3. Pull on the end of the strap until the
chin strap is properly tightened. The chin
strap should be positioned against the
neck, not under the chin. It should be
as tight as possible without hurting or
hindering breathing. See Figure D.
4. Fasten the snap on the free end of the
strap to prevent the strap from trailing in
the air.

devices. If you wear one of these
devices, it is recommended to keep a
safe distance from magnets.
Effect on connected objects
SIM cards, credit cards, debit cards,
badges, magnetic cards in general,
computer media, memories, acoustic
devices, speakers, mechanical watches,
compasses, radios, remote controls
and/or objects or devices, etc. can
be damaged by intense magnetic
fields. They should be kept away from
magnets.

coating to protect them against
corrosion. This coating can chip or crack
due to collisions or high pressure; if the
magnets remain directly exposed to
atmospheric agents, such as humidity,

for a long time, they can oxidize.
Effects on people
According to current knowledge, the
magnetic fields of magnets have no
measurable effect, positive or negative,
on people. It is unlikely that the
magnetic field of a magnet represents
a health hazard, but this risk cannot be
completely excluded. For safety, avoid
direct and prolonged contact with the
magnets.
