Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better!  \nGetting Started  \nWe recommend that you:  \n• Unpack the equipment carefully and save the original box and packaging materials for possible future shipment.  \n• Review the contents of this user manual.  \n[Go to](Go to www.kramerav.com/downloads/EXT3-C-WP-XR-T to check for)[ ](Go to www.kramerav.com/downloads/EXT3-C-WP-XR-T to check for)[www.kramerav.com/downloads/EXT3-C-WP-XR-T](Go to www.kramerav.com/downloads/EXT3-C-WP-XR-T to check for)[ to check for](Go to www.kramerav.com/downloads/EXT3-C-WP-XR-T to check for) up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate) .  \nAchieving Best Performance  \n• Use only good quality connection cables (we recommend Kramer high-performance, high-resolution cables) to avoid interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables) .  \n• Do not secure the cables in tight bundles or roll the slack into tight coils.  \n• Avoid interference from neighboring electrical appliances that may adversely influence signal quality.  \n• Position your Kramer EXT3-C-WP-XR-T away from moisture, excessive sunlight and dust.  \nSafety Instructions  \nCaution:  \n• This equipment is to be used only inside a building. It may only be connected to other equipment that is installed inside a building.  \n• For products with relay terminals and GPI\\O ports, please refer to the permitted rating for an external connection, located next to the terminal or in the User Manual.  \n• There are no operator serviceable parts inside the unit.  \nWarning:  \n• Use only the power cord that is supplied with the unit.  \n• Disconnect the power and unplug the unit from the wall before installing.  \n• Do not open the unit. High voltages can cause electrical shock! Servicing by qualified personnel only.  \n• To ensure continuous risk protection, replace fuses only according to the rating specified on the product label which is located on the bottom of the unit.  \nRecycling Kramer Products  \nThe Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled. To comply with the WEEE Directive, Kramer Electronics has made arrangements with the European Advanced Recycling Network (EARN) and will cover any costs of treatment, recycling and recovery of waste Kramer Electronics branded equipment on arrival at the EARN facility.
