K2-- Auto Tuner Issue

[KM4VX]

My AT has suddenly started showing "LO PO" after displaying the SWR on all bands when the TUNE button is pressed. I have the AT set to "AUTO" and even when manually increasing the power I still get the "LO PO" display after the K2 displays the SWR. Changing antennas has no effect. Ths is K2 serial number 6255 which otherwise seems to be working fine. Welcome any ideas. Thanks.

Thank you Dave for the information.  I had accidently put the radio into "TEST" mode. I think the learning curve with this wonderful radio probably exceeds the life expectancy of many Hams, this one included.

That message says the K2 is not producing sufficient power to complete
the TUNE.
Do you have power out of the K2?  Set the ATU menu to CALP and connect a
dummy load.
If the K2 power is set at the extreme low power settings, that may not
be enough to do a TUNE.  Turn the power upto 2 watts or more and try a
TUNE again.

Thanks Don. Per Dave I must have been in the TEST mode and when I got out of the TEST mode the LO PO message disappeared.
