Before placing your hotspot outside you need to check a few parts to ensure the waterproofing
Step 1: Check the bolts
You should make sure that all bolts are tight. Control all bolts at the top and the bottom manually. The medium-sized bolts should have rubber gaskets on them. The small ones don't have a gasket.
Step 2: Check the antenna connectors
Make sure that all antenna connectors are fully screwed in. They need to sit tight and the gasket should be squished. They should look as follows:
If they look like the following, you should tighten them further:
Step 3: Check the gasket of the bottom cover
You need to make sure that the gasket for the bottom cover is properly seated and not damaged
Step 4: Install the sealing string on the top cover
The seal for the top cover is not inserted when you receive the hotspot. You need to push the sealing string into the top lid and cut it to the correct length needed. The ends should connect at the bottom of the hotspot.
Step 5: Install the Ethernet gland
Make sure that the Ethernet gland is properly sealed with the fitting connector.
Step 6: Tighten the bolts of the casing
After closing the lid of your hotspot you need to make sure that the cover is properly closed. Check all 4 screws and tighten them fully to ensure the waterproofing
