Narrative:

On departure; a noticeable squealing noise started to generate from my clear view window as we climbed through 5;000 ft. As I investigated the noise I discovered that my headset cord was caught in the upper left corner of the window (I had opened the window at the gate to speak to the ramper; because he was having trouble getting a headset to work). The noise was getting louder the higher we climbed; so at about 9;000 ft; I asked ATC if we could level off for a few minutes to sort out the problem. Consulted the QRH and decided I would attempt to open the window enough to clear the headset cord. I asked to descend to 5;000 ft. We ran the pressurization manually to 5;000 ft cabin altitude and slowed to maneuvering speed. I opened the window enough to clear the cord; closed the window; returned the pressurization system to auto and continued on to destination.
