What's the green thing by the headphone jack?

A very common modification, especially by the Navy, was to add a jack
there to monitor the diode load voltage, this makes their regular
maintenance much much easier. NAVSHIPS-0967-063-2140 documents this.

The NAVSHIPS document states that a Dymo label should be affixed by the
jack.

Related to your other comment, I think that the one on the E-place has
been repainted.

My yellow striper came with the decades-old Dymo stickers still
attached. I swear the glues in modern Dymo labels aren't as good.
