12. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP3 (Lch), TP1 (Rch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000 Hz ± 5 Hz (FWD) and FWD speed ± 45 Hz (REV) with respect to forward speed. 13. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP3 (Lch), TP1 (Rch) � Adjustment location : Head azimuth adjustment screw Method : Play back (FWD) the 8 kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode. 14. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP3 (Lch), TP1 (Rch) Method : Play back the 315 Hz and 8 kHz signals of the test tape and check that the output ratio of the 8 kHz signal with respect to that of the 315 Hz signal is within 5 dB. 15. PB Sensitivity Check (DECK 1, DECK 2) Settings : � Test tape : TTA�200 � Test point : TP3 (Lch), TP1 (Rch) Method : Play back the test tape and check that the output level of the test point is 140 mV ± 3 dB. 16. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP3 (Lch), TP1 (Rch) � Input signal : 1 kHz / 8 kHz (LINE IN) (-20 VU) � Adjustment location : SFR351 (Lch) SFR352 (Rch) Method : Apply a 1 kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP3, TP1 becomes 0 dB (10 mV). Record and play back the 1 kHz and 8 kHz signals and adjust SFRs so that the output of the 8 kHz signals becomes 0 dB ± 1 dB with respect to that of the 1 kHz signal. 17. REC/PB Sensitivity Check (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP3 (Lch), TP1 (Rch) � Input signal : 1 kHz (LINE IN) (0 VU) Method : Apply a 1 kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP3, TP1 becomes 0 dB (100 mV). Record and play back the 1 kHz signals and check that the output is -1 dB ± 3.5 dB.

18. µ-CON OSC Adjustment Settings : � Test point : TP10 (KEY SCAN) TP11 (DGND) � Adjustment location : L101 Method : Insert AC plug while pressing POWER key and TUNER function key. Connect a frequency counter across TP10 and TP11. Then adjust L101 so that the frequency at the test point becomes 208.80 Hz ± 0.21 Hz. [Manual Reset] Make up for RESET after adjustment. * Reset is to press POWER key while pressing CLEAR (STOP) key.
