[. . . ] Heed warnings - All warnings on the appliance and in the operating instructions should be adhered to. Follow instructions - All operating and use instructions should be followed. Water and Moisture - The appliance should not be used near water - for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, or near a swimming pool, and the like. Carts and Stands - The appliance should be used only with a cart or stand that is recommended by the manufacturer. [. . . ] 5) Next, check if the tape speed variable range satisfies the specifications below. Maximum tape speed: +12 % or more (3360 Hz or more) Minimum tape speed: -45 % or less (1650 Hz or less) 3-8. Playback Level Calibration 1) Set the controls as follows. Record track select switch: OFF Dolby B noise reduction on/off switch: OFF 2) Connect an AC volt meter to the TAPE OUT 1 through 4 pin jacks. 10 X-26 3) Playback the TCW-231 test tape and check the output level if it is -10 dBV (0. 3 V) ± 1 dB reading. 4) If the reading is not within the above range, adjust R106 ~ R406 on the R/P AMP PCB assy. 3-9. Playback Frequency Response Calibration 1) Set the controls as follows. Record track select switch: OFF Dolby B noise reduction on/off switch: OFF 2) Connect an AC volt meter to the TAPE OUT 1 through 4 pin jacks respectively. 3) Playback the TCW-284F test tape and adjust R103 ~ R403 so that the output level at 6. 3 kHz is 0. 5 dB lower than the 400 Hz output level. 4) Confirm that the output level at 12. 5 kHz is within ± 1 dB of the 400 Hz output level. 3-10. Erase Current Adjustment At adjusting the erase current, put a blank cassette tape to the transport and the track to be adjusted is put in REC mode. 5) Release the PAUSE button and start recording the signal. 6) After recording a certain length, rewind the tape to the start point of recording section. Then, playback the tape and check the level at TAPE OUT 1 ~ 4. If the AC volt meter reading is not within -10 dBV (0. 3 V) ± 0. 5 dB, adjust the pot R121 ~ 421 (22 k) on the R/P PCB assy. Overall Frequency Response Adjustment 1) Set the controls under the same condition as 3. 12 except the DOLBY switch. (The switch should be turned on. ) 2) Apply a 400 Hz, -35 dBV (18 mV) signal to the INPUT 1 and 2 phone jacks. 3) Record the signal, rewind and playback the recorded section of the tape and memorize the output level at TAPE OUT 1 ~ 4. 4) Next, apply 6 kHz & 12 kHz, -35 dBV (18 mV) signals to the INPUT 1 and 2 phone jacks. 5) Record the signal, rewind and playback the recorded section of the tape. 6) Check if the 6 kHz / 12 kHz output level at TAPE OUT 1 ~ 4 is within ± 2 dB comparing to the 400 Hz output level. If the AC volt meter reading is not within the above specification, adjust the pot R133 ~ 433 (220 k) on the R/P AMP PCB assy so that the recording level at 6 kHz will be within the specification. 3-14.
