Viper 791 and multiple cars

Hello all,

I just had 2 Viper 791xv installed in a suburban and g35. They set up the remotes so that the lock button is arm/disarm and the unlock button is the aux (for silent arming and trunk release on the g35). The bottom two buttons are the same for the other car. Holding top 2 simultaneously remote starts one car, holding bottom two remote stats the second.

Here's the question...Since these are responder systems, it seems they get "confused" when arm/disarming when the 2 vehicles are together. The functionality of the alarms is fine...they do what they're supposed to, but if I have the g35 locked and armed, and then unlock the suburban, the remote tells me the alarm is unlocked. I understand this, and it's no big deal...The question I have (finally), is that when I push the buttons on the transmitters, I get 3 short beeps on arming and 7 beeps on disarming...But, it only happens when the vehicles are nearby. When I arm/disarm at work for instance (no suburban nearby), I just get the single and double beeps from the transmitters as normal. Any idea what the extra beeps are for?

Many thanks!
