[Elecraft] K3: OK to Use Mono Adapter Jack on “Key” port?

[B Deuby]

I want to experiment using my UR5CDX CT 755 single paddle keyer as a cootie. I understand that this can be done by fitting a mono adapter jack on the end of the (stereo) keyer cable jack and plugging it into the K3 "Key" port. I seem to recall reading a caution concerning the use of mono and stereo jacks somewhere in the K3 documentation - but now I can't find it. Is there any reason I couldn't plug the keyer into the "Key" port with a mono adapter jack?

Thanks, Brian K8GRR
