract as shown until vehicle is close enough to receive signal back from corners. In such situations, vehicle could reach very close distances before detecting. Due to natural projection angle of the sensors, a natural "no coverage" area is common with the system at the outer corners of the vehicle. This may occur at about 010" from the bumper's outer corners. -7- Installation Guide This Hitch-Mounted Wireless Reverse Obstacle Detection System is for Trailer Hitch Heights Over 15" From Road Surface. -8- Your system can be installed with a few easy steps, providing your vehicle comes equipped with a 7-way connector socket and a standard 2" Hitch Receiver. If your vehicle is not equipped with a 7-way connector, you can obtain a power connection using the provided 2-pin reverse power hardwire kit and retreive power at the reverse light harness. You can begin by inserting the 7way plug into the vehicle's 7way socket, (Fig. A). Insert the Sensing Unit into the Trailer Hitch of the vehicle, (Fig. B). Use the HitchLock to secure the 2" sleeve and the Sensing Unit into the vehicle's trailer hitch receiver, (Fig. C). The RF Receiver will be plugged into the vehicle's cigarette lighter, or similar 12 volt port. (Fig. D) -9- Hitch Receiver Conversion and Hardwire Kit Most vehicles come equipped with a 1¼" or a 2" trailer hitch receiver. Your system can be converted to fit the vehicle's receiver by simply sliding the 2" sleeve (A), off the center of the 1¼" system shaft for use on 1¼" hitch receivers. The hitch-lock kit (C, D, E) comes with 2 sizes of pin shafts (C and D) to accommodate the 2" and 1¼" hitch pin holes. Included are rubber hitch lock spacers (G) designed to take up slack between the hitch receiver pin holes and hitch-lock. The foam stabilizers (F) are included to take up slack between unit and vehicle's hitch receiver. If your vehicle does not have a 7-way trailer plug, your system includes a 2-pin reverse power harness kit (H). [. . . ] Defective parts are exchanged on a part for part basis. No returns will be accepted without an approved Return Authorization Number (R. A. #) from the company. Replacement parts will be issued upon receipt of returned goods and following verification of defective status unless other arrangements are approved. [. . . ]
