How do I code search my RCA model RCR311W Remote

The Auto Code Search and Entry Method enables the remote
to automatically search through all the codes in the Code Lists
for the one that operates your component.
Note: The Auto Code Search method may take a
long time because the remote searches through all of the codes
in its memory for the code that operates your component.
1. Manually turn on the component you want the remote to
control (TV).
2. Note: If you press an invalid key during the Auto Code
Search, the remote does not respond and the illuminated
ON•OFF key does not blink.
3. If you do not press a valid
Auto Code Search key (TV), the search times out
after two minutes. When the search times out, the illuminated
ON•OFF key blinks four times and turns off. The last
programmed code under that component key is retained.
4. Press and hold the component key
(TV). The illuminated ON•OFF
key turns on and remains on.
5. While holding the component key
down, press and hold the ON•OFF
key. The illuminated ON•OFF key
turns off.
6. After holding down both keys for
three seconds, the illuminated
ON•OFF key turns back on.
7. Release both keys. The illuminated
ON•OFF key remains on.
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.
8. Press and release the PLAY key,
then wait five seconds to see if
your component turns off. If your
component does not respond,
continue to press the PLAY key
every five seconds until your
component turns off. Each time you
press the PLAY key, the illuminated
ON•OFF key blinks and a block of
10 codes are sent to your component.
This process continues until all of
the codes in the Code Lists have
been searched. (If your component
has not turned off after all codes have
been searched, the illuminated
ON•OFF key blinks four times and
turns off. The Auto Code Search
Entry method is exited.)
9. When your component turns off, you
know the correct code is in the last
block of 10 codes sent. Press and
release the REVERSE key. Wait two
seconds to see if your component turns
on again. If your component does not
respond, continue to press the
REVERSE key every two 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 key after your component
responds, press and release the
FORWARD key. Then, wait two
seconds to see if your component
turns off again.
10. 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.
You must press the STOP key
to save the code or the correct code
will not be stored!
11. 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.
