4.6.7.4  Operation in [Equiangular] mode 
The index lines of the group that is selected in [Group] combo box are operated in [Equiangular] mode. 
 
[Operating the [EBL] dial] 
By pressing the [EBL] dial, the "Group reference line (PI Bearing)" and the "Group measurement line" 
can be set. 
Whenever the [EBL] dial is pressed, the "Group reference line (PI Bearing)"  and the "Group 
measurement line" are selected alternately. 
 
A measurement line can be set across the reference line. (When a measurement line is set across 
the reference line by rotating the dial in the minus direction, the measured bearing data changes 
as 0°→359.9°.) 
When the reference line is set by using the EBL dial, the value of the measured bearing data is 
maintained and the measurement line follows concurrently. 
 
[Operation the [VRM] dial] 
In [Equiangular] mode, the [VRM] dial is disabled.
