CRJ700 FLT CREW HAS ALTDEV DURING DEP FROM MWH.

Narrative

WE WERE DOING TRAINING IN OUR NEW CRJ-700; FLYING FROM CITY TO CITY SHOWING OUR FIRST CRJ TO OUR AIRLINE'S STATIONS. WE WERE CLRED VIA CLRNC DELIVERY AT MWH TO 10000 FT TO EXPECT 11000 FT. ON CLBOUT I ENGAGED THE AUTOPLT AND WE WERE GIVEN A TURN OF 180 DEGS OFF RWY HEADING. AS I WAS CLBING OUT OF ABOUT 5000 FT MSL WITH AUTOPLT ON; I REACHED FOR THE SPD KNOB TO INCREASE MY CLB SPD TO 250 KTS FROM THE 200 KTS I HAD IN THE TURN. I ACCIDENTALLY ADJUSTED THE ALT KNOB. I NOTICED THIS AS THE AIRCRAFT WASN'T ACCELERATING. I LOOKED AT THE ALT ALERTER AND IT WAS NOW SET AT 11300 FT; SO I RESET IT TO 11000 FT. THE PNF WAS OUT OF THE LOOP TALKING TO COMPANY WITH OUR OUT AND OFF TIMES. WE WERE HANDED OFF TO ZSE AND REPORTED CLBING TO 11000 FT. ATC QUESTIONED OUR ALT AS 11000 FT? NO OTHER COMMENTS WERE MADE. I DON'T KNOW IF WE WERE EVER CLRED TO 11000 FT. ONE MAJOR PROB IS THE ALT; SPD AND HDG KNOBS FEEL VERY SIMILAR. THERE ARE SOME MINOR DIFFERENCES ON THE TEXTURE OF THE KNOB BUT NOT ENOUGH FOR A PLT TO NOTICE UNDER FLIGHT CONDITIONS.
