Precautions

This symbol is intended to alert the user of important operating and maintenance (servicing) instructions in the literature provided with the equipment.

This symbol is intended to alert the user of the presence of uninsulated dangerous voltage within the product’s enclosure that may present a risk of electric shock.

CautionRead Instructions • Read and understand all safety and operating

instructions before using the equipment. Retain Instructions • The safety instructions should be kept for future

reference.Follow Warnings • Follow all warnings and instructions marked on the

equipment or in the user information.Avoid Attachments • Do not use tools or attachments that are not

recommended by the equipment manufacturer because they may be hazardous.

WarningPower sources • This equipment should be operated only from the power source

indicated on the product. This equipment is intended to be used with a main power system with a grounded (neutral) conductor. The third (grounding) pin is a safety feature, do not attempt to bypass or disable it.

Power disconnection • To remove power from the equipment safely, remove all power cords from the rear of the equipment, or the desktop power module (if detachable), or from the power source receptacle (wall plug).

Power cord protection • Power cords should be routed so that they are not likely to be stepped on or pinched by items placed upon or against them.

Servicing • Refer all servicing to qualified service personnel. There are no user-serviceable parts inside. To prevent the risk of shock, do not attempt to service this equipment yourself because opening or removing covers may expose you to dangerous voltage or other hazards.

Slots and openings • If the equipment has slots or holes in the enclosure, these are provided to prevent overheating of sensitive components inside. These openings must never be blocked by other objects.

Lithium battery • There is a danger of explosion if battery is incorrectly replaced. Replace it only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s instructions.

Ce symbole sert à avertir l’utilisateur que la documentation fournie avec le matériel contient des instructions importantes concernant l’exploitation et la maintenance (réparation).

Ce symbole sert à avertir l’utilisateur de la présence dans le boîtier de l’appareil de tensions dangereuses non isolées posant des risques d’électrocution.

AttentionLire les instructions• Prendre connaissance de toutes les consignes de

sécurité et d’exploitation avant d’utiliser le matériel.Conserver les instructions• Ranger les consignes de sécurité afin de pouvoir

les consulter à l’avenir.Respecter les avertissements • Observer tous les avertissements et consignes

marqués sur le matériel ou présentés dans la documentation utilisateur.Eviter les pièces de fixation • Ne pas utiliser de pièces de fixation ni d’outils

non recommandés par le fabricant du matériel car cela risquerait de poser certains dangers.

AvertissementAlimentations• Ne faire fonctionner ce matériel qu’avec la source d’alimentation

indiquée sur l’appareil. Ce matériel doit être utilisé avec une alimentation principale comportant un fil de terre (neutre). Le troisième contact (de mise à la terre) constitue un dispositif de sécurité : n’essayez pas de la contourner ni de la désactiver.

Déconnexion de l’alimentation• Pour mettre le matériel hors tension sans danger, déconnectez tous les cordons d’alimentation de l’arrière de l’appareil ou du module d’alimentation de bureau (s’il est amovible) ou encore de la prise secteur.

Protection du cordon d’alimentation • Acheminer les cordons d’alimentation de manière à ce que personne ne risque de marcher dessus et à ce qu’ils ne soient pas écrasés ou pincés par des objets.

Réparation-maintenance • Faire exécuter toutes les interventions de réparation-maintenance par un technicien qualifié. Aucun des éléments internes ne peut être réparé par l’utilisateur. Afin d’éviter tout danger d’électrocution, l’utilisateur ne doit pas essayer de procéder lui-même à ces opérations car l’ouverture ou le retrait des couvercles risquent de l’exposer à de hautes tensions et autres dangers.

Fentes et orifices • Si le boîtier de l’appareil comporte des fentes ou des orifices, ceux-ci servent à empêcher les composants internes sensibles de surchauffer. Ces ouvertures ne doivent jamais être bloquées par des objets.

Lithium Batterie • Il a danger d’explosion s’ll y a remplacment incorrect de la batterie. Remplacer uniquement avec une batterie du meme type ou d’un ype equivalent recommande par le constructeur. Mettre au reut les batteries usagees conformement aux instructions du fabricant.

Consignes de Sécurité • Français

Sicherheitsanleitungen • DeutschDieses Symbol soll dem Benutzer in der im Lieferumfang enthaltenen Dokumentation besonders wichtige Hinweise zur Bedienung und Wartung (Instandhaltung) geben.

Dieses Symbol soll den Benutzer darauf aufmerksam machen, daß im Inneren des Gehäuses dieses Produktes gefährliche Spannungen, die nicht isoliert sind und die einen elektrischen Schock verursachen können, herrschen.

AchtungLesen der Anleitungen • Bevor Sie das Gerät zum ersten Mal verwenden,

sollten Sie alle Sicherheits-und Bedienungsanleitungen genau durchlesen und verstehen.

Aufbewahren der Anleitungen • Die Hinweise zur elektrischen Sicherheit des Produktes sollten Sie aufbewahren, damit Sie im Bedarfsfall darauf zurückgreifen können.

Befolgen der Warnhinweise • Befolgen Sie alle Warnhinweise und Anleitungen auf dem Gerät oder in der Benutzerdokumentation.

Keine Zusatzgeräte • Verwenden Sie keine Werkzeuge oder Zusatzgeräte, die nicht ausdrücklich vom Hersteller empfohlen wurden, da diese eine Gefahrenquelle darstellen können.

VorsichtStromquellen • Dieses Gerät sollte nur über die auf dem Produkt angegebene

Stromquelle betrieben werden. Dieses Gerät wurde für eine Verwendung mit einer Hauptstromleitung mit einem geerdeten (neutralen) Leiter konzipiert. Der dritte Kontakt ist für einen Erdanschluß, und stellt eine Sicherheitsfunktion dar. Diese sollte nicht umgangen oder außer Betrieb gesetzt werden.

Stromunterbrechung • Um das Gerät auf sichere Weise vom Netz zu trennen, sollten Sie alle Netzkabel aus der Rückseite des Gerätes, aus der externen Stomversorgung (falls dies möglich ist) oder aus der Wandsteckdose ziehen.

Schutz des Netzkabels • Netzkabel sollten stets so verlegt werden, daß sie nicht im Weg liegen und niemand darauf treten kann oder Objekte darauf- oder unmittelbar dagegengestellt werden können.

Wartung • Alle Wartungsmaßnahmen sollten nur von qualifiziertem Servicepersonal durchgeführt werden. Die internen Komponenten des Gerätes sind wartungsfrei. Zur Vermeidung eines elektrischen Schocks versuchen Sie in keinem Fall, dieses Gerät selbst öffnen, da beim Entfernen der Abdeckungen die Gefahr eines elektrischen Schlags und/oder andere Gefahren bestehen.

Schlitze und Öffnungen • Wenn das Gerät Schlitze oder Löcher im Gehäuse aufweist, dienen diese zur Vermeidung einer Überhitzung der empfindlichen Teile im Inneren. Diese Öffnungen dürfen niemals von anderen Objekten blockiert werden.

Litium-Batterie • Explosionsgefahr, falls die Batterie nicht richtig ersetzt wird. Ersetzen Sie verbrauchte Batterien nur durch den gleichen oder einen vergleichbaren Batterietyp, der auch vom Hersteller empfohlen wird. Entsorgen Sie verbrauchte Batterien bitte gemäß den Herstelleranweisungen.

Este símbolo se utiliza para advertir al usuario sobre instrucciones importantes de operación y mantenimiento (o cambio de partes) que se desean destacar en el contenido de la documentación suministrada con los equipos.
