Installation Notes
- Ensure that rack or other confined installation does not restrict the airflow required for safe and reliable operation of the equipment. It is important to ensure that the 40°C maximum operating temperature for the equipment is not exceeded.
- Amplifiers will not switch on from standby mode unless an input signal is present or the standby switch is toggled.
- Standby control and fault indication
Important Safety Instructions
English
- Read these instructions.
- Keep these instructions.
- Heed all warnings.
- Follow all instructions.
- Do not use this apparatus near water.
- Clean only with a dry cloth.
- Do not block any ventilation opening. Install in accordance with the manufacturer's instructions.
- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
- To reduce the risk of electrical shock, the power cord shall be connected to a mains socket outlet with a protective earthing connection.
- Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
- Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
- Do not unplug the unit by pulling on the cord, use the plug.
- Unplug this apparatus during lightning storms or when unused for long periods of time.
- Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
- The appliance coupler, or the AC Mains plug, is the AC mains disconnect device and shall remain readily accessible after installation.

- Pour réduire le risque d'électrocution, le cordon d'alimentation doit être connecté à une prise de courant avec une mise à la terre de protection.
- Respectez le dispositif de protection de mise à la terre de la prise secteur. Une prise polarisée est équipée de deux fiches, l'une plus large que l'autre. Une prise avec borne de terre est équipée de deux fiches et d'une borne de terre. La fiche large, ou la borne de terre, est garante de votre sécurité. Si la fiche secteur fournie avec l'appareil ne correspond pas à la prise secteur de votre installation, faites remplacer cette dernière par un électricien.
- Disposez les câbles de sorte qu'ils ne puissent pas être piétinés, coincés ou pincés; une attention toute particulière doit être accordée au niveau des prises secteur et de l'embase secteur de l'appareil.
- Ne débranchez pas l'appareil en tirant sur le cordon. Utilisez la fiche.
- Débranchez cet appareil du secteur lors des orages ou des longues périodes d'inutilisation.
- Confiez toute réparation à un technicien qualifié. L'intervention d'un technicien est nécessaire dans les cas suivants : le cordon d'alimentation ou la prise secteur sont endommagés, des corps étrangers ou du liquide se sont introduits dans l'appareil, l'appareil a été exposé à la pluie ou à l'humidité, l'appareil montre des signes de dysfonctionnement ou est tombé.
- Le coupleur de l'appareil, ou la fiche secteur, est le dispositif de déconnexion du secteur et doit rester facilement accessible après l'installation.
