For devices manufactured by Datecs such as the HiLite, HiPro, HiFive or HiPlus, you should look at the serial number. If the 6th number starting from the right is a 9, the device is a development unit, and therefore not suitable for live customers.
For devices manufactured by PAX, such as the A920 or the A80, a symbol stating that the device is in DEBUG only is displayed in the screen. It does so above any application and then, the device is a development unit, and therefore not suitable for live customers.
For devices manufactured by Telpo, such as the TPS900, it’s very clear: if the device hardware is a light blue colour, the device is a development unit and therefore not suitable for live customers.
