UMP9020 CARE AND MAINTENANCE Your new radio/CD player does not require any maintenance. However, proper understanding of its use and handling will help you obtain maximum enjoyment of its capabilities. We recommend that you keep this manual for reference on the many features of this unit as well as how to set the clock. The following points should be observed: • When cleaning the interior of the vehicle, do not get water or cleaning fluids on the unit. • The CD player is a precision instrument and will not operate properly in extreme heat or cold. If such conditions occur, wait until the interior of the vehicle reaches a normal temperature before using the player. • If the temperature inside the player gets too hot, a protective circuit will automatically stop play of the disc. In this case, allow the unit to cool before operating the player again. • Never insert anything other than a 5" (12 cm) compact disc into the player as the mechanism can be damaged by foreign objects. • Do not attempt to use 3" (8 cm) CD-Single discs in this unit, either with or without an adaptor, as damage to the player and/or disc may occur. Such damage will not be covered by the Warranty on this product. • When not using the disc player, always remove the compact disc. Do not leave an ejected disc sitting in the disc slot as this can expose it to sunlight and other causes of damage. • Do not attempt to open the unit chassis. There are no user-serviceable parts or adjustment points inside. • When the vehicle warms up during cold weather or under damp conditions, condensation may appear on the lens of the disc player. Should this occur, the player will not operate properly until the moisture has evaporated. • The unit is designed with a vibration dampening CD mechanism to minimize interruption of disc play due to normal vibration. When driving on rough roads, however, occasional sound skips may occur. This will not scratch or damage the disc and normal play will resume when the rough conditions cease. Handling Compact Discs Dirt, dust, scratches and warping can cause skips in the playback and deterioration of sound quality. Please follow these guidelines to take care of your compact discs: 17 • Carefully wipe fingerprints, dust and dirt from the disc's playing surface with a soft cloth. Wipe in a straight motion from the center to the outside of the disc. • Never use chemicals such as record sprays or household cleaners to clean CDs, as they can irreparably damage the disc's surface. • Discs should be kept in their storage cases when not in use. • Do not expose discs to direct sunlight, high temperatures or high humidity for long periods. • Do not stick paper, tape or labels on disc surfaces.
