Lowrance hds12

Just installed a hds12, had it turned on for about 20 mins messing around with it. Unplugged it and noticed that it felt warm enuff to get my attention. Is this normal? This is the first time having a unit this large.

You referring to the top right corner if so that's normal.

They get pretty warm. I've got 2 of em.

They just run warm... it's basically a computer. Think about how warm a laptop gets after using it for a while.
