Troubleshooting
Problem: what do I do if I try to disconnect via the green arrow but keep getting “The
device ‘Generic Volume’ cannot be stopped now. Try stopping the device again
later.”
Answer: shut off any program that might be accessing data on the AV300, including
Windows
®
Explorer. If this does not work, shut down all programs, wait 20 seconds, then
try the green arrow again. If this does not work, you should shut down the computer and
disconnect the USB cable once the computer is off.
14.2 Charging and Power issues
You do not need to fully discharge the batteries before recharging them. Empty batteries
will take 4 hours to charge without usage. More if you use the unit while charging it.
Problem: a full battery charge does not last as long as the specications suggest.
Answer: the specications are under the condition that the screen backlight goes off
after 30 seconds (for MP3 music) and the user does not access the machine, it just sits
and plays. If you get signicantly less time from a full charge, call our technical support
hot-line.
14.3 AV300 locks up (freezes operation) or Stops
Problem: the AV300 locks-up. None of the buttons work.
Solution: if the lock buttons is set, none of the buttons respond. Hold down the top
function button for three seconds to turn off the lock buttons function. A freeze up could
also be caused by electrostatic phenomena. That is, static electricity has temporarily
knocked out the AV300. Hold down on the STOP/OFF Ó button for 15 seconds and the
AV300 will shut off. Restart it normally now.
14.4 The Computer locks-up (freezes operation) or Stops
Problem: the computer locks-up.
Answer: most likely because you did not use the green ‘safely remove hardware’ icon in
the system tray in order to remove the AV300 from your computer.
14.5 File issues, corrupted data, formatting, and partitioning
Problem: on the AV300, I nd new le names and folder names that I never created or
they have strange gibberish names.
Answer: most likely, the AV300’s le allocation table (FAT) has been corrupted. This could
have been due to the AV300 shutting down (due to low battery power) while reading
or writing to your computer via the USB connection. To x a corrupted FAT problem, you
should use the Error Checking utility or the Check Disk utility explained at the end of this
section. Attention: Windows and Macintosh often write extra les to the hard disk such as
nder.def or System volume info. These are normal and will not harm the AV300.
