Beacons

4G or Wi-Fi hotspot

With 4G: switch the master on. Nothing to set up: it shows on the Chain tab once it is online.
Without 4G, a scanner can be the master over a Wi-Fi hotspot. Switch the hotspot on.
Switch the scanner on, or off and on again, and stand next to it. It can be set up for 10 minutes.
In your phone's Wi-Fi settings, join Beacons- followed by the last four characters on the unit's label, for example Beacons-D7FC.
Its set-up page opens by itself. Pick the hotspot and type its password, then come back to this page.
On Chrome on Android you can also do it from here: tap Find the unit.

To reset a Wi-Fi hotspot master: switch it on and off three times in a row, each time for less than 10 seconds.
