URC-2
c) On some "teaching" remotes, the internal IR emitter is considerably offset from the center of the
case. Also the "learning" sensor on the URC-2 is somewhat off center as well ... it is in-line with
the SAT key LED. You may have to experiment with lateral displacement of the remotes to get
the emitter and sensor devices in good alignment.
d) Experiment with different key press times on the "teaching" remote. Usually a brief "tap" is all that
is necessary.
e) Be sure there are no sources of strong IR interference (such as CFL lamps, TVs, Neon lighting,
etc.) near the URC-2. Shade the IR window of the URC-2 if necessary.
2. The 2nd URC-2, after a Cloning Transfer, does not output IR commands.
Corrupted data in the 2nd URC-2 may have prevented a proper data transfer.
a) Do a Clear Memory procedure on the 2nd URC-2 (Fig. 12).
b) Repeat the Cloning procedure (Figs. 13 &14).
3. The unit does not respond to any key presses.
In rare instances, while programming the URC-2, or cloning from one to another, the unit may lock up
and not respond to any key presses.
If this occurs, temporarily remove one battery, then reinstall it. This will reset the unit and restore
operation. No user programming will be lost.
4. 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 URC-2
or the DD4 Dragon Drop-IR
system.
Be sure to test all components first to see that their IR command codes are learnable and
executable by the URC-2 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: DD4 Users. Certain IR commands that are not normally learnable, or those that operate more
correctly when learned with special techniques at Xantech, plus a library of IR codes for Xantech
products, are available on the CD ROM that comes with DD4. These, and the most recent updates to
these files, are also available on the Xantech web site at www.xantech.com. In addition, if necessary,
they can be obtained from Xantech on a 3-1/2" floppy disc. 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.
