Sony CDX-C4750 Operating Instructions (primary manual) - Page 23

Do not expose the discs to direct sunlight or heat sources such as hot air-ducts, or leave them in a car parked in direct sunlight where there can be a considerable rise in temperature inside the car. Maintenance Fuse replacement When replacing the fuse, be sure to use one matching the amperage rating started on the original fuse. If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after replacement, there may be an internal malfunction. In such a case, consult your nearest Sony dealer. Before playing, clean the discs with an optional cleaning cloth. Wipe each disc from the center out. Do not use solvents such as benzine, thinner, commercially available cleaners, or antistatic spray intended for analog discs. Fuse (10 A) Note on moisture condensation On a rainy day or in a very damp area, moisture may condense on the lenses inside the CD player. Should this occur, the unit will not operate properly. In this case, remove the disc and wait for about an hour until the moisture evaporates. When you play 8 cm (3 in.) CDs Use the optional Sony compact disc single adapter (CSA-8) to protect the CD player from damage. Warning Never use a fuse with an amperage rating exceeding the one supplied with the unit as this could damage the unit. Cleaning the connectors The unit may not function properly if the connectors between the unit and the front panel are not clean. In order to prevent this, open the front panel by pressing (RELEASE), then detach it and clean the connectors with a cotton swab dipped in alcohol. Do not apply too much force. Otherwise, the connectors may be damaged. Main unit Back of the front panel Notes • For safety, turn off the engine before cleaning the connectors and remove the key from the ignition switch. • Never touch the connectors directly with your fingers or any metal device. 23
