The CLAR button and CLAR/VFO-B knob are used to offset the receive frequency, the transmit frequency, or both,
from their settings on the VFO-A frequency. Four small numbers on the TFT Display show the current Clarifier offset.
The Clarifier controls on the FT-991 are designed to allow setting a preset offset (up to ±9.99 kHz) without actually re-
tuning, and then to activate it via the Clarifier CLAR button. This feature is ideal for following a drifting station, or for
setting the small frequency offsets sometimes utilized in DX "Split" work.
Here is the technique for utilizing the Clarifier:
1. Press the CLAR button. The "RX" notation will ap-
pear in the TFT Display, and the programmed offset
will be applied to the receive frequency.
2. Rotation of the CLAR/VFO-B knob will allow you
to modify your initial offset on the fly. Offsets of up
to ±9.99 kHz may be set using the Clarifier.
To cancel Clarifier operation, press the CLAR button.
The "RX" notation will disappear from the display.

Turning the Clarifier off merely cancels the applica-
tion of the programmed offset from the receive and/or
the transmit frequencies. To clear the Clarifier offset,
and reset it to "zero," press and hold the CLAR button.
The programmed offset is displayed in the small multi-
channel window of the frequency display.
