After turning on the power to each component, select the station on your tuner which you want to record and turn down the volume on your amplifier/receiver. This will have no effect on the recording signal level. Remember to set the proper recording level. Set the timer to the desired recording start and stop times. It is advisable to set the timer to begin recording slightly before and end slightly after the actual broadcast receiving time to leave some room for later editing. Set the TIMER switch to the REC position. TIMER REC OFF PLAY Timer playback 1. Turn on the amplifier/receiver and adjust the volume and tone controls. Set the input mode selector of your amplifier/receiver to the cassette deck function mode. Set the timer to the time you wish to start and stop playback. Set the TIMER switch to the PLAY position. TIMER REC OFF PLAY 5. This effect may be compensated for somewhat by adjusting the BIAS ADJUST to the plus (+) direction during recording, or by using the PLAY TRIM control and/or the tone controls of your amplifier/receiver during playback. TYPE II TYPE IV TAKING UP SLACK IN THE TAPE As a precaution against tape entanglement and damage, remove any slack in the tape before inserting cassettes into the deck. This is accomplished by inserting a pencil, pen or similar object into one of the spools and gently winding it until all the slack is removed. Be careful not to touch the tape part itself. It is very delicate and touching it may damage the tape and its recorded contents. Detector slots Detector slots STORING CASSETTES After putting a cassette tape back into its case, store it in a location away from exposure to direct sunlight, humidity, high temperatures, and magnetic fields (away from television sets, speakers, etc. ). High temperatures and humidity will damage the tape itself, while exposure to magnetic fields may cause a loss of recorded material. Avoid touching the tape surface with your fingers, since dirt or finger oil will contaminate the deck's heads. 14 To open the sub panel To close the sub panel OPTIONAL REMOTE CONTROL TRANSMITTER With the optional remote control transmitter RKX1, you can operate this unit at your listening position.

Normal use will cause an accumulation of dirt and dust on the heads, capstans, and pinch rollers. This can lead to poor sound quality, drop outs (intervals with no sound), unsteady tape speed, loss of high frequency response, etc. Thus, clean the heads and all surfaces over which the tape travels with a commercially available cleaning cassette and fluid type cleaner. Inside of the cassette compartment Heads Capstan Pinch roller DEMAGNETIZATION After 20-30 hours of use, enough residual magnetism will build up on the heads to cause poor high frequency reproduction.
