path, both channels output optical power. You can only view or set the
parameters for the primary optical output, for example, the high power
output for <Both (master:2)>.
The LED beside the primary optical output is lit constantly, while the LED
beside the secondary optical output flashes. For example, if you select
<Both (master:2)> as the regulated path, the LED beside Output 2, the
High Power Output, is lit constantly and the LED beside Output 1, the Low
SSE optical output, flashes.
