Gotta beep

[riverfisher]

So I had my boat out for the first time yesterday. Start the motor up to move to another spot get up on plane go to adjust the trim and I get a quick beep when I trim up and when I bring it down. Anybody have any ideas is that a warning to top off the hydrolic fluid? Any help would be greatly appreciated!!

The motor is a 2002 Mercury 150 XR6.

Thanks
