Another MM Q ~ Lawn Dart

[jayjay283]

As the title says I bought one of those $29 skate ramps from Toys R US, put a few bricks under the back for more air and was doing some 6-10ft jumps with my 8T till I lawn darted.. hard The MM shut off and when I turned it back on it had real soft tones. Nothing came loose or broke just the MM alert volumes are about 1/3 as loud when turning it on or the intermittent beeps. Seemed to run fine after that just low volumes. Did I just jar the speaker ?Anyone have this issue ?
