Take of your right shoe.
Pull up the inner sole.
There is a thin metal string.
Pull the thin metal string from the shoe.
Hold it between your forefinger and thumb nail.
Run your thumbnail down the string at about three finger widths per second. It will vibrate.
You should hear a recording with instructions.
Use your smartphone to record it and play back at volume if you need to.
Good luck.
