SA-HR45E / SA-HR45EG 1 Safety Precautions 1.1. 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.
SA-HR45E / SA-HR45EG 2. Determine the cause of the problem and correct it. 3. Press the STANDBY /ON button once again, supply the power. Note: When the protection circuitry functions, the unit will not operate unless the STANDBY /ON button is first switched STANDBY and then ON again.
SA-HR45E / SA-HR45EG to the chassis or circuit assembly into which the device will be installed. Caution Be sure no power is applied to the chassis or circuit, and observe all other safety precautions. 8. Minimize body 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).
