These precaution

3、s must be thoroughly understood and apply to all phases of operation and maintenance. Keep Away From Live Circuits Operating personnel must at all times observe normal safety regulations. Do not replace components or make adjustments inside the equipment with high voltage turned on. To avoid casualt

4、ies, always remove power. Shock Hazard Do not attempt to remove the RF transmission line while RF power is present. Do Not Service or Adjust Alone Under no circumstances should any person reach into an enclosure for the purpose of service or adjustment of equipment except in the presence of someone

5、who is capable of rendering aid. Safety Earth Ground An uninterruptible earth safety ground must be supplied from the main power source to test instruments. Grounding one conductor of a two conductor power cable is not sufficient protection. Serious injury or death can occur if this grounding is not

6、 properly supplied. Chemical Hazard Dry cleaning solvents for cleaning parts may be potentially dangerous. Avoid inhalation of fumes or prolonged contact with skin. Resuscitation Personnel working with or near high voltages should be familiar with modern methods of resuscitation. RadioFans.CN 收音机爱 好
