PPaaggee 11MMRRFF--225500 BBAASSEESSTTAATTIIOONNIntroductionThe combination of the MX-3000 with it’s companion MRF-250 base stationwill enable you to place your audio/video components out of sight behindclosed doors and/or in another room of your house. The MX-3000 sendsradio signals to the MRF-250 throughout your house (50-100’ away, indoors oroutdoors). The MRF-250 converts your commands to the infrared signals thatcontrol your A/V components.3. Self-adhesive “Flashers” affix to theInfrared sensors on the front panelsof your components. The Flashersrelay commands to components outof sight of the MRF-250’s FrontBlaster. The flashers plug in to theMRF-250’s rear flasher line outputsvia their 10 foot cables.2.The MRF-250’s built-in Front Blaster sends commands tocomponents in the same cabinet space as the MRF-250.1.The MX-30000 remote con-trol sends radio waves inevery direction, so you don’thave to point the remote any-more!

Each MRF-250 is assigned one of 16 unique ID#’s. In operation it’s simple: when youselect a device located in the Den, the MX-3000 only talks to the MRF-250 inthe Den.

The intelligent routing of the MRF-250 will send yourcommands only to the TV you select on your MX-3000. The other identicalTV’s will not receive commands. Of course, if your system utilizes identicalsatellite 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, upto 16 additional MRF-250’s can be installed to control them (thus allowing upto 96 identical components in one house).Parts GuideThe MRF-250 RF Base Station includes:1 - MRF-250 Receiver with integrated antenna1 - Mounting Plate for wall mounting the MRF-2504 - Screws for wall mounting the mounting plate1 - 9V-300mA Power Supply6 - Flashers with 10 foot plug in cables.

However, you can add any number of MX-3000 remote controls toyour home! MX-3000’s are available as an accessory purchase without anMRF-250 for standard system installations that already have an MRF-250.You can add any number of MRF-250 base stations in a standard system aswell. If you need more than six flasher outputs you may add additional MRF-250 receivers as needed by ordering an accessory MRF-250 base station.Do not change the factory default settings in RF Control section of MX-3000Editor when you download to your MX-3000’s. You do not need to utilizeMX3000 Editor’s Program Step 9 (RF Control), since the factory settings willwork fine!Standard Installation — Step by StepSStteepp 11 -- PPrrooggrraamm aanndd DDoowwnnllooaadd ttoo tthhee MMXX--33000000 Connect your MX-3000 to your PC and program the IR commands and macrosas you like.

Make sure that the componentsoperate with the cabinet doors closed or open. If a component is placed too faraway from the front blaster, you will need to utilize the included Flashers pluggedinto the MRF-250’s rear Flasher Line Output jacks.If you have problems with components that are close to the Front Blaster, seethe next page and the section on Front Blaster Overload.SStteepp 77 -- CCoonnnneecctt FFllaasshheerrss ttoo OOuutt ooff SSiigghhtt AA//VV CCoommppoonneennttss IImmppoorrttaanntt NNoottee::TTeesstt tthhee ooppeerraattiioonn BBEEFFOORREEssttiicckkiinngg tthhee ffllaasshheerr iinn ppllaaccee..Use a flashlight to identify the correct location of the component’s IR sensor,then try a few commands while moving the flasher around the face plate ofthe component.

PPaaggee 77MMRRFF--225500 BBAASSEESSTTAATTIIOONNFront Blaster OverloadA few models of audio/video components can be OVERLOADED by the FrontBlaster. If you are having intermittent or inconsistent results with a particularcomponent, try repositioning the MRF-250 and facing the Front Blaster in adifferent direction. If this improves the situation but is impractical, it may benecessary to utilize the self-adhesive flashers only and follow the steps belowto Disable the Front Blaster. This will limit the number of components yourMRF-250 can control to six. If you have more than six components you canpurchase an additional MRF-250 (available as an accessory alone from yourHome Theater Master dealer).

Controlling An Array of Identical TV’s (or VCR’s, Receivers, CD players etc.)There are several considerations to take into account when you are installingan MRF-250 to control an array of identical components:1. You cannot use the Front Blaster to control identical components. Youmust use Flashers instead. You can still use the Front Blaster in a cabinetthat is out of sight of the identical components to control the rest of yoursystem.2. Each identical component must receive IR commands ONLY from a dedicat-ed Flasher affixed to it’s front panel. The IR output of the MX-3000 shouldbe disabled for each identical component. It can still be utilized for the restof your system!3. You must note the NUMBER of the Flasher Output you have utilized forEACH of the identical components.NOTE: If the identical components are near each other the Flashers and theactual sensor window of the component should be blocked with blackelectrical tape (sometimes more than one layer is needed).Identical Components - Step by Step SStteepp 11 -- CCrreeaattee aa DDeevviiccee ffoorr EEaacchh TTVV iinn MMXX--33000000 EEddiittoorrThe MX-3000 can control up to 20 devices.
