As I approach a user marked school zone in my area, the unit alerts at 600+ yards and begins to count down distance. When the marked location is reached, the unit gives a four tone sound then resumes normal operation.
OK, what happens sometimes, (same location mentioned above), the unit will alert and begin the normal yardage countdown, then when the marked location is reached, instead of the four tone sound and resume, the unit starts to count back up yardage indefinately until the power is cycled. Nothing is different about my direction of travel when this occurs. (In other words, I don't turn off my direction of travel). And this doesn't happen everytime, just twice since my purchase and I pass through at least twice a day.
Normal operation w/ a change in direction:
I have another location where I make a turn after the unit alerts, but before the marked location is reached and after I turn the unit will count back up to the 600 yard radius then sound a different tone and resume normal operation.
Has anyone w/ one of these experienced scenario #2? My unit software is up to date. Thanks.
