CAUTION: Before servicing receivers covered by this service manual and its supplements and addenda, read and follow the SAFETY PRECAUTIONS.
- Page 8 Warning and Cautions by this service manual might be equipped. 7. Do not apply AC power to this instrument and/or any of its electrical assemblies unless all solid-state device heat sinks are correctly installed. 8. Always connect the test receiver ground lead to the receiver chassis ground before connecting the test receiver positive lead.
- Page 9 Warning and Cautions CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise even some normally harmless motions such as mutual brushing of your clothes’...
- Page 10 Warning and Cautions boards using the familiar round hole, use the standard technique as Outlined . Removal Desolder and straighten each IC lead in one operation by gently prying up on the lead with the soldering iron tip as the solder melts. Draw away the melted solder with an anti-static suction-type solder removal device (or with solder braid) before removing the IC.
- Page 11 Warning and Cautions Securely crimp each connection and solder it. Inspect (on the circuit board copper side) the solder joints of the two “original” leads. If they are not shiny, reheat them and if necessary, apply additional solder. Fuse and Conventional Resistor Removal/Replacement 1.
- Page 12 Warning and Cautions 2. Trace along the copper pattern from both sides of the pattern break and locate the nearest component that is directly connected to the affected copper pattern. 3. Connect insulated 20-gauge jumper wire from the lead of the nearest component on one side of the pattern break to the lead of the nearest component on the other side.
