This is a feature. :-)
Basically, this is so that you can connect a straight key and a paddle
to the keyer jack at the same time, by connecting both the dit and dah
lines to ground through two diodes, without any need for settings.
This is documented in the manual.

Greetings from Down Under.
With the help and encouragement of the NZ K2 guru Ron, ZL1TW, I have
finally
got on the air with K2 Nr 3029. Getting back on air after 40 years I
decided to learn iambic keying so have used my K2 in test mode often
for
practise. I find that on some occasions when I have closed both
paddles at
"exactly" the same time and held them squeezed I get a steady tone
rather
than alternating dots and dashes.
I can repeat this in operating mode and have confirmed that power is
being
delivered into a dummy load like if a straight key was held down.
Needless
to say it does not happen very often and is an operator error which I
correct, but wondered if others had experienced this too? I have
found
that by pointing both index fingers at the paddles, one on either side
then
aiming to push them together simultaneously is a way of effecting this
and
even then it will take maybe 10 or so tries to make it happen. (BTW
this is
not how I send ;-))
My K2 has firmware 2.03d 1.07. has the Temp-compensation PLL mod
fitted
but not the Keying bandwidth mod. Installed are KNB2, KAF2 and KAT2.
InP
= PDLn, Iab = b and the keyer is set to 15wpm.
Regards
73s, Nigel ZL2DF
