Hi Again

I should of added this on my other post but its not really related.

When I mount the key on my RXP I get a long beeeeeeeeep for 2-3 seconds from the alarm sounder before I get the beep beep to say its ready. Well I only got the beep beep on my RX?

I've done the 5 presses of the set key to check for codes and its all clear, I thought it may of been low fuel indicator as that came on at same time but its full now and the low fuel indicator has gone so its not that...

any ideas
