Silvercrest SFM 2400 B1 Operation And Safety Notes page 11

Switch the product off on aeroplanes, in hospitals, service
rooms, or near medical electronic systems. The wireless
signals transmitted could impact the functionality of sensitive
electronics.
Keep the product at least 20 cm from pacemakers
or implantable cardioverter defibrillators, as the
electromagnetic radiation may impair the functionality of
pacemakers.
The radio waves transmitted could cause interference in
hearing aids.
Do not place the product near flammable gasses or
potentially explosives areas (e.g. paint shops) with the
wireless components on, as the radio waves emitted can
cause explosions and fire.
The range of the radio waves varies by environmental
conditions. In the event of wireless data transmission,
unauthorised third parties receiving the data cannot be
excluded.
DANGER! Keep batteries out of reach of
children. If accidentally swallowed seek
immediate medical attention.
WARNING! EXPLOSION HAZARD!
Never recharge non-rechargeable batteries. Do not
short-circuit batteries or open them. Overheating, fire or
bursting can be the result. Never throw batteries into fire
or water. Do not exert mechanical loads to batteries.
