"Back-up" memory Th is is the f u nction wh ich preserves the preset memory and most-recent memory functions. ln the event of a power failure, or if the power cord of the tuner is disconnected from the electric outlet, the back-up memory will preserve the preset memory and most-recent memory f u nctions for as long as approximately one week. TO PREVENT ERASING THE MEMORY 1. Be sure to connect the power cord of the tuner to the "UNSWITCHED" power outlet of the amplifier to be used. 2. lf the power supply is interrupted for one week or longer, the memory settings will be erased. For example: 1) lf the power cord is disconnected f rom the electric outlet, 2) lt an audio timer is used and the timer does not operate the tuner for a week or longer, 3) lf a power failure occurs, etc. lf any of the above occurs, the memory will have to be reset. The memory in this unit is maintained by a gold capacitor. lf the power supply is interrupted for a week or longer, set the power switch of the tuner to the "on" position for thirty minutes or more in order to recharge the gold capacitor. Note: lf the FM allocation setting is set to o.o5 MHz, the AM 1 kHzlstep frequency range becomes 530 - 1620 kHz. 0- 3 www.hifiengine.com

Note: It will not illuminate if the FM mode selector is set to the "mono" position. O fn[ lF band indicators (FM auto lF) normal[]: This indicator will illuminate if the signal is strong and there is little effect f rom interference. super narrow fT: This indicator will iluminate if the signal is weak an d/or there is interference. The illuminatton of the left and/or right parts of the indicator indicates that interference waves are present within 300 kHz (left: -, right: +) of the tuned frequency. O Quartz-lock/FM muting off indicator (quarlz lock/FM muting off) This indicator illuminates when this unit is precisely tuned to the transmission f requency of a radio broadcast. Note that this indicator may illuminate if the FM muting offlscan level selector has been set to the "off" position in order to receive a week radio broadcast. O Digital display The broadcast frequency, scan level indication of the FM muting offlscan level selector, the frequency of the recording level signal (0.33 kHz), and the FM signal strength are displayed. @ Memory indicator (memory) This indicator illuminates when the memory button is pressed. To preset the memory manually, press the desired preset tuning button while this indicator is illuminated (within approximately 4 seconds). lf the memory is preset automatically, the indicator will not illuminate. O Channel display The channel number selected by the preset-tuning buttons is displayed O Preset-tuning buttons (1-16) (FM/AM random 16ch preset tuning) These buttons are used to preset FM and AM broadcast frequencies into the memory of this unit, and are also pressed to select the desired preset f req uencies. lf the button is pressed momentarily, stations will be preset to channels 1 -B (f ront channels). lf the button is pressed slightly longer, stations will be preset to channels 9-16 (back channels) Note: Refer to page 8 for information concerning preset memory. 6 www.hifiengine.com

FM: Press this button to listen to an FM broadcast. FM allocation: A frequency step of either FM 0.2 MHzor FM 0.05 MHz can be selected. Set to the appropriate position for your locality. When the FM button rs pressed slig htly longer and then released when the "AL 5" indication illuminates, the FM f requency "step" will change to 0.05 MHz (50 kHz). To return to the original FM 0.2 MHz, press the FM button slightly longer, and then release it when the "AL 20" indication illuminates. AM: Press this button to listen to an AM broadcast. AM allocation: A frequency step of either AM 10 kHz or AM 9 kHz can be selected. Set to the appropriate position for you r locality. When the AM button is pressed slightly longer and then released when the "AL 9" indication illuminates, the AM frequency "step" will change to 9 kHz. To return to the original AM 10 kHz, press the FM button slightly longer, and then release it when the "AL 10" indication il luminates. @ Control panel door release (push open) lf any of the controls and selectors O through @ are to be operated, press this button to open the glass door. When this button is pressed, the glass door will open slowly by means of a damper mechanism. @ Memory button (memory) This button is used when preset memory setting of the preset-tu n ing buttons is made. There are two types of memory presetting: manual and automatic. Refer to page B for information concerning preset memory. @ Tuning buttons (tuning) These buttons are used for tuning to the desired broadcast stat io n. lf the button is pressed momentarily and then released, the f requency will change at intervals of 0.2 MHz (or 0.05 MHz) for FM and 10 kHz (or 9 kHz) for AM. lf the button is pressed slightly longer and then released, the station will be selected automatically. lf the broadcast signals are weak, it may not be possible to make automatic selection. lf this occu rs, make the selection manually. down: When this button is pressed, the frequency will change to a lower f req uency. up: When this button is pressed, the frequency will change to a h ig her f req uency. FM mode selector (mode) This unit automatically switches into the stereo mode when a stereo broadcast is received. Press this button to listen in the monaural mode. The FM stereo indicator will not illuminate in the monaural mode. FM muting offlscan level selector (muting) This selector is used when releasing the FM broadcast muting function and when setting the scan level for FM broadcasts. Stat ion (D FM lF band selector (tF band) For selection of the FM lF band. The built-in computer of this unit detects the signal condition and f unctions accordingly to select the FM lF band automatically. This button is used to change it manually. (D FM signal-strength indication button (signal) lf this button is pressed during reception of an FM broadcast, the signal strength (the strength of the signal of the broadcast being received) will be displayed within a 2 dB acc u racy . If the strength of the signal being received is 50 dB or more, a symbol (r ) will appear between the number and dB to indicate that a strong signal of 50 dB or more is being received. The signal will become saturated at 50 dB or more. ln order to resume the f requency display, press the button once again. (p Record level check button (rec level) This button is to be used for adjustment of the recording level when recording an FM broadcast. When this button is pressed, the microcomputer f unctions to emit a reference signal of precisely 333 Hz trom the output terminals of this unit. The word "CAL" (calibration) and then, soon thereafter, "0.33 kHz" will be shown by the digital d isplay. Adfustment ol the recording level Use the input-level control(s) of the tape deck to make the adjustment while watching the recording-level meters. o For VU meters and level meters. Adjust so that the indication is about +2 VU or +2 dB. o For peak-level meters: Adjust so that the indication is about -2 dB. Notes: 1) Because the ideal recording level is apt to vary depending upon the program source and the characteristics of the tape deck, the adjustment should be made by also considering those factors. 2) Don't press the operation buttons of th is un it d uring a recording. lf they are pressed, the recorded sound may be d istu rbed. Releasing the muting lunction (off) ln mountainous areas, etc., where broadcast signals are weak, breakup in the sound can be lessened by lightly pressing the button. When this is done, the muting is released only for the station being received. However, when a tuning button is pressed to begin scanning again, the former scan level will be used. Setting the scan level (scan level) This level setting is effective only for the automatic preset memory and auto tun ing. When the button is held down, "dB" will be displayed and the numbers 30,40, and 50 will be displayed in order. When the desired level is reached, release the button. The higher the level, the more noise is reduced. Stations with good reception can use " a high level", but stations below the set level cannot be received. ln order to receive these station, the level has to be reset. , dB Er I o r-.X," rB l^ ) 6 lr-Io r*t;: ::, rE n g.3at- ABD,E .. ffi,-=- l'l; si 'E a a (D @ 7 www.hifiengine.com
