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.
Connecting Power
Plug the power lead into the round 4 pin socket on the panel on the right side of the C-Fax.
The other end of the lead is connected to the power source, red wire to positive, black wire
to negative. The C-Fax can operate on a direct current (DC) voltage of from 12 to 15 volts
only.
Caution!
THE C-FAX MUST NOT BE CONNECTED DIRECTLY TO A 24V
SUPPLY. To run it on 24V DC a voltage reducer must be used.
The power lead from the C-Fax must not be connected directly to the
mains power supply (110V or 230V AC). For use with the mains
supply a suitable power supply must be used which can supply 12V
DC at 2 amps.
Connecting an Aerial (for an internal receiver)
The aerial lead plugs into the BNC socket on the side panel. At the other end the center
conductor of the coaxial cable should be connected to an outside wire aerial. This should
consist of a length of wire approximately 10 metres long (30 feet). The wire should run
horizontally and be supported at each end by insulators, with a lead taken from one end to
the C-Fax. The aerial is not critical, try any existing high frequency aerial first.
Caution!
Never connect the C-Fax to an aerial used by a radio transmitter.
Severe damage could occur to the receiver in the C-Fax.
The outside shield on the end of the aerial cable can be connected to an earth, such as the
hull of a metal boat or a metal rod driven into the ground as close as practical to the C-Fax.
This earthing is not absolutely necessary but can be of help in reducing interference on the
printed pictures.
