Selecting video/audio inputs using with the KD-CSW4x1
On the front of the KD-CSW4x1 there is a pushbutton with a row of blue LED indicators. Each LED
corresponds to a separate video/audio input. To select a specific A/V device (input),simply push
the button repeatedly until the LED indicator for the desired input is lit. All video and audio signals
connected to that input are automatically sent to the output. Remote selection and switching of A/V
inputs and outputs with the KD-CSW4x1
(IR) Remote Control.
You can operate the KD-CSW4x1 using the supplied infrared (IR) remote control.
By pressing R1 and then one digit on the IR remote control, you go to the desired
input. The digit you enter corresponds to the desired video/audio input (1-4). For
example, if you wished to connect a DVD player on input 4, you would depress
the key 4. When the R1 key is pressed, the blue input LED indicators on the front
panel will blink until a desired input number is selected. If you prefer, you can
press R1 and also use the CH+ and CH- keys on the IR remote control to step
through and select an input.
R3 Optional Mode of Operation.
The KD-CSW4x1 may be located where other Key Digital
™
products are being
used. Since the KD-CSW4x1 shares some remote commands with other Key
Digital
™
products, it is necessary to press the R1 button before entering a remote
command. If you do not have any other Key Digital® equipment nearby, you can
set up the KD-CSW4x1 to not require the use of the R1 button before you select
an input. You do this by pressing R3 for 5 seconds. When you press R3, the
blue LED input indicator on the KD-CSW4x1 will blink. Keep pressing the R3
button until it stops blinking. You can now control the KD-CSW4x1 input selector
without pressing R1 first. If you want to go back to the mode where you press
R1 first, press R3 again for 5 seconds. Even if you are in the R3 optional mode,
you can still press R1 first if you wish.
