Phase mismatch

When the FAX-30 starts receiving a broadcast already in progress, or noise
prevents detection of the phasing signal, the image may be divided into two
parts by a thick black (or white) stripe called a dead sector. This phenomenon is
due to phase mismatching. When this occurs, correct phase mismatching, after
the facsimile has been received.
1. With a facsimile image displayed, click PHASE.
2. Read the scale to find the center of the dead sector and enter it in the phase
entry window. For example, if dead sector is centered at "15" on the scale, as
in the illustration at the top of the page, enter "15". The setting range is 00 to
40.
3. Click OK and then click "<back" or Back button to return to the top menu.
