Narrative:

Departed runway 26R at ont on prado 6 departure. Switched to socal departure after takeoff. Socal acknowledged us and said 'cleared prado 6; climb and maintain 7000 ft.' switched to next socal frequency and controller asked us if we knew there was a 4000 ft altitude restr 6 DME from pdz VOR. We confirmed we knew about it and he said there was no problem on what we did; but to be aware of it the next time. We felt that clearance from the previous controller to 7000 ft negated that 4000 ft restr. Further on the departure SID we were cleared to 14000 ft and asked to comply with the altitude restrs on the SID. We did that and felt the first departure controller should have given us the 'comply with SID altitude restrs' like the third departure controller did. Even though ATC said there was no problem; we feel the initial climb clearance to 7000 ft was confusing if they wanted us to comply with altitude restr on the SID.

Title: A300 CREW MISUNDERSTANDS CLB CLRNC FROM SCT ON PRADO 6 AT ONT.

Narrative: DEPARTED RWY 26R AT ONT ON PRADO 6 DEP. SWITCHED TO SOCAL DEP AFTER TKOF. SOCAL ACKNOWLEDGED US AND SAID 'CLRED PRADO 6; CLB AND MAINTAIN 7000 FT.' SWITCHED TO NEXT SOCAL FREQ AND CTLR ASKED US IF WE KNEW THERE WAS A 4000 FT ALT RESTR 6 DME FROM PDZ VOR. WE CONFIRMED WE KNEW ABOUT IT AND HE SAID THERE WAS NO PROB ON WHAT WE DID; BUT TO BE AWARE OF IT THE NEXT TIME. WE FELT THAT CLRNC FROM THE PREVIOUS CTLR TO 7000 FT NEGATED THAT 4000 FT RESTR. FURTHER ON THE DEP SID WE WERE CLRED TO 14000 FT AND ASKED TO COMPLY WITH THE ALT RESTRS ON THE SID. WE DID THAT AND FELT THE FIRST DEP CTLR SHOULD HAVE GIVEN US THE 'COMPLY WITH SID ALT RESTRS' LIKE THE THIRD DEP CTLR DID. EVEN THOUGH ATC SAID THERE WAS NO PROB; WE FEEL THE INITIAL CLB CLRNC TO 7000 FT WAS CONFUSING IF THEY WANTED US TO COMPLY WITH ALT RESTR ON THE SID.
