Q: Can I use Oracle to mix a 900Mhz video receiver with a 2.4Ghz video receiver?
A: Yes. Some folks claim that this is the ultimate in diversity methods. Keep in mind that your
video camera will probably need to be “buffered” with a video amplifier when it is connected to
the input of the two RF transmitters.

Q: I am not able to reliably toggle the video sources when I use the manual switching mode.
When I press the pushbutton switch it does not seem to work. What is wrong?
A: To toggle the video sources you must briefly tap the pushbutton switch. Do not press and hold
it. This is because longer button presses are reserved for the low battery alarm silencing feature.
