T AUDIO FEATURES 1. Antitheft System To deter audio unit theft, the system is designed to accept a code number that makes the audio unit inop- erable if it is removed from the vehicle and then reconnected without inputting the correct code number. 4 If the antitheft system is activated, the unit will not operate and a code will flash on the display until the correct code is entered. 2. Headrest Speaker Headrest speakers are available. 3. Preset Memory A total of 18 broadcasting stations on AM, FM1, and FM2 bands can be quickly and easily set. 4. Automatic Memory By using the automatic memory function, which is independent from the preset memory, station selec- tions can be easily made in an area where the broadcasting station frequencies are not known. 5. Clock The clock display is incorporated within the audio display. 6. Metal Tape Automatic Detection The tape player automatically detects the use of metal tape and makes internal adjustments for metal tape playback. The word "METAL" is shown on the display. 7. Display Lights The unit's display lights can be switched on or off as desired. 8. Bodysonic System In order for sufficient bass reproduction to be possible in a car audio system, a large-diameter woofer must be equipped. However, these woofers are space consuming. With the bodysonic system, the "bass ,, sensation" can still be felt, ever without a woofer. 9. Auto Level Controller (ALC) If the optimum bodysonic level is set when the car is stopped, the level will feel insufficient due to vehicle vibration when the car is running. The autolevel controller automatically adjusts the bodysonic level to . . the appropriate amount at any speed. 45UOTX-221 Gartner Banana
