Turning Off Interior Alarm Sensor

[Beez]

Hi!

About to take auto train for the first time. The site advises: 

Deactivate car alarm system before you drop off your car. Failure to do so may result in a dead Battery if your alarm goes off en route.

Anyone ever take the train before and had to disable the alarm? If so, any advise on how to do it? Or should I not even worry about it?

Thanks!

Just lock the vehicle with the mechanical key, the alarm won't be set. Otherwise you can turn off the interior sensor using the satellite switch menu when you turn off the vehicle.

I've done 6 ferry trips, including Hull - Zeebrugge twice and had no problems with normal locking. It seems OK, even in choppy seas
