Telling the Linn sound systems apart

[gpb1]

Is there any wasy way to determine which sound system (128w, 260w or 950w) is fitted in a DB9? Speaker location? Something in the settings?
Want to confirm what the seller is telling me.
Thanks

Just turn it on and look at the display -- it tells you what's installed

Doh! ok, i think i can cope with that.
Thanks
