Error messages Handling and Care of the Disc ➲ About error messages ➞ Appendix of the Operation Manual Some basic precautions are necessary when handling your discs. Vehicles that Cannot Obtain Speed Pulse Data The speed pulse data comes from the speed sensing circuit. The location of this speed sensing circuit depends on your vehicle model. In some cases, it is impossible to make a connection to it, and in such a case we recommend that the ND-PG1 speed pulse generator (sold separately) be used. • Be sure to connect the speed pulse lead. If not, vehicle location error will increase. Navigation map discs • Do not use discs other than those intended for this product. Use only discs approved by Pioneer. ➲ For suitable discs ➞ Page 6 ❒ If you wish to use other navigation discs, first check that they are compatible with this equipment and approved by Pioneer. DVD drive and care • Use only normal, round discs. If you insert irregular, non-round, shaped discs they may jam in the DVD drive or not play properly. Appendix Conditions Likely to Cause Noticeable Positioning Errors For various reasons such as the state of the road you are traveling on and the state of reception of the GPS signal, the actual position of your vehicle may differ from the position displayed on the map screen. Some types of vehicle may not output a speed signal while driving at just a few miles per hour. In such a case, the current location of your vehicle may not be displayed correctly while in a traffic jam or in a car park. • The current vehicle position cannot be dis- played exactly under all conditions, due to variations in satellite reception, road conditions, the vehicle's condition, and any objects in contact with the antenna. • Also, GPS reception may be unavailable during certain weather conditions, when driving in tunnels or garages, or when signal interference may occur such as when driving between tall buildings or near large vehicles. 20 • Check all discs for cracks, scratches or warping before playing. Discs that have cracks, scratches or are warped may not play properly. Do not use such discs. • Avoid touching the recorded (non-printed side) surface when handling the disc. • Store discs in their cases when not in use. • Keep discs out of direct sunlight and do not expose the discs to high temperatures. • Do not attach labels, write on or apply chemi- cals to the surface of the discs. • To clean dirt from a disc, wipe the disc with a soft cloth outward from the center of the disc. • If the heater is used in cold weather, condensation may form on components inside the DVD drive. Condensation may cause the DVD drive to not operate properly. If you think that condensation is a problem turn off the DVD drive for an hour or so to allow the DVD drive to dry out and wipe any damp discs with a soft cloth to remove the moisture. • Road shocks may interrupt disc playback.
