Furuno FAX-408 manual Manual phasing, Synchronization, Reverse mode

1. OPERATION

IOC

IOC is an acronym meaning Index of Cooperation, and it is the line density standard assigned by WMO: IOC 576, high density, IOC 288, low density. To choose IOC, do the following:

1. Press the IOC key to show the IOC display.

IOC: 576

1-576 2-288

2. Press the 1 or 2 key to choose appropriate IOC.

1.9.2Manual phasing

When the FAX-408 starts recording a broadcast already in progress, or noise prevents detection of the phasing signal, a dead sector (black or white stripe) may appear on the recording. This phe- nomenon is due to phase mismatching. When this occurs, adjust recording position as shown below.

Dead sector (can be white)

To adjust phasing, use the W or X key. Press W to shift leftward; X to shift rightward. Each press shifts the recording leftward (rightward) by about 5.0 mm.

1.9.3Synchronization

If the dead sector is plotted at an angle even when the phase is properly selected, adjust the syn- chronization to display the dead sector straightly, using the SYNC control. Rotate the control coun- terclockwise if the picture is skewed leftward, or rotate it clockwise if the picture is skewed rightward.

Rotate counterclockwise

If picture is skewed leftward

(SYNC)

Rotate clockwise

If picture is skewed rightward

1.9.4Reverse mode

Most facsimile stations transmit facsimile images with black text on a white background. Some stations, however, print reversely of that format. If you want to record a facsimile in a format dif- ferent from how it is being received, do the following:

1. Press the REV/z key to display the screen shown below.

REVERSE: OFF 1-OFF 2-ON

2. Press the 1 key to turn OFF reverse or the 2 key to turn ON reverse.
