Back lighting for my viper 479v remote

You have to go in to the proramming mode of the remote to change this feature. you can access this by holding all 4 buttons on the remote at the same time. (or if you have the P button on the back you can hold it down by itself) you will hear 2 long beeps confirming the programming mode. at this time, you can change the settings by pressing 1 of the 4 buttons., each button will change a different function.

in no order------
1. Beep/vibrate or both
2. page or not to page
3.back light
4. hood, truck, or both

the remote will give 2 long beeps when it exits the programming

I got the Problem that my pager-function doen't work. I try it like the Manual saying (*-Button) but the two ways that gives doesn't work.

- Start the Programmmode while Pressing "P" on the Backside.
- Press the "STAR-Button or Panic-Button (Orange Key) on the Sender"
it Beeps 2 Times. (i try it again with 1 beep as reponse again)
i Wait 5 Seconds
it beeps 2 long times

i try the Responder, Activate the System, disarm the System. But the Pager don't change the state or receive any Signal.
The Transmitter is working perfect! No Problems to control the Viper 690XV.

What i do wrong?

Is there any hidden Feature or needable Programming in the Viper 690XV-Brain?

Thanks alot for any helpful Answer :)
