URC-2
10. Factory Learned IR Commands. Certain atypical IR commands that are not 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. Please use
them whenever possible to save time and to have cleaner operating code.
BATTERY REPLACEMENT
When the batteries decline to the point where they need replacement, the Status LED on the URC-2 will
begin to glow or blink Amber with a command signal. At this point the unit may default to the TV bank and/
or there will be erratic response to IR commands.
• Simply remove the old batteries and replace them with 4 new “AAA” Batteries (Alkaline), referring to Figs.
3 & 4.
• Memory contents, without the batteries, will be retained for 8 hours or more, giving you ample time for
replacement.
Conserving Battery Power
The length of time the batteries will last is highly variable, since it depends on how frequently the remote
is used. If you find battery consumption higher than expected, do the following to maximize battery life:
1. Use only high quality Alkaline batteries (AAA) for replacement.
2. If most of your URC-2 usage does not require the lighted panel, battery life can be extended
considerably by turning it off so that it does not come on when moved, or when a key is pressed.
Turning the Lighted Panel OFF. Simply press the VOL Up and VOL Down buttons simultaneously
until you see the panel turn OFF (5 seconds).
Turning the Lighted Panel ON. Turn it back on at any time by pressing the VOL Up and VOL Down
buttons simultaneously until you see the panel turn ON (5 seconds).
NOTE: The source key LED's will still light up to show last selected source even when the panel lighting
is OFF.
3. If the URC-2 has been programmed using the DD4 software, the "Sleep" Time-out can be adjusted
as referred to in item 5, page 12. The shorter the time, the lower the battery consumption.
TROUBLESHOOTING
If you encounter problems, review each of the following items and take corrective action as described. If
problems persist, contact Xantech Technical Support.
1. The unit does not consistently learn IR commands. The Status LED blinks Red frequently (error)
or the steady Green stays on (not accepting the command).
This can occur if you hold the "teaching" remote too far away, at too great an angle, or offset too far
vertically from the front of the IR window of the URC-2. It may also occur if there is IR interference
present.
Do the following:
a) Be sure the batteries in the "teaching" remote are fresh.
b) Repeat the learning process as needed, varying the distance, angle and alignment between the
two remotes. In some cases, you may need to move the units close enough to touch to get sufficient
signal strength from the "teaching" remote.
