  • Page 14 WARNING DANGEROUS VOLTAGES, capable of causing death or serious injury, are present on the external terminals and inside the equip- ment. Use extreme caution and follow all safety rules when han- dling, testing or adjusting the equipment. However, these internal voltage levels are no greater than the voltages applied to the exter- nal terminals.
  • Page 15 PRODUCT CAUTIONS Before attempting any test, calibration, or maintenance procedure, personnel must be completely familiar with the particular circuitry of this unit, and have an adequate understanding of field effect devices. If a component is found to be defective, always follow replacement procedures carefully to that assure safety features are maintained.
