Below are the instructions and the "extended function codes" the remote folks sent me. Haven't tried them, and not sure all make sense. Perhaps those more skilled at this can educate me.

Instructions for inputting advanced codes

1. Find the function you wish to duplicate. The functions should be labeled the same as they appear on the original remote control for your device. The
3-digit number to the left of each function is the code you will likely use (ex. TV code 054--function code 497 is "Sleep")

2. To use the advanced functions, tap the P button one time, then enter the code for the function you wish to use. For example, on a TV working on code 054, you would tap P followed by 497 to activate the "Sleep" feature.

3. You may also program some of these functions directly onto the universal remote control. This feature is useful for frequently-used functions that are not already preprogrammed on the remote. To use this feature, just follow the instructions below.

4. First press the device key that you wish to program. Next, hold the P button until the remote blinks twice, then press 9-9-4. Now tap the P button, followed by the 3-digit code for your desired function. Finally, press the button that you would like to assign for this function. It's best to use buttons that do not already perform functions in the mode you are using (ex. the PLAY button can be used in the TV mode since your TV does not use play for anything else.)

5. After a button has been reprogrammed, you can still access its original function by tapping the P button first. However, if you need to reset a button on the remote to the original function, just press "P" (wait for two blinks)-9-9-4-BUTTON-BUTTON."

PROGRAMMING EXTENDED FUNCTIONS: (key setup)

1. Tap the DEVICE key
2. Hold down P until the red light blinks twice - release
3. Press 9-9-4
4. Tap the P for one blink and release
5. Enter the 3 digit advanced function code (see below)
6. Tap the DESIRED key...the red light should blink twice.
