27、20-357-10. 2 CHAPTER 2 INSTALLATION 3. Unpacking a. Packaging Data (fig.1). When packed for ship- ment, the components of Radio Receiver R-390/URR are placed in a carton which is packed in a wooden shipping crate (fig.1). The wooden shipping crate is 21 inches high, 32 inches wide, and 32 inches dee

28、p. Its volume is approximately 12.4 cubic feet and the total packed weight is approximately 83 pounds. b. Removing Contents. Perform all the steps outlined below when unpacking the equipment. Caution: Be careful when uncrating, unpacking, and handling the equipment because it is easily damaged. (1)

29、Place the crate as near the operating position as is convenient. (2) Cut and fold back the metal straps. (3) Remove nails from the top of the crate. Do not attempt to pry it off because the equipment may become damaged. (4) Remove the technical manuals and the paper- board carton containing the spar

30、e parts. (5) Slit open the fiberboard carton and fold the flaps back. (6) Remove t h e protective plywood panel. (7) Grasp the carrying handles of the receiver and carefully withdraw the receiver from the fiber- board padding which is between the receiver and the fiberboard carton. Place the receive

31、r on a bench or near its final location. 4. Checking Unpacked Equipment a. Check the contents of the cartons against the master packing slip. b. Check the front panel of the receiver for damage to the knobs or to the glass windows of the meters and fre- quency indicator dial. c. Operate the control

32、knobs; examine them for loose- ness. (1) Operate the MEGACYCLE CHANGE and KILOCYCLE CHANGE knobs throughout their ranges. Rough operations or binding may indicate a damaged tuning system. (2) Do not operate the KILOCYCLE CHANGE knob past the point where a red + or -sign ap- pears on the frequency in

33、dicator. d. Remove the top and bottom dust covers by remov- ing the 16 screws (TM 115820-357-10) and lockwashers that secure the covers to the main frame. Replace the screws and lockwashers that hold the dust covers in their positions so that they are available when the dust covers are reinstalled.

34、e. Inspect the subchassis on the upper and lower decks of the receiver for loose tube shields and broken tubes. f. If the receiver is to be used in a fixed installation, remove the shields from all tubes (fig. 8 and 9), except V201 through V206, V505, and V701. g. Unless extremely dusty conditions a

35、re expected, do not replace the dust covers. h. Do not replace the dust covers if the receiver is to be installed in Cabinet, Electrical Equipment CY- 979/URR or CY-917/ URR. Securely wrap the tube shields and the dust covers. Mark the nomenclature and the serial number of the receiver from which th

36、ey were removed on the cover of the package. Store them for fu- ture use. Reinstall the tube shields and dust covers when the receivers are stored or shipped. i. See that all connectors are seated firmly and are in their respective sockets. Loose or improperly seated con- nectors are a common cause

37、of faulty operation of radio equipment. j . Remove the three fuses from the rear panel (TM 11-5820-357-10). Check to see that they are of the proper rating. Make sure that the fuses are firmly seated after replacing them. 3 Figure 1. Unpacking k. Inspect for bent or broken connectors and terminals o

38、n the rear panel. See that the special tools are placed in their holders (TM 11-5820-357-10). 1. Remove the small cover (TM 115820-357-10) at the lower right-hand corner of the rear panel. See that the spare fuses are of the proper ratings and are in place. m. Check the contents of the box that cont

39、ains the running spares for damaged parts. n. Perform the installation and connection procedures given in paragraphs 5 and Caution: To avoid serious damage to the receiver, do not use any fuse other than the value specified. 5. Installation Requirements If the receiver is used as a part of a system,

40、 refer to the technical manual for that system. Instructions for in- stalling the receiver for fixed and mobile use are listed in a through d below. Note. The receiver is frequently used with rhombic, dou- blet, or double-doublet receiving-type antennas. For infor- mation on the rhombic and doublet

41、antennas, refer to TM 11- 666. For information on the double-doublet antenna, refer to TM 11-2629. a. Fixed tabletop Installation. When housed in cabi- net CY-917/URR or a similar well-ventilated case for fixed operation, the receiver can be placed on any sturdy bench, table, or desk. b. Fixed Cabin

42、et installation. To install the receiver in a standard cabinet, such as Cabinet, Electrical Equipment CY-1119/U. remove the top and bottom dust covers to increase ventilation. Remove one of the blank panels from the cabinet and install the receiver. Secure the front panel to the cabinet with the bol

43、ts removed from the blank panel. Insert them in the elongated holes along the vertical edges of the receiver front panel. c. Mobile, Tabletop Installation. When the receiver is housed in Cabinet, Electrical Equipment CY-979/URR for mobile operation, the cabinet must be securely bolted to a table or

44、bench. Allow enough room for ventilation, access to the connections on the back panel, and with- drawal of 4 the receiver from the cabinet for servicing. Adequate lighting facilities must be provided to permit reading the control names and positions during day and night opera- tion. d. Mobile, Cabinet, or Rack Installation. When the re- ceiver is installed in Cabinet, Electrical Equipment CY- 1216/U for mobile operation, the cabinet mu
