4、261.0 Ci Meter, Signal Level6625-00-226-5680RA 2260.6 Ci Never remove radioactive components from cartons until you are ready to use them. Never place radioactive components in your pockets. CAUTION Use extreme care when handling radioactive components. Breakage could be haz- ardous. If any of these

5、 components are broken, notify the Radiological Protection Officer (RPO) immediately. The RPO will survey the area for radiological contamination and will supervise the removal of broken components. See qualified medical personnel and the local RPO immediately if you are exposed to or cut by broken

6、components. First aid and handling instructions for radioactive material are contained in TB 43-0116, and TB 43- 0122.

9、he equipment. When the technician is aided by op- erators, he must warn them about dangerous areas.Do not attempt internal service or adjustment unless another person is present who is capable of rendering first aid and resuscitation. A periodic review of safety precautions in TB 385-4, Safety Preca

10、utions for Maintenance of Electrical/Electronic Equipment, is recommended. Remove all rings and jewelary before working on equipment or applying power. Whenever possible, the power supply to the equipment must be shut off before beginning work on the equipment. Take particular care to ground every c

11、apacitor likely to hold a dangerous potential.When working inside the equipment, after the power has been turned off, always ground every part before touching it. Be careful not to contact high-voltage connections of 115 volts alternating current (vat) input power when installing or operating this e

12、quipment. Whenever the nature of the operation permits, keep one hand away from the equipment to reduce the hazard of current flowing through the vital organs of the body. Do not be misled by the term “Low Voltage”. Potentials as low as 50 volts can cause death under adverse conditions. C TM 11-5820

13、-520-34 Dangerous voltages exist in this equipment. Voltages as high as 128 vat, 3000 volts direct current (vdc), and 10,000 volts radio frequency (vrf ) are used in the operation of ampli- fier, radio frequency AM-3349/GRC-106. Dangerous voltages exist at the AM-3349/GRC-106 50 ohm and whip antenna

14、 connectors. Be careful when working around the antenna or antenna connectors. Radio frequency voltages as high as 10,000 volts exist at these points. Operator and maintenance personnel should be familiar with the requirements of TB 43-0129 before attempting installation or operation of radio set AN

15、/GRC-106 and radio set AN/GRC-106A. Use extreme care when loading or unloading equipment. Serious injury could result. To avoid injury to personnel or damage to equipment, only personnel engaged in the ac- tual loading or unloading operation should be permitted near the truck, lifting device, or ass

16、emblage. To eliminate confussion, all instructions must come from the loading crew supervisor. All personnel must remain clear of the truck while the assemblage is being lowered onto the truck. Before making any power connections, be sure that the generator set is turned off. Be sure that the centra

17、l power source is turned off before making any power connections. Adequate ventilation should be provided while using TRICHLOROTRIFLUOROETH- ANE. Prolonged breathing of the vapor should be avoided. The solvent should not be used near heat or open flame; the products of decomposition are toxic and ir

18、ritating. Since TRICHLOROTRIFLUOROETHANE dissolves natural oils, prolonged contact with skin should be avoided. When necessary, use gloves which the solvent cannot pen- etrate. If the solvent is taken internally, consult a physician immediately. Never attempt to lift heavy, awkward, or bulky equipme

19、nt alone. Serious injury could result. D TM 11-5820-520-34 Compressed air is dangerous and can cause serious bodily harm if protective means or methods are not observed to prevent chips or particles of any size from being blown into the eyes of personnel.Compressed air shall not be used for cleaning

20、 purposes except where reduced to less than 29 pounds per square inch (psi), and then only with effective chip guarding and personnel protective equipment. CAUTION Prior to equipment power down, rotate RT SERVICE SELECTOR to STANDBY, allow to cool to prevent damage to components. CAUTION Before conn
