HOW TO CHANGE THE CERAMIC FILTERS
This model is used two ceramic filters of CF1, CF3. You must use same type of color marked ceramic filters in order to meet same specifications. Therefore, the ceramic filter must change two pieces together since it's supply two pieces in one package as a spare parts.

· ELECTRICAL PARTS LIST (ICF-S79V)
NOTE: · Due to standardization, replacements in the parts list may be different from the parts specified in the diagrams or the components used on the set. · -XX and -X mean standardized parts, so they may have some difference from the original one. · RESISTORS All resistors are in ohms. METAL: Metal-film resistor. METAL OXIDE: Metal oxide-film resistor. F: nonflammable · Items marked "*" are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items. · SEMICONDUCTORS In each case, u: µ, for example: uA. . : µA. . uPA. . : µPA. . uPB. . : µPB. . uPC. . : µPC. . uPD. . : µPD. . · CAPACITORS uF: µF · COILS uH: µH Remark Ref.

ICF-S79/S79L/S79V Printing Method for Large Sized Documents Such As Circuit Diagrams
Printing the page that exceeds A4-size two pages (or letter size) is possible by specifying the print range. (Acrobat Reader Version 4.0 or later) 1. The enlarged print is made, if a smaller range than A4 size is specified and the A4 size is selected as a print paper. 2. Almost real sized print is made, if the range is specified, meeting the print paper size. 3. The reduced print is made, if a larger range than the print paper size is specified. Printing by Specifying a Range In printing out the drawings such as a schematic diagram and a printed wiring board larger than the printed paper size, they can be printed by specifying the range. (Acrobat Reader Version 4.0 or later) 1. Display the page to be printed. 2. From the File menu, select [Page Setup] and set the paper size. 3. From the Command bar, select [Graphic Select Tool]. (Keep pressing T , select )
4. Dragging the cursor, enclose the range on the page to be printed. 5. From the File menu, select [Print] and make sure that the [Selected Graphic] is already checked. Also, if [Fit to page] is checked, the selected range is enlarged or reduced (and rotated as necessary) meeting the paper size.

!
6. To cancel the printed range, click an arbitrary position on the screen.
