10. CLEANING (WA-1822C only) 10.1. Cleaning the Head, Capstan and Pinch Roller If the cassette deck is used for prolonged periods of time, its heads, capstans and pinch rollers will become dirty. As a result, sound output could be affected by lower output, a reduction in high-frequency sound output or irregular pinch roller rotation. To avoid these problems, periodically clean these parts with a commercial cleaning tape or a cotton swab dampened in alcohol.
11. ABOUT CASSETTE TAPES Normal tape • Use only normal bias tape. Do not use the chrome or metallic tape. If other varieties of tape than Normal Bias are used, the sound output may become displeasing to the ears or previous recordings may not be erased when re-recording. • Do not play tapes recorded with noise reduction. Sound quality may be drastically affected if tapes recorded with such noise reduction circuitry as Dolby are played back. Always use tapes recorded without noise reduction.
12. ABOUT EXTERNAL EQUIPMENT 12.1. Using External Speaker [Recommended External Speaker and Stand] Speaker: A rated input of 20 W or more, and impedance of 8 – 16 Ω. Stand: Mount the speaker on the TOA ST-16, or other stand. Notes • Note the correct polarities when connecting an external speaker. • Take care that the External speaker terminals are not shorted during connection. Step 1. Connect the external speaker to the External speaker terminal. Step 2.
12.2. Using an External CD Player or Cassette Deck (for Playback) Step 1. Connect the CD player or cassette deck line output to the unit's External Input terminal using a pin cable. Input sensitivity is –20 dB, 10 kΩ. (0 dB = 1 V) Step 2. Adjust the volume with the External Input Volume control. Note The External Input is monaural. Even if the input signal is stereo, it is played back in single-channel monaural.
13. TROUBLESHOOTING Symptom Cause Remedy The power indicator lamp does not light even when the power switch is set to the ON position. (Power is not supplied.) [When operated on AC power] The power plug is not connected to an AC outlet. Insert the power plug into the AC outlet. [When operated on batteries] Batteries not inserted with correct polarities.
