HOW TO CHANGE THE CERAMIC FILTERS

This model is used two ceramic filters of CF1, CF3. Y ou must use same type of color marked cer amic 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.

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

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.

, select )

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