Viper 690XV, Remote transmitter

Can anybody tell me how it works?:

- in the installation manual it says, that the remote transmitter can either be programmed to standard configuration (ar and disarm with two separate keys) or to single button configuration (arm and disarm with only one key); but it's not described, how I can switch between these configurations

- in the insatllation manual it also says, that a lot of individual key combinations for different functions can be assigned to the butoons of the remote transmitter; how can I do this?

Thanks for your help
