Narrative:
While at FL340 the cabin altitude warning light illuminated; an emergency was declared and we began a descent to 12;000 ft. We put on our oxygen masks;established communication and backed it up with the rapid decompression emergency checklist. Cabin pressurization was restored at 12;000 and we continued to our destination. After pressurization was restored we no longer needed emergency handling.
