Error code RC3

Keep pressing OK + 2 or OK + 3 depending on the case for about 5 seconds.
The remote should work then.

Hope this helps!

Please visit these sites to get some details. Set-up code list and proceedings of many brand remote controls are given in detail.
Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device./

press and hold the numbered button
corresponding to the code on the
remote control simultanously with OK button for approx 10 secondes
ex: if rc1 appear on panel press number 1 and ok button on the remote for approx 10 sec. ( if RC2 press number 2, if RC3 press number 3)

Check it with an other code. Then an other. Choose one code, that gives maximum functionality. This is a trial and error method. Never expect that a universal remote control will function to all the functions to a TV. If you wish to get more setup codes to check, visit this site, and pull up older posts there. Setup code list to many popular remote controls are given. Try other codes. Check these two sites.

Hello
Codes for ESA TV with RCA RCR312w are:
10812, 10171, 11963

1* Manually turn on the component you want the remote to

control.

2* Locate the enclosed Code Lists. Find the list for the

component you wish to program. Find your component's

brand. You will see a listing of four-digit codes for each

brand. If your brand isn't listed, use one of the Code Search
methods to program the remote control.

3* Press and hold the component key (TV,

VCR•DVD, SAT•CBL) you wish to

program. The illuminated ON•OFF key

turns on and remains on. If you release

the component key at any time during the Direct Code

Entry procedure, the illuminated ON•OFF key blinks four
times, and the process is exited.

4* While holding down the component key, consult the

Code Lists for the four-digit code that corresponds to your

component's brand and use the number keys (0-9) on the

keypad to enter it. While you are pressing the numbers, the
illuminated ON•OFF key turns off.

5* After the fourth number is entered, the illuminated ON•OFF

key turns on. At this time, release the component key. If the

illuminated ON•OFF key turns off, you have entered a valid

code and have followed the correct procedure for Direct
Code Entry

If you enter a code number that is not in the Code Lists or

you do not follow all of the steps for Direct Code Entry,

the illuminated ON•OFF key blinks four times when the

component key is released. This is an indication that a

programming error has occurred. In that case, repeat the

Direct Code Entry process from step 3.

Tip: Throughout the programming of each key, be sure to keep the

remote pointed at the IR sensor of the component you are currently
programming the remote to control.

6* To confirm that the component key is programmed with

the correct code for maximum functionality, test the

component. Attempt to control a variety of the component's

functions with the remote. If some of the features of your

components 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. Different codes can provide different levels of
functionality

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. The site has set-up code list & set-up procedure to many popular brand remote controls. The site has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Set-up code list to many brand remote controls also is given. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily.

hi you need to reprogram the remote to fit with the unit there have 3 codes for remote 1 or 2 or 3 to reprogram your remote with the code indicated on your display press and hold the [3] and [ENTER/OK] buttons together for approx 5 to 10 seconds, then release

re-sync remote by pressing "enter"/"OK" while holding number "1" or "2" or "3" - the proper number should be displaying on unit as RC1, RC2, or RC3

Anytime your unit displays RC1, 2, or 3 - the remote code needs to be reset. Other messages are "chk remote n" or "set n", n being the number 1, 2 or 3. These remote codes are set in case you have multiple products that interact w/ the remote - so when operating one device the other doesn't interfere. Unfortunately, every now and then for completely unknown reasons, they can slip out of the proper code. All you have to do (if your remote is, in fact, functional) is press and hold the number on the remote that corresponds with that which displays on the unit - in your case the number 3, and hold the Enter key at the same time for about 5 to 10 seconds. This should resume operation shortly thereafter. However, you will not see any confirmation on the display as you are performing this reset. It is trial and error.
