Operation of Parallel Index Lines 
 
◎  Parallel index lines rotate in the same direction as you turn the [EBL] control.     
(①,  ②) 
◎  The intervals of parallel index lines narrow when you turn the [VRM] control counterclockwise (③), 
and widen when you turn the [VRM] control clockwise (④).

◎ When [RADAR MENU] key is pressed, the parallel index line menu closes and the parallel index 
lines are fixed. 
 
  During the operation of parallel index lines, pressing the [EBL1] control or [EBL2] control prevents 
operating in rotation directions.    Pressing the [VRM1] control or [VRM2] control prevents 
operation at parallel index line intervals.
