Hiper SR won't turn off power light.

Hi, my name is Pedro Henrique.

I have a GPS Hiper SR and i'm a problem with it.
My Hiper SR won't turn off the power light.
When it happens i can't record the points.

The normal operation is:
1 - Turn on GPS HIper SR
2 - Wait the power light turno off
3 - Press the power 3 times in a row within
2 seconds to recording.

Now, the power light stays on. Consequently i don't can record.
What is happening? Please, i need your help, for i can't fix it on my own.

Thank you!
