PROBLEM PROBABLE CAUSE AND SOLUTION
Unit will not learn IR commands from certain brands and
models of remotes.
a) Because of the wide variety of IR coding and
timing relationships (there are no industry
standards), there are some IR commands that are
not learnable by the Dragon Drop-IR™.
Be sure to test all components first to see that
their IR command codes are learnable by Dragon
Drop-IR and are executable by the MRC44 before
selecting final components for the system.
To aid you in this selection, see CAUTION card
included with these instructions for the latest
information relating to code compatibility.
NOTE: Certain IR commands that are not
normally learnable, or those that operate more
correctly when learned with special techniques at
Xantech, are available on the CD ROM that
comes with Dragon. These, and the most recent
updates to these files, are available on the
Xantech web site at www.xantech.com. Contact
Technical Support for details.
b) Components using IR carriers higher than 71 kHz
cannot be learned directly. Most are learnable,
however, when down-converted by Xantech
products such as the 291P, PMS12, 291-455,
MS455, etc. Refer to the Xantech Product
Catalog and contact Technical Support for details.
Be sure you have the Make and Model number of
the component and its remote before contacting
Technical Support.
"Record ERROR, try again" shows on screen while
learning IR commands.
Sometimes the command "takes" but does not operate
the device.
This may occur if you hold the "teaching" remote too far
away, too close, or at too great an angle to the rear of
the MRC44, or, IR interference is present.
Also, with some remotes, you may be holding down the
buttons for too long or too short a period of time when
"teaching" the commands.
Do the following:
a) Repeat the Learning procedures.
You may have to experiment with the distance the
remote is held away from the IR SENSOR on the
back of the MRC44. It may need to be as much
as 10" away, but usually not closer than 1/2".
b) Vary the amount of time you hold down the
"teaching" remote's buttons. Sometimes only a
brief tap is necessary.
c) Be sure there are no sources of strong IR
interference near the MRC44 (such as CFL lamps,
TVs, Your Computer Monitor, Neon lighting, etc.).
Shade or move the location of the MRC44 as
necessary.
