Here's how to adjust the volume on the 1050 no matter what device mode is selected:
Volume Punch Through

1.PRESS the device, (TV, VCR, SAT, etc.), button - RELEASE
2.PRESS and HOLD the SETUP button until the red LED flashes twice, then RELEASE.
3.PRESS 9 - 9 - 3.
4.PRESS the TNR button.
5.Two blinks.

Here's how to change the TV channels while you are in SAT mode. (If you have set your SAT input to come in through the video port on your TV)I did this because my SAT dish is set-up through the video1 mode on the TV & the on-air network channels are coming in through an antenna. Now I can surf from SAT mode & check whats on the on-air channels without changing device modes.

1.Press SETUP and hold down until the LED blinks twice
2.Press 9 9 4 (the LED will blink twice)
3.Press TV and CH+ and SAT and CH+ (the LED will blink twice)
4.Press SETUP and hold down until the LED blinks twice
5.Press 9 9 4 (the LED will blink twice)
6.Press TV and CH- and SAT and CH- (the LED will blink twice)
7.Press SETUP and hold down until the LED blinks twice
8.Press 9 9 4 (the LED will blink twice)
9.Press TV and INPUT and SAT and INPUT (the LED will blink twice)
