1. LIQUID CRYSTAL DISPLAY PANEL In radio mode, the frequency, preset number, etc. will be shown on the display. In tape mode, the direction indicator appears on the display. 2. CASSETTE COMPARTMENT Insert the cassette with the exposed tape facing to the right. The unit will switch to TAPE mode automatically. 3. OFF/VOLUME Rotate the knob to switch the power on or off and to adjust the volume. BALANCE (push) Push and rotate the knob to adjust the sound balance between the left and right speakers. 4. FADER Rotate the knob to adjust the sound balance between the front and rear speakers. 5. TONE Rotate the knob to adjust the the high frequency sound level. 6. TUNE/SEEK/ATP (AUTO TUNING PRESET) CONTROL This button performs two functions: Auto Tuning Preset Scan and Auto Tuning Preset Memory. This function allows you to locate and store up to six stations in the selected band automatically. Select the desired band, then rotate the knob counterclockwise to select a station on a lower frequency or clockwise to select a station on a higher frequency. Hold the knob in either position for more than 0.5 seconds to begin automatic scanning. The tuner will locate and stop at the next receivable station. Auto Memory Scan Function Use this function to check the stations stored in memory. Press the ATP button to select the preset stations for five seconds each, beginning with the current station, Either press the ATP button again or press one of the preset buttons (1-6) to stop scanning. During the preset scan operation, the preset number flashes on the display.

Auto Memory Store Function This function automatically locates and stores up to six stations, starting from the current point on the selected band. Press and hold the ATP button for more than 2 seconds to begin the ATP operation. After automatically storing the station, preset scan will begin, starting with preset number 1. Preset scanning will continue until it is canceled. * If ATP is started in the DISTANT mode, the selected band will be scanned once. * If ATP is started in the LOCAL mode, the selected band will be scanned up to three times - twice in the local mode, then once in the DISTANT mode. * If ATP is started while a preset station is selected, the current preset station will be replaced by the next available station on the selected band. (Some other preset stations may also be replaced, depending on signal strength.) 7. EJECT ( ) Push this button to eject the cassette. 8. FAST FORWARD/REWIND/DIRECTION BUTTONS Forward Play Mode Fast Forward: Press Rewind: Press Reverse play Mode Fast Forward: Press Rewind: Press Direction: Press both buttons simultaneously to change the direction of tape travel. 9.

INSTALLATION
1. First, determine the correct shaft spacing required for your vehicle, then adjust the spacing as necessary. 2. Install one shaft boot on each control shaft. 3. Install one shaft nut and one shaft washer on each control shaft. Determine the correct positions for the shaft nuts by placing the unit in the dashboard. 4. From behind the dashboard, insert the unit through the dash opening. If the unit protrudes too far, or not far enough, adjust the position of the shaft nuts. (Once the correct position is found, it may be necessary to cut off excess material to shorten the shaft boots.) 5. Attach the rear support bracket to the threaded stud on the rear of the stereo using the supplied nut. 6. Attach the free end of the rear support bracket to the vehicle with the screw provided. 7. Secure the front of the unit with the supplied shaft washers and nuts. NOTE: The faceplate is provided for use on automobiles which have enough space surrounding the radio to accept the plate. Attach the faceplate to the stereo by mounting the nuts and washers in front of the faceplate. (If the shafts have been moved to the extreme outside position, it may be necessary to widen the openings in the faceplate by using a round file.) 8. Attach the knobs to the control shafts.
