Bluetooth function incorrectly

I received yesterday my "musicman" with bluetooth funftion. first charged.
then I turned it on, followed the instructions provided for the Bluetooth Application.
my phone bluetooth provided.
The mobile phone has the MusicMan found immediately.
good has "music woman" talked to me. everything great.
everything flashes happily to himself. cell phone music turned on.

then nothing.

there was no music from the musicman. the flashing light disappeared.

Unfortunately, I have followed the flashing bluetooth function can not adjust. no matter how long you held down the "play button" (to should switch to the various features included one play short hold) it was only a continuous blue light angezeit - or halt nix. my phone has the musikman then also can no longer be found via Bluetooth.
with cable but does the musicman without further - whether docked at cell phone or laptop.
ISS but not the intention when the device with Bluetooth ordered ..

will send it back and test vor'm buy in the store a.
pity. the volume is totally OK, OK Bass also man should stand but the cubes to experience the bass :-)
apparently is a buying this product a "lucky dip" (stroke of luck)
