NOTES ON SCHEMATIC DIAGRAM
N 1. PRODUCT SAFETY NOTICE
TLJ C COMPONENTS DESIGNATED BY A MARK { A ) 'N TH!S SCHEMATiC DIAGRAM
) n ElDESiGNATE COMPONENTS WHOSE VALUES ARE OF SPEOAL S!GN)F)CANCE
TO PRODUCT SAFETY. SHOULD ANY COMPONENT DESIGNATED BY A MARK NEED TO BE
REPLACED, USE ONtYTHE PART DESIGNATED )N THE PARTS LIST DO NOT DEBATE
FROM THE RESISTANCE, WATTAGE AND VOLTAGE RATINGS SHOWN.
N 2. NOTES ON SCHEMAHC DIAGRAM
Specification of capacitor and resistors wi!) be shown with coded symbofs, reading code symbols foifowing the chart and
notes. Some capacitor and resistors wi)) be shown directly with values and no other information. Detai)ed information on
each capacitor and resistor wi)) be shown in the list.
NOTE; DO NOT REPLACE OR ORDER RES)STOR AND CAPACITOR PARTS FOLLOW)NG THE SPECIFICATIONS
SHOWN )N THE SCHEMATIC DfAGRAMS.
ALWAYS CHECK FOR THE CORRECT SPEC)F)CAT)ONS )N THE PARTS UST. ESPEOALLY FOR CR)T)CAL COM-
PONENT MARKED A . SPEOAL ATTENT)ON MUST BE OVEN TO CRmCAL COMPONENTS.
13. READ)NG )N SCHEMADC D)AGRAM
Read resistor codes as foMows:
1. A!) resistance vafues are indicated in ohms: K==1.000- M=1,000,000.
2. Resistor which is indicated with resistance va!ue onty are 1/6W carbon resistor. Resistor which is indicated with material
to!erance and vatue are 1/4W rated wattage.
Read capacttor codes as foftows:
1. For capacitors identified with -j)-, va)ues tess than 1 are expressed in uF, values more than 1 are in pF.
2. For capacitors (e!ectro)ytic) identified with -^-. vatues are expressed in uR
Vottage and waveforms were taken using a video co!or bar signal (1V p-p at 75 ohms terminated) and controfs to nor-
ma).
Voitages were taken with a high-impedance vottmeter.
14. SERViCE NOTES;
1.When repiacing high wattage resistors on circuit board, keep the resistor body 10 mm (3/8') from circuit board.
2. Keep wires away from high voitage and high temperature components-
