Backlighting on Target instruments

[Moët]

Just a quick question about a couple of NASA instruments I have; I've got a new Target 2 depth sounder which has a backlight and an older original Target log (with the smaller display). Does this model also have a backlight and how is it turned on if so? And is this NASA the space people?

Thanks in advance.

Downloads of manuals from their website should answer your questions

The older models had a separate orange lead for the backlight which you could connect to an external switch.
Newer models just have two wires and lighting controlled by pressing SET button.
