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.
NOTE: Before performing a code search for a DVD player or a VCR, turn on the device and
insert the required media.
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 (red light) blinks twice,
then release SET.
3. Enter 9 - 9 - 1.The LED will blink twice.
4. Aim the remote control at the TV and slowly alternate
between pressing POWER and TV. Stop when the TV turns off
(after pressing POWER). If the device does not have a Power
key, you can substitute another function, such as digits 0 ~ 9 ,
CH up, or PLAY).
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 release SET.The LED will
blink twice.
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.

If you have set up the remote control using the Searching For Your Code procedure
as above, you may need to find out which four-digit code is operating
your equipment. For example, to find out which code is operating your
TV:

2. Press and hold SET until the LED (red light) blinks twice,
then release SET.
3. Enter 9 - 9 - 0.The LED will blink twice.

seconds, count the LED blinks (e.g., three blinks = 3) and
write down the number in the leftmost box in the TV
code boxes on page 8.
NOTE: If a code digit is "0", the LED will not blink.
5. Repeat step 4 (on the previous page) three more times for
remaining digits.Use 2 for the second digit, 3 for the third
digit, and 4 for the fourth digit.Write down the code digits
in the remaining TV code boxes on page 8.
6. To check for codes of other devices, repeat steps 1
through 5
