The MX-3000 sends radio signals to the MRF-250 throughout your house (50-100’ away, indoors or outdoors). The MRF-250 converts your commands to the infrared signals that control your A/V components. 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-250’s Front Blaster. The flashers plug in to the MRF-250’s rear flasher line outputs via their 10 foot cables. 2.The MRF-250’s built-in Front Blaster sends commands to components in the same cabinet space as the MRF-250. 1.The MX-30000 remote con- trol sends radio waves in every direction, so you don’t have to point the remote any- more! PPaaggee 22 MMRRFF--225500 BB AASSEE SS TTAATTIIOONN Features and Benefits NNoo MMoorree PPooiinnttiinngg -- RRaaddiioo WWaavveess PPeenneettrraattee WWaallllss,, DDoooorrss aanndd FFlloooorrss The MRF-250 receives the RF signals of the MX-3000 remote control from any direction. You no longer need to point the remote control at any of your A/V components. You can also place the components distracting blinking lights and displays behind closed doors and/or in another room! RReelliiaabbllee CCoonnttrrooll TThhrroouugghhoouutt YYoouurr HHoouussee The MRF-250 receives RF signals from your MX-3000 from within a radius of 50 to 100 feet enabling you to control out of sight audio/video components behind walls and 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. UUpp TToo SSiixxtteeeenn EEqquuiippmmeenntt LLooccaattiioonnss CCoonnttrroolllleedd FFrroomm AAnnyy MMXX--33000000 Each MX-3000 can be programmed to operate equipment placed throughout the house, by installing an MRF-250 base station at each location. Each MRF- 250 is assigned one of 16 unique ID#’s. In operation it’s simple: when you select a device located in the Den, the MX-3000 only talks to the MRF-250 in the Den. When you select a device located in the Family Room, the MX-3000 only talks to it! NNoo PPooiinnttiinngg RReemmoottee CCoonnttrroollss IInn EEvveerryy RRoooomm You can opt to control a multi-room or multi-zone system via RF remote con- trol by placing an MX-3000 in each room of your home. CCoonnttrrooll AA MMeeddiiaa RRoooomm AArrrraayy ooff IIddeennttiiccaall TTVV’’ss The MRF-250’s unique assignable IR flashers enable your installation to control up to six identical TV’s. The intelligent routing of the MRF-250 will send your commands only to the TV you select on your MX-3000. The other identical TV’s will not receive commands. Of course, if your system utilizes identical satellite receivers, cable boxes, VCR’s or disc changers you can utilize IR rout- ing just as easily for them. If you have more than six identical components, up to 16 additional MRF-250’s can be installed to control them (thus allowing up to 96 identical components in one house). Parts Guide The MRF-250 RF Base Station includes: 1 - MRF-250 Receiver with integrated antenna 1 - Mounting Plate for wall mounting the MRF-250 4 - Screws for wall mounting the mounting plate 1 - 9V-300mA Power Supply 6 - Flashers with 10 foot plug in cables. PPaaggee 33 MMRRFF--225500 BB AASSEE SS TTAATTIIOONN The MRF-250’s slots enable the Mounting Plate’s matching guides to slide and “snap” into place for mounting on the wall. Using the four enclosed screws, you can choose to fix the mounting plate to a wall or the back of your component cabinet. Front Blaster sends Infrared com- mands to all A/V components in the same cabinet space.
