Introduction

The combination of the MX-3000 with it’s companion MRF-250 base station
will enable you to place your audio/video components out of sight behind
closed doors and/or in another room of your house. 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 con­trol sends radio waves in
every direction, so you don’t
have to point the remote any­more!

Features and Benefits

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!

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.

Each MX-3000 can be programmed to operate equipment placed throughout
the house, by installing an MRF-250 base station at each location. Each MRF­250 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!

You can opt to control a multi-room or multi-zone system via RF remote con­trol by placing an MX-3000 in each room of your home.

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 rout­ing 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).
