Note 1 : For example, taking the PC98 table on the previous page as an example, as the relative addresses 01,
02, and 03 contain data 02, 48, and 30, the PC98 horizontal frequency setting value is 24.83 kHz.
Note 2 : FF when the method is not limited.
Note 3 : FF when the polarity is not limited.
Note 4 : If the relative address data is:
65 : Indicates 6-5 conversion
A7 : Indicates 10-7 conversion.

Explanation : • Directly changes the horizontal frequency of the model data table used for the VS board cur-
rently.
• Input the frequency using 6-digit decimal numbers. When data input is omitted, the horizontal
frequency on the current model data table is displayed.
• Refer to "Using Methods of HFQ, VFQ, VLN" described later on the using methods.
(Example)
Although numbers outside the horizontal frequency specification range (24.0 kHz to 35.0 kHz)
range of this board can be input, they cannot be used as preset data.
