HI,

DIRECT CODE ENTRY

Step 1:Press and hold the device key (TV, VCR, SAT, etc) you wish to program. The illuminated ON/OFF key(*) turns on and remains on. If you release the device key at any time during theDirect Code Entryprocedure, the illuminated ON/OFF key blinks 4 times, and the process is exited.
Step 2:While holding down the device key, use the number keys (0-9) on the keypad to enter your equipment's code. While you are pressing the numbers, the illuminated ON/OFF key turns off.

FOR CODES CHE THE BELLOW ADDED LINK
Step 3:After the 4th number is entered, the illuminated ON/OFF key turns on. At this time, release the device key. If the illuminated ON/OFF key turns off, you have entered a valid code and have followed the correct procedure. If you enter a code that is not in the Code Lists or you do not follow all of the correct steps for Direct Code Entry, the illuminated ON/OFF key blinks 4 times when the component key is released - an indication that a programming error has occurred. In that case, repeat the process from Step 1 and try the next code in the list.
Step 4:To confirm that remote is programmed with the correct code for maximum functionality, test it. If some of the features of your equipment do not work, try programming the remote with a different code in the list until you find the code that allows the remote to control the majority of your component's functions as different codes can provide different levels of functionality.
* some models like the RCR450 have a LED indicator light in place of the illuminated ON/OFF key.

AUTO CODE SEARCH

If your component's brand is not listed in the code tables, or if you have tried all of the codes for your brand and the remote does not operate your component, try the Auto Code Search method below. The remote will cycle through all of the codes, in the event that your code is listed under another brand. TheAuto Code Searchmethod may take a long time because the remote searches through all of the codes in its memory for the code that operates your component. Therefore, if your brand appears in the code list you should try first theDirect Code Entrymethod described above.
Step 1:Manually turn on the device you want the remote to control (TV, VCR, DVD, cable box, etc.).
Step 2:Press and hold the device button (TV, VCR, DVD, etc.) you wish to program. The illuminated ON/OFF key turns on and remains on.
Step 3:While holding the component button down, press and hold the ON/OFF key. The illuminated ON/OFF key turns off.
Step 4:After holding down both keys for 3 seconds, the illuminated ON/OFF key turns back on.
Step 5:Release both keys. The illuminated ON/OFF key remains on.
Step 6:Press and release the PLAY button, then wait 5 seconds to see if your component turns off. If your component does not respond, continue to press the PLAY key every 5 seconds until your component turns off. Each time you press the PLAY key, the illuminated ON/OFF key blinks and a block of ten codes are sent to your component. This process continues until all of the codes have been searched. If your device has not turned off after all codes have been searched, the illuminated ON/OFF key blinks 4 times and turns off. The Auto Code Search Entry method is exited.
Step 7:When your equipment turns off, you know'll that the correct code is in the last block of 10 codes sent. Press and release the REVERSE key, Wait 2 seconds to see if your component turns on again. If your component does not respond, continue to press the REVERSE button every 2 seconds until your component turns on again. This will isolate the correct code in the last block of codes sent. Each time the REVERSE key is pressed, the illuminated ON/OFF key blinks.
Note:If you accidentally press the REVERSE button after your device responds, press and release the FORWARD key. Wait 2 seconds to see if your component turns off again.
Step 8:Once your component turns on, you have found the correct code. You must save the new code by pressing and releasing the STOP key. The illuminated ON/OFF key turns off.
Important:You must press the STOP key to save the code or the correct code will not be stored!

MANUAL CODE ENTRY

Step 1:Manually turn on the component you want the remote to control and keep the remote pointed at it.
Step 2:Press and hold the component key (TV, VCR, DVD, etc.) you wish to program. The LED indicator light turns on and remains on.
Step 3:While holding the component key down, press and hold the ON/OFF key. The LED indicator light turns off.
Step 4:After holding down both keys for 3 seconds, the LED indicator light turns back on.
Step 5:Release both keys. The LED indicator light remains on.
Step 6:Press and release the ON/OFF key repeatedly until your component turns off. Each time you press the ON/OFF key, the LED indicator light blinks, and the next code in the list is sent. This process continues until all of the codes in the Code Lists have been searched. If your component turns off, you have found the correct code.
Because there are so many codes, you may have to press the ON/OFF key many times - possibly up to 200 times.
Step 7:Once you have found the correct code, you must save the new code by pressing and releasing the STOP key.

CODE RETRIEVAL

If you used one of the Code Search methods above to program your remote you may want to record the codes for future reference. Retrieving the actual code and writing it down will save you time if you ever need to program the remote again (when you change the batteries for example). If the codes are recorded, you can use the Direct Entry method to reprogram your remote to control your device, which is quick and easy.
Step 1:Press and hold the component key (TV, DVD, etc.) whose code you wish to retrieve. The illuminated ON/OFF key turns on.
Step 2:While holding the device key down, press and hold the INFO key. The illuminated ON/OFF key will turn off.
Step 3:After holding down both keys for 3 seconds, the illuminated ON/OFF key turns back on.
Step 4:Release both keys. The illuminated ON/OFF key remains lit.
Step 5:Starting with the number 1 key, press and release each number key on the keypad in the following order: 1 to 9, then 0. The number that causes the illuminated ON/OFF key to blink is the first number of the code.
Note:
TV codes begin with the number 1
VCR codes begin with the number 2
DVD codes begin with the number 3
Satellite receivers and cable boxes, codes begin with the number 5.
Step 6:Repeat step 5 until you have retrieved all 4 numbers in the code.
Step 7:After the fourth number is retrieved, the illuminated ON/OFF key blinks briefly, then turns off.
Note:To exit theCode RetrievalMode, press and release the "GO BACK" button at any time.
