Narrative:

While cleared into position to hold on runway 28R at pit, tower said there would be a 'short delay' in position. My first officer was new to the aircraft and I was the instructor pilot giving him his IOE. This was leg #3 of his actual flying. After tower cleared us into position, the first officer must have mistakenly switched to departure control. We were not aware of this error until I noticed an ACARS message from company to check frequency 128.3. I immediately realized we were on departure control and switched to tower of 128.3. I apologized to tower and told him we had mistakenly been on departure. There was no conflict of traffic and no gars to our knowledge. Takeoff was then normal. Upon landing again 2 hours later at pit, I called the tower supervisor. He said there was no conflict and he appreciated me calling. Callback conversation with reporter revealed the following information: the reporter flies the B-737-200 for a major united states air carrier. The pit ATCT had no traffic problems because of this incident.
