Narrative:

On the ground; I set up the pressurization control panel. This was an older model aircraft with the old analog panel. I inadvertently set '11;300' in the landing elevation window but correctly set '01130' in the secondary window. We ran the before push checklist and did not catch my mistake. On climb out through approximately 30;000 ft; we got the cabin altitude horn and light. We accomplished the memory items and I asked ATC for a lower altitude.as I was accomplishing the qrc; we noticed that the aircraft was holding the cabin altitude steady at 10'000 ft. While continuing with the qrc; I noticed my error of placing '11;300' in the landing elevation window. I set the correct altitude in the window and the cabin altitude returned to normal. After finishing the qrc; reviewing the QRH; and discussing the situation; we advised ATC we could climb back to altitude and continued without any further incident.as we have fewer and fewer older model aircraft and analog pressurization controllers; I need to ensure I double check that everything is set up properly; especially in the altitude window. Even though we both looked at the controller during the checklist; our expectation bias didn't catch the error because the number displayed in very small print was mostly correct; except for the extra zero at the end on the readout.

Title: Older model transport aircraft flight crew reported the cabin depressurized after they departed with destination field elevation set to 11;300 ft instead of the proper 1;130 ft. First Officer commented the older analog style panel is more difficult to use.
