Page 3: Introduction
Introduction The C-Fax radio facsimile receiver has been designed as an easy to use, reasonably priced unit with low operating costs. The materials and finishes used ensure durability and long life, and the small size enables fitting in areas where space is at a premium. The C-Fax uses standard fax paper as used in telephone fax machines. -
Page 4: Mounting
Mounting the C-Fax The C-Fax may be left free standing or wall mounted on the supplied bracket. To fix the C-Fax to a wall, remove the mounting bracket from the rear of the C-Fax by taking out the two screws holding it at the bottom. Screw the bracket to the wall, slide the C-Fax back onto the bracket and replace the two bottom screws. -
Page 5: Connecting An External Receiver
Using an External Receiver An external receiver may be used with the C-Fax and is required if your model has no internal receiver. It must be a crystal controlled or synthesised SSB (single side band) type, with LSB (lower side band) mode. Connection should be made from either the speaker output or line level output of the external receiver to the audio socket on the side panel of the C-Fax. -
Page 6: Loading Paper
Loading Paper The C-Fax uses standard telephone fax machine paper, 216mm wide. The recommended paper length is 30m, longer rolls may not fit. To load a roll of paper into the C-Fax, open the two catches located each side on the front. Pull the lower edge of the catch away from the C-Fax and then unhook the upper edge. -

Page 8: Using The C-Fax
Using the C-Fax Switching On Make sure power plug and aerial connections have been made and that a roll of paper is properly inserted in the C-Fax, as described on pages 4 to 7. Move the power switch (number 7 in the picture on the previous page) down. If your C-Fax has an internal receiver the channel display (9) should show the current channel number, location and frequency the C-Fax is listening to. - Page 9 picture generally takes about 15 minutes to send. Finally the stop signal is sent. This is 5 seconds of alternating tones followed by 10 seconds of a steady tone. You may turn off the audio by putting the Audio switch (1) back to the middle position. It is only required for determining the signal quality of a channel.
