ISC-027BW does not connect

A newly purchased ISC-027BW does not connect.

Locations services enabled
Bluetooth on iPhone is on
iPhone is connected to 2.4G wifi network and is in the signal range

when I connect ISC-027BW to power, both Status and WiFi lights start blinking fast

When I try to connect through wifi or through bluetooth, after a while there is a message “no device found”
