1730–Series Operating Instructions
2–6
18 DOWN
Decrements the line count (when enabled). Holding the DOWN push button in
decrements faster.
Holding either button down until the count passes the beginning or end of the
field causes the count to shift to the other field.
(When LINE SELECT is enabled, holding in both the UP and DOWN push
buttons returns the line count to Field 1, Line 19.)
19 STORE
Enables the storage of front–panel settings, including line number, in four
different memory locations. To Store a front–panel setup, the STORE switch is
pushed and then one of the four RECALL SETUP switches is pushed. When
STORE is pushed, all front–panel lights cycle off and on (approximately 15
times) to indicate that the front–panel, as it is currently set up, can be Stored. If
the current selection is not the desired setup, pushing any front–panel button,
except a RECALL SETUP, will cancel the STORE mode. If one of the
RECALL SETUP switches is pushed while STORE is active, the current
front–panel setup will be stored in the selected RECALL position. CAL cannot
be Stored.
When a Store operation is performed on the 1735, the selected standard (50 Hz,
60 Hz, or AUTO) is stored.
20 RECALL SETUP (1–2–3–4)
Recalls from memory, or causes the storage in memory of a (1–2–3–4) front–
panel setting. Each of the four switches operates with a memory location and the
STORE push–button switch.
A special feature in the 1735 allows the operator to use the Store and Recall
function in the normal manner, or to select from three operating modes by
holding the RECALL switches. The 50 Hz (PAL) standard of operation is
selected by holding the Recall Setup 1 button and 60 Hz is selected with the
Recall Setup 2 button. AUTO, which provides automatic switching between the
two standards, is selected with the Recall Setup 3 button. In non–line select
modes of operation, holding the Recall Setup 4 button will display the status of
the current standard.
If 50 Hz or 60 Hz operation has been Stored as a setup, it will be recalled by
pushing a RECALL switch. If the AUTO mode of operation is Recalled, and a
change in input signal standard has occurred, the 1735 will recall the correct
Recall Setup
