power tap SL 2.4 serial number location?

[Bleve]

Just a quicky... part of sending my SL 2.4 back is filling out a warranty form, and it wants the serial number. Can anyone here tell me where that is? It doesn't appear on the computer or the hub anywhere that I can see (without removing the cassette, which is one of the reasons it's being sent back ....).

thanks

OTTOMH, inside the battery cap or it is engraved on the flange somewhere.

I pulled it to bits yesterday and no serial No. that I could find on the hub or inside the battery cover. No matter, Trek will take it back anyway.
