Speed
The picture advance speed determines how

vance speed will contract it.

SOUNDER SETUP OPTIONS.
2. Select PICTURE ADVANCE, and press
the soft key EDIT to open the picture ad-
vance window.

The fractions in the window denote num-
ber of scan lines produced per transmis-
sion. For example, 1/8 means one scan

sions. STOP freezes the display and it is
convenient for observing an echo.
