How do you scan for codes with universal remote 15-2147

I pulled these instructions directly from the manual:

1. Press TV once.
2. Press and hold P until the red LED blinks twice,
then release.
3. Enter 9 9 1. The LED blinks twice.
4. Aim the remote at the TV and press Power. The
remote sends IR codes from its library to the
selected device, starting with the most popular
code first.
5. If the TV responds, go to step 6. If the TV does
not respond, press CH+. The remote will try the
next code. Continue until the TV responds.
NOTE: Press CH- to try the previous code.
6. To lock in the code, press P once. The LED
blinks twice.
7. To search for other device codes, repeat steps 1
to 6, substituting the appropriate key for the
device.
