  • Page 4: Electrostatically Sensitive(Es)Devices

    Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors and semiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity. 1.

    Subject: No Output in Surround Modes In early versions of the AVR35, AVR45 and AVR65, the IC484 +5v regulator may overheat and go into thermal protection. Its +5 volt output will cease; when this happens the AC-3 and Surround Processor cannot function normally, and the audio output may go dead, or experience a long delay before any surround mode comes on.
