Pyle PSWHRP58 HRM

Does anyone have one of these? I got mine yesterday, and the instruction manual appears to be written by someone who:

1. has a very poor grasp on the English language
2. has no clue how to write a technical manual
3. wishes to add to your frustration

I follow what appears to be the instructions, and either it does not switch the HRM on, so does not collect data, or I can't get it to switch the HRM band on.

I never seem to get to the same menu in the same way.

Is there anyone out there that can teach me this in plain English? If so, I would be very grateful.

Many thanks,

Kat
