Narrative:

The first officer arrived late thinking he had three days off instead of two. I did his duties in an effort to leave on time. During preflight I saw parking brake pressure was low but usable. The first officer arrived and we started boarding. We did the originating checklist checking the things I had completed before his arrival. On the before start I saw the parking brake pressure was 1400psi or so. I grabbed the pump handle and as I left the cockpit asked the first officer to make sure the doors were down. I had to work down stream of the boarding passenger with about seven minutes before our wheels up time. I pumped and got a thumbs up from the first officer. I returned to the cockpit and departed. On gear retraction got 3 red and a yellow handle. The checklist said any red call company. Selcal didn't work and relayed through operations. Company called and asked us to check the door above the first officer. He failed to close it when he dropped the gear doors to allow me to recharge the parking brake press. I should have known better. This happened to me in the early 1990s. The door is out of easy view of both pilots but that can't be changed. Perhaps a note on the emergency checklist covering three red on gear retraction.
