Force Manual Xmit?

[icepick]

I'm doing some setup, and wondering if there is a way to force the ALP to transmit in protection mode without an external stimulus (e.g., without a legitimate LIDAR source). My PL2 is 200 miles away in self storage, and I'd really like to "see" the IR transmitted through a couple of different media that I'm thinking of using as a disguise.

Absent a manual option, is there a transmit sequence as part of start-up while the heads are being registered/checked?

Thanks for any help!
