The write on the site : 5. I'm sure my THUMP is fully charged, so why doesn't it play music?
Make sure the volume is not set too low to hear.
Make sure there are song files stored on THUMP. Connect THUMP to your computer and open the folder that shows the contents of the THUMP memory
Make sure you have the correct music file formats loaded into the THUMP memory. Currently, THUMP plays MP3, WMA and WAV file formats. No other music file formats are supported at this time.
Make sure the WMA music files you are trying to play are not protected by DRM. (See below for more information on DRM.) If the song files are protected by DRM, you need to download the DRM Enabled Utility found at www.oakley.com/thump.
6. Why can't I get a full six hours of song play time out of THUMP?
Many things affect play time, including the volume level, file compression and music file format. Also, lithium ion polymer batteries gradually lose their charge while not in use. These batteries are also susceptible to temperature.
Even though they represent the best technology available, lithium ion batteries do not perform best in high heat.
7. Is it best to completely drain the THUMP battery before recharging?
It makes no difference. Lithium ion batteries have no "memory effect" like older technologies such as nickel cadmium, so you can charge them at any time - even when they are not fully discharged.
