When the technicians are ai

10、ded by operators, they must be warned about dangerous areas. Whenever possible, the power supply to the equipment must be shut off before beginning work on the equipment. Take particular care to ground every capacitor likely to hold a dangerous potential. When working inside the equipment, after the

11、 power has been turned off, always ground every part before touching it. Be careful not to contact high-voltage connections or 115 volt ac input connections when installing or op- erating this equipment. Whenever the nature of the operation permits, keep one hand away from the equipment to reduce th

12、e hazard of current flowing through the body. Warning: Do not be misled by the term low voltage. Potentials as low as 50 volts may cause death under adverse conditions.

DEATH ON CONTACT or severe electrical shock may result if personnel fail to observe safety precautions. Learn the area of high voltage in each piece of equipment. Be careful

24、 not to contact high voltage connections when installing or operating this equipment. High voltages are present on the antenna during transmission. Do not touch or stand near the antenna when the equipment is energized. Make sure power is off before performing cleaning and inspection procedures. Ade

25、quate ventilation should be provided while using TRICHLOROTRIFLUOROETHANE. Prolonged breathing of vapor should be avoided. The solvent should not be used near heat or open flame; the products of decomposition are toxic and irritating. Since TRICHLOROTRIFLUOROETHANE dissolves natural oils, pro- longe

26、d contact with skin should be avoided. When necessary, use gloves which the solvent cannot penetrate. If the solvent is taken internally, consult a physician immediately.

28、LECTRICAL SHOCK, MOVE THE PERSON A SHORT DISTANCE AWAY AND IMMEDIATELY START ARTIFICIAL RESUSCITATION Change 1 E TM 11-5820-924-13 WARNING Should mission requirements necessitate operation of the transmitter in the lower frequency range, it is possible to receive minor RF shocks and/or bums from the

29、 radio set case, handset, or CW telegraph key, when keying the transmitter. Increasing the output power of Radio Frequency Amplifier AM-6874/PRC-104 above the specified 20 watt level may also result in RF shocks and/or burns. Adjustments to the amplifier gain are not authorized by the operator. In o

30、rder to reduce the possibility of receiving RF shocks and/or burns, note the following and take appropriate action, as required: oAvoid contact with exposed metal parts on the radio set case, handset, or telegraph key, when keying the transmitter. oBadly scratched surfaces and exposed edges should b

31、e painted (para 4-11, Corrosion Control). Painted surfaces are good insulators against shock. oWhen the radio set must be operated for an extended period of time at a single location, use of a grounding rod or counterpoise is recommended as a means of reducing the possibility of RF shocks and/or bur

32、ns and improving radio performance. *The likelihood of receiving shocks is greater in a humid or wet environment and when the operator is in direct contact with ground.
