SA-HT845E / SA-HT845EG 1 Use of Active Subwoofer 1.1. Checking Player when Active Subwoofer is not used 1. This unit uses the active subwoofer to supply the power of the component, and the active subwoofer should be connected to the component to check operational conditions of the component.
Page 6: Safety Precautions
SA-HT845E / SA-HT845EG 2 Safety Precautions 2.1. GENERAL GUIDELINES 1. When servicing, observe the original lead dress. If a short circuit is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly installed.
Page 7: Before Repair And Adjustment (Using Active Subwoofer)
SA-HT845E / SA-HT845EG Caution Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage an ES device).
Page 8: Precaution Of Laser Diode
SA-HT845E / SA-HT845EG 6 Precaution of Laser Diode 7 About Lead Free Solder (PbF) Distinction of PbF PCB: PCBs (manufactured) using lead free solder will have a PbF stamp on the PCB. Caution: · Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher.
