By default, the Time Warner UR5U-8780L-TWP remote control when in CBL mode assumes the volume you want to control is the TV’s. That makes sense for most people who don’t have a separate surround sound system. But for those of us who do have a surround sound system it’s quite an annoyance. I have my Bose programmed to the AUX button of the remote so I have to press AUX every time I want to change the volume, and press the CBL button again to switch channels.
Re-reading the manual I noticed a section on how to program the volume. By following the directions below I was able to program the volume control to control the AUX device, not the TV. When in CBL mode, and I press the volume control, the AUX button will light up, but I will stay in CBL mode to continue changing channels. Perfection!
STEP 1. Press the [OK/SEL] button and [CBL] button simultaneously for three seconds. The device LED will turn on for 30 seconds. The next step must be performed while the LED is on.
STEP 2. Press the [VOL UP] button. The device LED will blink.
STEP 3. Press the [AUX] button. The device LED will blink twice to confirm the programming.
