(2)音控头倾斜度调整这一程序必须在更换音控头和压带轮之后进行。重放空白磁带的开始部分,并确定磁带是否在P_4杆的上限和下限之间走带。如在磁带的最低点或最高点出现波动或皱折,转动音控头后面的螺钉(B)以调整音控头的倾斜度。见图21。 (3)音控头高度调整这一步骤只有更换音控头时才能进行。随着磁带转动,用检查灯观察音控磁头下沿并检查磁带的底部是否沿着音控磁头的下沿运转。如果不是这样,稍微转动音控磁头后面的螺母C(见图22),
(2) ADJUSTABLE TILT ADJUSTMENT This procedure must be performed after replacing the voice head and pinch roller. Replay the beginning of the blank tape and determine if the tape is to be transported between the upper and lower limits of the P_4 lever. If there is any fluctuation or wrinkle at the lowest or highest point of the tape, turn the screw (B) on the back of the audio head to adjust the pitch of the audio head. See Figure 21. (3) audio head height adjustment This step can only be replaced when the audio head. As the tape rotates, check the lower edge of the voice control head with the check lamp and check that the bottom of the tape runs along the lower edge of the voice head. If this is not the case, turn the nut C behind the head (see Figure 22)
