Don’t touch the antenna area unnecessarily whilst connected. This can affect your modem performance
and reduce the signal quality.
Store the modem out of the reach of children. The modem may cause injury or get damaged.
The modem contains sensitive electronic circuitry. Do not expose the modem to any liquids, high
temperatures or shock.
Only use original accessories or accessories that are authorized by the manufacturer. Using unauthorized
