Frequently Asked Questions
Can I use flasher/emitters that I have already installed in the system
to connect to the MRF-300?
Yes, the flashers are compatible if they use 3.5mm mono mini plugs with the same
polarity (Tip is data, sleeve is ground).
I am getting inconsistent operation regardless of flasher level or
position.
Some components are easily overloaded with IR from nearby flashers. Prevent IR from
affecting the problem component from other flashers or the front panel blaster by set-
ting the device to a specific IR Line Output instead of ALL, then adjust the Line Output.
I have a row of identical TV’s. I’ve correctly set the flasher outputs
using the Editor software, yet when I send a command to one of
them, the TV next to the selected TV also responds. How do I stop
this?
First, check the RF ID#, if the RF ID# is set to 0, IR routing does NOT work.The RF
ID# from 1-9 or A-F must be set on both the remote control and the bottom of the
MRF-300. Second, check that an opaque material like electrical tape is used to cover
the flasher and the front panel sensor of each of the TV’s. Sometimes several layers are
necessary.
How can I increase the range of the remote control?
Often, you can increase range by adjusting the range screw and/or repositioning the
RFX-150.
If you still can’t get the range you need, consider installing additional
RFX-150 RF Sensors in the areas with poor range by concealing wire runs to
nearby attic or crawl space locations.
