Found this on the site as well.

To set alarm on these units pull the small knob out. This will turn the marker light on. Rotate the small knob until the marker light is at the desired depth setting. If desired the knob can be pushed in to turn the marker light off. This does not turn the alarm off, just the marker light. If any echoes appear between the marker light setting and six feet, the alarm will sound. Adjust the large, inner knob for the desired volume.

I guess you might try em and see if either of these is what your model does.

thanks MAXIMUS after thinking about it , and the gears are starting to turn slow, I think your first thought was wright, seems like that it to me, after I go to the lake ill know for sure. thanks for jogging the old memory

I was looking at mine on my boat and it says pull for supressor. However, mine is on an older ranger and you dont have to pull it to use it. It works the same in or pulled out. It may just be because it only 27 years old lol. The bigger knob controls the depth range and on off. Click over once to turn on, then click again to change to another depth range. Hope you figure it out.
