Your device is shipped charged in an 'Off' state. Power the device on by sitting it on the charger. Remove 5 seconds after the white light appears. The blue light will blink when the device is on and ready to go.
If you need to power cycle your device, you can locate the on/off button to the right of the Puulse logo. You will need to press firmly. You should feel a faint click. We suggest you avoid using a fingernail as this could tear the silicone around the button.
