avantguard 5.5 , concept 650 siren tone

Hi all I now have both these alarms Installed avantguard 5.5 in my Is200 turbo Concept 650 in a Nissan Stagea NA now the installer that set my Avanguard unit up changed the alarm tones via the keyfob under the installer section, now i have hunted high and low but cant work out which section he did it have spoken to previous owner and they remember him saying its not including in the UK guide and is a hidden feature. does anyone know how this can be done via the remote the reason for this is i want to do the same tone outlet on my new alarm so both match as it will then stand out should either alarm go off, where ever i am...

PM me with your email address I'll send you the install sheet for the US AG 5.1 which shows you how. It's the same processor as 650 ll and 5.5
