4.6.4  Setting parallel index lines individually 
(Individual mode) 
By setting the operation mode to [Individual], the bearing and the interval of parallel index lines can be 
set individually. 
 
 
1  Select [Individual] from the [Mode] combo box. 
2  Select a parallel index line (1 to 8) to be set from the [Index Line] combo box

When the dial is turned clockwise, the bearing is adjusted in the plus direction, and when 
the dial is turned counterclockwise, the bearing is adjusted in the minus direction. 
The set value is displayed in the input box.

The input range is the PPI radius when PPI is used as the centre for the lines and double the PPI 
radius when the PPI is not used as the centre.

the dial is turned clockwise, the interval value increases and if
