who told you we can adjust volume and setting to our comfort level? we were told volume is set at 3 level and cant be lowered further than that by any of us drivers. same with sensitiveity..one of our drivers called mobile eye and was told they recomend sensitivety be set at 1.5 not the 2.5 its set at now.thats all npmes doing. one driver said to write eye up every day as to loud and sensitive and if everyone did it, someone would have to address this problem .personally, i thinks the clowns in charge are to arrogant like there YRC handelers to care what we as drivers think, as only they no what safe is. at the right volume and sensitivety levels this could be a good saftey tool, now all is does is **** me of, give me a headache , and make me want to run someone over 30 minutes into the night as apposed to 8=9 hours into the night. .
