Punch-Through Sound
Punch-through sound enables you to control the audio level of
your first or second TV, regardless of what device mode the
remote control is in.
EXAMPLE:
You have installed a second TV under SAT mode. You can
control that TV’s volume when you are in VCR mode. This
feature is installed as a default setting for a first TV.
To install this feature for a second TV:
1 Press the mode selector key to select VCR.
2 Press and hold keys 1 and 6 simultaneously -for about 3
seconds- until the green LED lights up.
3 On the keypad, press keys 9, 9, and 3.
4 Press the mode selector key to select SAT (second TV).
5 Press the power key.
– That’s it! The LED flashes twice to indicate successful set
up.
The Volume up/down keys now control the volume of your
second (SAT) TV when you’re in VCR mode.
Functional back-lighting
When you pick up the SBC RU644 and tilt it over about 60
degrees, the main keys for the device you want to operate are
automatically back-lit.
In VCR mode for example, only the main keys that are needed
to operate the VCR are back-lit.
You can choose to have all of the keys back-lit, or you can
switch off the functional back-lighting feature completely.
To back-light all of the keys:
• Press keys 1 and 9 simultaneously -for about 3 seconds-
until the green LED flashes twice.
– The functional back-lighting is now de-activated and all
keys light up when you pick up the remote control.
Pressing keys 1 and 9 simultaneously again -for about 3
seconds- will return the back-lighting to its preset functional
setting.
Note
The back-lighting turns off if you don’t move the remote control
or if you don’t press a key within 4 seconds.
