SEARCHING FOR YOUR CODE
If your device does not respond to the
remote control after trying all codes
listed for your brand, or if your brand is
not listed at all, try searching for your
code. For example, to search for a code
for your TV:
1. On the remote control, press TV once.
2. Press and hold SET until the LED
blinks twice, then release SET.
3. Enter 9 - 9 - 1.The LED will
blink twice.
4. Aim the remote control at the the
TV and slowly alternate between
pressing POWER and TV. Stop when
the TV turns off.
NOTE: In the search mode, the remote
control will send IR codes from its library
to the selected device, starting with the
most popular code first.
5. To lock in the code, press and hold
SET until the LED blinks twice, then
release SET.
6. To search for the codes of your other
devices, repeat steps 1 through 5, but
substitute the appropriate device key
for the device you are searching for.

I found this off a urc-4605 manual online but I think it works for all models worked for my urc4640b00
