Narrative:
Aircraft cleared to 4000 ft via ACARS before pushback. 5000 ft inadvertently set in altitude window on aircraft altitude alerter. On initial call to departure, first officer stated that we were climbing to 5000 ft. ATC came back with a 'roger.' this could probably have been prevented if we had double-checked altitude set prior to takeoff. There was no conflict.

Narrative: ACFT CLRED TO 4000 FT VIA ACARS BEFORE PUSHBACK. 5000 FT INADVERTENTLY SET IN ALT WINDOW ON ACFT ALT ALERTER. ON INITIAL CALL TO DEP, FO STATED THAT WE WERE CLBING TO 5000 FT. ATC CAME BACK WITH A 'ROGER.' THIS COULD PROBABLY HAVE BEEN PREVENTED IF WE HAD DOUBLE-CHKED ALT SET PRIOR TO TKOF. THERE WAS NO CONFLICT.
