[Elecraft] my first Hi Current warning with K2

[dw]

Just want to make sure I'm running safe.
I cranked up the power full-tilt for a qso on 20m this morning.
On xmit the K2 displayed the Hi-Current warning.
CAL CUR is set at 3.50

Is there anything I should be concerned about here?
I understand there is a current limit circuit, but should I be
changing/fixing something?
