[. . . ] 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. [. . . ] 3) Rotate the REC/PLAY head azimuth adjusting screw to obtain a maximum output level. 3-7. Tape Speed Check and Adjustment 1) Confirm that the Pitch control knob is at center position. 2) Connect a frequency counter or wow & flutter meter with frequency counter to the TAPE OUT. Press the NORMAL FIX button to change the tape speed at LOW and playback the Model 9152 test tape. 4) Adjust the tape speed by R49 (470 ) on the R/P AMP PCB so that the freuqency counter reading is within 1500 Hz ± 30 Hz. 5) Press the NORMAL FIX button to change the tape speed at HIGH and playback the Model 9152 test tape. 6) Adjust the tape speed by R48 (3. 3 k) on the R/P AMP PCB so that the freuqency counter reading is within 3000 Hz ± 30 Hz. Check the tape speed and wow & flutter if they satisfy the following specifications. Tape Speed: 3000 Hz ± 30 Hz at both BOT (beginning of tape) and EOT (end of tape) positions Wow & Flutter: 0. 25 % (CCIR WTD) at both BOT and EOT positions 7) If the tape speed is not within the above specification, adjust R43 (3. 3 k) on the R/P AMP PCB assy. 8) 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. 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 MIC/LINE IN 1/3 and 2/4 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 R132 ~ 432 (220 k) on the R/P AMP PCB assy so that the recording level at 6 kHz will be within the specification. 3-14. Measurement 1) Connect a distortion meter, 400 Hz HPF and 30 kHz LPF to TAPE OUT 1 ~ 4 and set the controls under the same condition as 3-12. 3) Playback the recorded part and check if the distortion level is less than 2 %. 3-15. Erasure Measurement 1) Connect a 1 kHz bandpass filter and AC volt meter to TAPE OUT 1 ~ 4 and set the controls under the same condition as 3-12. 2) Record a 1 kHz, 0 dBV (1 V) sine wave signal which is 10 dB higher than the reference recording level on a blank tape. 3) Rewind the tape to the start point of recording and advance it by a short length. Check if the level ratio between the playback level and nosignal section (erased part) is 67 dB or more. 3-16.
