ATU Operation
1. Rotate the [RF PWR] knob fully clockwise (to the right).
2. Use the Main Tuning Dial knob to set the radio to desired operating frequency
within the Amateur band.
3. Press the [TUNE] button momentarily to place the ATU in the transmit line (no
adjustment/tuning will occur yet). “TUNER” icon will appear in the display.
Quick Point: The momentary press of the [TUNE] button will turn the tuner on,
and the microprocessor will automatically select the tuning point closest to the
current operating frequency.

4. Press and hold in the [TUNE] button for two seconds to begin automatic tuning.
The transmitter will be engaged, and the “TUNER” icon will blink while tuning is
in progress. When the optimum tuning point has been reached, the radio will
return to receive, and the “TUNER” icon will again glow steadily (instead of
blinking).

return to receive, and the “TUNER” icon will again glow steadily (instead of
blinking).
5. While tuning around the band using the Main Tuning Dial knob, you will observe
that the “TUNER” icon blinks momentarily every 10 kHz. This momentary
blinking indicates that a new tuning window has been entered. If you want to save
tuning data associated with this 10 kHz window, repeat step 4 (above) for each
such window. On bands like 1.8 MHz where the impedance may change rapidly,
the storage of a number of tuning points is recommended.

6. To disconnect the ATU from the transmit line, press the [TUNE] button
momentarily. The “TUNER” icon will turn off, confirming that the ATU has been
turned off. In the “Off” mode, the transceiver will be directly connected to the
coaxial cable connected to your antenna, and will operate based on whatever
impedance is present at the station end of the coax.

Advice:
The ATU is connected both to the transmitter and the receiver, and its natural RF
selectivity has a beneficial effect in rejecting out-of-band energy during reception.
Accordingly, we recommend that the ATU be left “On” at all times.
Quick Point:
As shipped from the factory, only one ATU alignment point is saved on each
Amateur band. This was memorized during the final alignment and performance
