(In addition to this, the necessary note is printed in each block.) For schematic diagrams. Note: · All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. · All resistors are in and 1/4 W or less unless otherwise specified. · C : panel designation. Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. Note: Les composants identifiйs par une marque ! sont critiques pour la sйcuritй. Ne les remplacer que par une piйce portant le numйro spйcifiй. WAVEFORMS ­ BASE UNIT SECTION ­ 1 4 Vp-p 6-1.
