IMPORTANT: Computer User Health Information
Use of a keyboard, mouse, or trackball may be linked to serious injuries or discomfort. Recent medical research of
occupational Injuries has linked normal, seemingly harmless activities as a potential cause of Repetitive Stress Injuries
("RSI"). Many factors may be linked to the occurrence of RSI, including a person's own medical and physical condition,
overall health, and how a person positions and uses his or her body during work and other activities (including use of
a keyboard, mouse, or trackball). Some studies suggest that the amount of time a person uses a keyboard, mouse, or
trackball may also be a factor. Consult a qualified health professional for any questions or concerns you may have
about these risk factors.
When using a keyboard, mouse, or trackball, you may experience occasional discomfort in your hands, arms,
shoulders, neck, or other parts of your body. However, if you experience symptoms such as persistent or recurring
discomfort, pain, throbbing, aching, tingling, numbness, burning sensation, or stiffness, even if such symptoms occur
while you are not working at your computers. DO NOT IGNORE THESE WARNING SIGNS. PROMPTLY SEE A QUALIFIED
HEALTH PROFESSIONAL. These symptoms can be signs of sometimes permanently disabling RSI disorders of the
nerves, muscles, tendons, or other parts of the body.
CAUTION: Never spray liquid cleaner directly on the trackball

IMPORTANT : Informations sur la santé de l'utilisateur
L'utilisation de claviers, souris ou trackballs peut être liée à des blessures ou inconforts. Des études médicales
récentes sur les blessures au travail ont lié des activités paraissant bénignes à des microtraumatismes répétés.
Ces derniers peuvent découler de nombreux facteurs, dont l'état de santé de l'utilisateur, ainsi que la position
adoptée et la manière dont le corps est sollicité durant son travail (usage de claviers, souris et trackballs inclus). Selon
certaines recherches, le temps qu'une personne passe à utiliser de tels outils peut également avoir une incidence.
Nous vous recommandons d'en parler à un professionnel de la santé si vous avez des questions à ce sujet.
L'usage répété d'un clavier, d'une souris ou de trackballs est susceptible d'entraîner un inconfort au niveau des mains,
des bras, des épaules, du cou, et d'autres parties du corps. Si vous ressentez des symptômes persistants et récurrents
(inconfort, douleur, pulsations, courbatures, picotements, engourdissement, sensation de brûlure, raideur), même en
dehors de vos heures de travail, N'IGNOREZ PAS CES SYMPTÔMES. CONSULTEZ RAPIDEMENT UN PROFESSIONNEL DE
LA SANTÉ. Il est possible que cela mène à des microtraumatismes répétés au niveau des nerfs, muscles, tendons, etc.
