That sucks
After the next attempt to make power supply directly, instead of the accumulator, my iriver has died
As it was found out later, because of a glitch of the voltage switch which I what for have left, my self-made DC-DC converter has given out a voltage of 10 Volt! My iriver any more has not sustained
Now by pressing on "Play" the voltage on the battery goes down on 0.02V, but player not starts or anything
Now I save money on Rapsody RSH-100. Because replacement of a motherboard will cost to me as much. And iriver I shall postpone till the best times...
