[Elecraft] TMp Cable and Allen Wrench Envelope

[Franz Nieberding]

Hi all,
I am a proud new owner of a K3, which was handcarried by a friend to Europe. After a week or so he sent me two little envelopes, one with a TMP cable, one with a Allen wrench. I couldn't find a hint what to do with these little parts, are they a sparepart/tool for just in case or did I miss something and they are needed to bring the nice new toy up to speed? Maybe somebody can tell me, please.
