2.2 Manually Starting, Stopping Receiving
2.2.1 Manually starting receiving
This section shows you to manually receive a facsimile broadcast. For example,
you may want to receive a facsimile broadcast already in progress or receive
from a facsimile station that does not use start and stop signals. Further, you
may wish to stop reception to receive an image from a different station.
To manually receive a facsimile, you will first need to set a channel, referring to
paragraph 2.1. Then, do the following:
1. At the standby display, press the WX FAX soft key.
2. Press the RCV WX FAX soft key.
3. Press the START RX soft key.
The options shown are IOC (Index of Cooperation)/speed.

4. Rotate the [ENTER] knob to choose the correct combination of IOC and
speed of the facsimile transmitting station. IOC is the line density standard
assigned by WMO: IOC 576, high density, IOC 288, low density. Speed is the
rotation speed of the drum (on which the original image is fitted) at the
facsimile transmitter: 60, 90 ,120, 180 or 240 rpm.
5. Press the ENTER soft key.
6. Press the RETURN soft key.
Then, the FAX-30 will receive the current broadcast from the station selected.
Facsimile images are received line by line, taking 30-40 minutes to receive
depending on the size of the image and drum rotation speed at the facsimile
station. After a facsimile image is received it is compressed and stored in the
image memory and then posted on the “Thumbnails of received images” screen
(see paragraph 2.4). This process takes 3-5 minutes. You can see the image
being received by pressing the WX FAX soft key on the fax standby display and
then hitting the RCV WX FAX soft key.
