The MRF-250C converts commands to infrared signals that control you AV components. This allows the UR5L-9000LRF to send radio signals throughout your house whether you be indoors, outdoors, or even up to 100’ away. 1. The UR5L-9000LRF remote control sends radio waves in every direction, so you don’t have to point the remote at the device anymore! 2. The MRF-250C’s built-in Front Blaster sends commands to components in the same cabinet space as the MRF-250C. 3. Self-adhesive “Flashers”affix to the Infrared sensors on the front panels of your components. The Flashers relay commands to components out of sight of the MRF-250C’s Front Blaster. The flashers plug in to the MRF-250C’s rear allowing the flasher line to output via their 10 foot cables. Page 2 MRF-250C BASESTATION Features and Benefits No More Pointing - Radio Waves Penetrate Walls, Doors and Floors The MRF-250C receives the RF signals of the UR5L-9000LRF remote control from any direction. You no longer need to point the remote control at any of your AV components. You can also place the components distracting blinking lights and displays behind closed doors or in another room! Reliable Control Throughout Your House The MRF-250C receives RF signals from your UR5L-9000LRF from within a radius of 50 to 100 feet enabling you to control out of sight cable boxes or components such at those behind walls or closed doors. Range depends on the structure of your home and the amount of interference generated by computers, microprocessors and other devices within and nearby your home. Control an Equipment Locations Controlled From Any UR5L-9000LRF Each UR5L-9000LRF can be programmed to operate equipment in another room, by installing an MRF-250C base station at each location. The MRF-250C is assigned one of 16 unique ID#s. In operation it is simple: when you select a device located in the den, the UR5L-9000LRF only signals to the MRF-250C in the den. No Pointing Remote Controls In Every Room You can opt to control a multi-room or multi-zone system via RF remote control by placing a UR5L-9000LRF in each room of your home. Parts Guide The MRF-250C RF Base Station includes: 1 - MRF-250C Receiver with integrated antenna 1 - Mounting Plate for wall mounting the MRF-250C 4 - Screws for wall mounting the mounting plate 1 - 9V-300mA Power Supply 6 - Flashers with 10 foot plug in cables. Page 3 MRF-250C BASESTATION MRF-250C Details Using the four enclosed screws, you can choose to fix the mounting plate to a wall or the back of your component cabinet. The MRF-250C’s slots enable the mounting plate‘s matching guides to slide and “snap”into place for quick and easy mounting on the wall. Front Blaster sends Infrared commands to all AV components in the same cabinet space. Red POWERLED Lights up when the MRF-250C’s power supply is plugged into an active AC outlet. Red S TATUSLED Lights up when the MRF-250C receives an RF signal from the UR5L-9000LRF. The MRF-250C Mounting Plate Page 4 MRF-250C BASESTATION Bottom panel Dial sets the Receiver ID# when more than one MRF-250C receiver is used. Included 9V power supply plugs into the MRF-250C’s power connector. Integrated Antenna swings in any direction to optimize RF recep- tion and range. Six Rear Flasher Line Output Jacks connect flashers for control of A/V components out of sight of the MRF- 250C’s Front Blaster. Six Plug-In Flashers are supplied with 10 foot cables and six extra self-adhesive pads in case a flasher has to be repositioned. A Standard MRF-250C System A standard system utilizes one UR5L-9000LRF and one MRF-250C to control an equipment location. Step 1 - Place the MRF-250C The MRF-250C should be placed so that the Front Blaster will control as many of the system’s AV components as possible. If you are connecting the outboard flashers to the rear Flasher outputs only, the MRF-250C may be concealed and mounted to the rear wall or back of the system cabinet. The mounting plate slides apart from the receiver, screws to the wall or cabinet with the enclosed screws, then the receiver is slid back into place. Step 2 - Connect the Power Supply and Insert the Batteries Connect the 9V power supply to an active UNSWITCHED AC outlet. The MRF- 250C must always be powered up to operate. The red P OWERLED should Light up. Insert the batteries in the UR5L-9000LRF remote control. Step 3 - Test the UR5L-9000LRF Ob…
