When an optional RF µTuning Kit is connected, press-
ing this button will engage the µ-Tuning filter. The
µTuning Kit provides much better RF selectivity than
any other RF filter in the Amateur industry, yielding
outstanding protection from high RF levels not far re-

When the LED in the A/B button is turned "off"
In this case, the [ CLAR ( VFO-B )] knob is used for Clarifier tuning, as well as Up/Down selection of the Amateur

Clarifier Operation
When the [ CLAR/GRP ] button is pressed briefly, the
imbedded LED in the button will glow red, and the

To reset the Clarifier frequency offset to "0", press the
