Potentially Explosive Atmosphere; Traffic Security - Huawei ETS8121 User Manual

Pacemaker manufacturers recommend that a minimum
distance of 15 cm be maintained between a device and a
pacemaker to prevent potential interference with the
pacemaker. If you are using a pacemaker, use the device on
the opposite side of the pacemaker and do not carry the
device in your front pocket.

Do not power on your device at refueling points such as service
stations. Comply with restrictions on the use of radio equipment
in fuel depots, storage, and distribution areas, and chemical
plants. In addition, adhere to restrictions in areas where
blasting operations are in progress. Before using the device,
watch out for areas that have potentially explosive
atmospheres that are often, but not always, clearly marked.
Such locations include areas below the deck on boats,
