BASS CONTROL i) Press the "SEL" button to select the bass mode until "BAS" indicator lights up. ii) Press " " or " " button to adjust the bass effect. TREBLE CONTROL i) Press the "SEL" button to select the treble mode until "TRE" indicator lights up . [. . . ] * Do not allow such volatile agents as benzine, thinner, or insecticides to come Into contact with the surface of the front panel. * Never try to disassemble the front panel. NOTE: Do not try to insert another disc when one has been already inserted. Handle the disc by its edge, and to keep the disc clean, do not touch the surface. 5 DISC PLAY Cleaning discs Before playing, clean the disc with a clean, lint-free cloth. Wipe the disc in the direction of the arrow. Do not stick paper or tape on the disc. Do not expose the disc to direct sunlight or heat sources such as hot air ducts, or leave it in a car parked in direct sunlight where there can be a considerable rise in temperature. 6 7 8 9 10 Note: Do not use solvents such as benzine, thinners, commercially available cleaners or antistatic spray intended for analogue discs. 11 12 Do not Insert a disc with the label surface down.

General Specifications Our general specification for the voltage range of operation is 10 to 16 volts DC . Voltage The voltage of a fully charged battery ( engine not running ) is approximately 12. 5 VDC. Once a load (items being powered represent the "load" ) is applied , the voltage will drop. How much the voltage is reduced will depend on the following: 1. Current draw (amount of amperage) The higher the draw the greater the voltage will drop. The size and length of the conductor (wire) supplying power. Converters Many boats incorporate convertors as a source for 12VDC when connected to shore power (110-120 VAC). Some converters put out a very clean DC supply where others may have a considerable amount of AC ripple noise under maximum load. This AC ripple noise is filtered by the boat battery when connected into the circuit, but when the battery is disconnected the amount of AC ripple noise can create major problems for audio products. Noise may result and the line fuse may fail .

[. . . ] Special circuitry in electronic tuned radios or AM trimmers in mechanically tuned radios, make up for some of this difference in optimum mast length for AM reception. ANTENNA CABLE Increasing the antenna lead cable ( adding extensions ) will reduce sensitivity of AM with electronic tuned radios. GROUND PLANES Ground planes are also important when considering antenna performance. Most automotive antennas are designed to be mounted on the metal body of the vehicle. [. . . ]
