SONY DPPSV88 VOLUME 1
Service Manual

(Example) Assume that the first display is (R2-4) and that the difference between the display and head resistance value is 350 Z (the resistance value of a new head is higher). The display after replacement is (R35). (Since the difference the display and head resistance value is 290 Z or more, the step of R automatically increase by one step. The step of a numeric character also increases by one step because of 350 _ 290 = 60. For the step of a numeric character, the width of one step is approximately 73 Z. Therefore, the step of the numeric character increases or decreases by one step if the difference is 36 to 37 Z or more.) 9. Move a \ mark using Direction keys so that it is located in Rx (x = 1 to 8) obtained by the difference between the display and head resistance value. (In Fig. 3-7, a \ mark is located in R3.) Press the Print key when the \ mark is moved to the determined �Rx� position. 10. Printing is initiated and the screen (shown in Fig. 3-8) is displayed on the monitor screen.

11. After the printing is completed, move the \ mark to the determined numeric character (�5� because of (R3-5) in this example) using Direction keys and press the Enter key. (Fig. 3-9)
