Step 2: Next find a suitable location for your Hotspot to be positioned, to provide the best coverage we
recommend placing it near a window just out of direct sunlight. You’ll need to be near a mains power
source too.
Please check "Ideal Hotspot Placement" Guide : https://github.com/NebraLtd/Helium-
Guides/blob/main/docs/handy-guides/hotspot-ideal-location.md
Step 3: Assemble the appropriate adapter for country onto the universal power supply, plug into mains
power and insert power cable into the hotspot.

Step 5: When the hotspot is powered up, the lower orange LED will be on. It will take up to 5 minutes to
configure after the first boot.
This process may take slightly longer as it’ll also perform firmware updates as soon as it gets a connection
to the internet. Once it's done you can see the Green light led is turned on.
