A flashing yellow light on the LED ring means that the user interface is not accessible on the scanner. The scanner is booting up which causes it to blink when you turn it on, just as a laptop does when you turn it on and wait for the desktop to appear.
However, if several minutes pass and the scanner keeps blinking and the hotspot is not appearing on the iPad, there is a change the computer inside the scanner (known as a NUC) is struggling to start. The reasons for this can vary, so please follow each of there steps in order to identify and further correct the issue.
Please note that it is important that each step is followed in order and done according to the instructions.
Restart the scanner. Unplug the power cable from the scanner, wait 30 seconds, and then plug it back in. It is important to wait in between, as the hardware needs to reset fully. Once plugged in again, wait 2 minutes to see if the blinking stops. If not, proceed to step 2.
Open the scanner. Instructions on how to open the scanner unit can be found here. Once open, remove the power cable and the Ethernet cable that’s currently plugged into the NUC as shown in the image below.
Thereafter, plug the external power and Ethernet cable directly into the NUC where the other cables you removed used to be.
Check the lights. The light on the NUC itself should be blue, as displayed in the images below where you have an older NUC model to the left and a newer model to the right.
If the above light is blue or yellow and the hotspot is not showing, hold in the power button until the unit is turned off. The power button on the older NUC model is shown by the arrow in the left image. Once the unit is turned off, wait 30 seconds until you turn it on again. Thereafter, wait an additional 2 minutes to see if the hotspot appears on the iPad.
If the above light is red or orange and the unit will not start, proceed to step 5.
If the light in step 3 is still blue or yellow and the hotspot is not showing on your iPad, check if the Ethernet cable is showing the lights displayed in the image below.
