This is a control on the front of the RX9 which allows the sensitivity to be adjusted. Taking the smaller part off allows you to plug in a lamp, etc which will come on when the alarm is triggered. Hope this helps.

No. There is only 1 button. On my system it is right click by default but you may be able to change it through your systems drivers.

Yes, there is a button on the top panel to turn the blue light on & off - very clear! Happy Holidays!

You can't take it out of the choices but you can turn on the "blue screen" so that when it goes to that input you get silence and blue screen instead of snow and audio noise...when in the tuner mode pop up the menu and go to "input"...select blue screen = "on."

The same switch-button that is used to select the speed is also the eject button when it is pushed. This could be an issue for some people since one might push down on the button in the process of selecting a speed. I haven't had any problem with it, however...

That's a good question. Not really sure. It seems to need a couple presses of the button every now and again but I'm not sure what the reason is for that

It just makes a 'click' when you switch. If "A" is down and "B" is up, then when you depress "B", the "A" button makes a click when it pops up. It isn't noisy really.

Its the button that looks like a power button with an arrow pointing up and to the left. Its located above the volume up button.

One of the buttons is to answer a call when you hear the beep that indicates that you have one. I believe one button is to disconnect a call when you are finished. I can't tell you which one is which because I just do it by feel, never look at them. Just try them out to see what they do.

The blue wire is a remote power switch for the backup camera function.The display has two video inputs, AV1 and either AV2 or a backup camera. You use the buttons on the front and leave the blue wire disconnected if you're just using the display for AV. Putting power on the blue wire (red must have power also) will turn the display on and select input 2 without pressing the power button. It also puts a CAR BACK message instead of AV2 in the corner of the display when there is no video signal.The display will turn on with as little as 3V on the blue wire so you could connect your video to input 2 (female RCA) and an I/O to the blue wire to turn the display on and off.

There's a button on the keyboard that allows you to bring up the onscreen keyboard, even while the bluetooth keyboard is on & connected.

You push the button for each lap. It's easy, though, to do it with your thumb. Just takes a second.

I agree with the answer about the blue button (next to the delete key). When "battery up" is on, it shuts everything on the base off except for the keyboard. This is a guess but a good place to start trouble shooting.
