if the PA is operated in the interface Mode 0 (simple PTT controlled) AND the PA is in the 

BYPASS Mode

, Band-Filters are off, no LED indication for Filter status.

if the PA is operated in the interface Mode 1-7 AND the PA is in the 

BYPASS Mode

Band-Filter LED shows the status of the selected Filter-Bank, but Band-Filters will switch off 
when the PTT is pressed.

If the PA is in the 

BYPASS Mode

, the Antenna Tuner is bypassed too. 

good to know about automatic Mode

 

In case if you operate in the Mode 1,2,7 (see compatible Transceivers/configuration pattern). 
If you press the PTT button and you have selected a carrier modulation type, the PA will 
immediately make the appropriate filter setting. In the case of the carrierless modulation 
type SSB, the appropriate filter setting is only set after the corresponding modulation. This 
means that the filters are not set by pressing the PTT button, but only as soon as a 
modulation takes place that generates enough power for the internal VOX logic to configure 
the internal filters.
