Also avoid locations subject to vibration and excessive dust, heat, cold or moisture. Keep it away from sources of hum such as transformers or motors. 3. [. . . ] However, if you feel that your recording needs further bias adjustment (to compensate for absent or distorted high frequencies), adjust this control to your liking. When high frequencies are distorted, increase the recording bias by turning the BIAS ADJUST control clockwise. When high frequencies are absent, decrease the recording bias by turning the BIAS ADJUST control counterclockwise.

If a blank interval longer than 4 seconds is desired, keep pressing the button as long as you want. When the MUTE/SEARCH button is released, the deck enters Rec/Pause mode after making a 4-second blank interval. 0-STOP OPERATION - To return to the "0000" point During recording RESET 3 !

DOLBY HX PRO DYNAMIC BIAS SERVO SYSTEM This unit incorporates the Dolby HX Pro system which automatically controls the effective bias to reduce distortion and noise, improving high frequency response during recording. Tapes recorded with this system retain the same high quality even when played back on any other cassette deck.

Make sure that all power cord connections between the timer and amplifier/receiver are properly made. For details, refer to the instructions of your audio timer. No change in any of the other connections between the deck and amplifier/receiver, etc. , is necessary.

Thus, you can safely protect a recording for as long as you wish without fear of accidental erasure. Should you wish to use a cassette tape protected in this way for recording, simply covering the hole with adhesive tape will permit erasure and rerecording. ÷ When using Chrome (Type II/HIGH <CrO2>) or Metal (Type IV/METAL) tapes, make sure you do not cover the hole intended for the Auto Tape Selector operation. AUTO TAPE SELECTOR DETECTION SLOTS The deck has a built-in Auto Tape Selector which automatically adjusts for the proper bias, level and equalization according to the tape formulation -- all you have to do is load a cassette and the Auto Tape Selector does the rest. The Auto Tape Selector determines which type of tape is loaded by sensing detector slots in the top of the tape shell. Each tape formulation has its own characteristic hole markings standardized by the tape industry. ÷ Early model Metal (Type IV/Metal) tape formulation cassette shells do not have the slots for Auto Tape Selector operation. As a result, early model Metal type tapes recorded on another deck will be played back with the deck at the Chrome (Type II/HIGH <CrO2>) settings. YAMAHA does not recommend using this kind of tape. ÷ The deck does not have the required setting for Ferrichrome (Type III/FeCr) tape, since this tape formulation is not widely used. Should you use a Ferrichrome tape, it will be recorded and played back at the Normal (Type I/NORM) settings, which will result in an unnatural high frequency emphasis. 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.
