I recommend you all read page 44 of the Owners Handbook, where arming the alarm is clearly explained.

However, in a nutshell:
One press on the remote partially sets the alarm, allowing you to leave a window open and the mother-in-law in the car while travelling on a ferry for example.
Two presses of the remote activates the full alarm.

All the light flashing which some seem concerned about, is mealy conformation as to which alarm setting you have chosen. The flashes explained on page 44 confirms with my earlier post. If yours dont, you gotta problem  2007 Freelander 2 HSE TD4 Manual with Premium Pack & Moonroof.

Yep, as you'll see in my posts, I know what the manual says and how things are meant to work...

The point of my post was that I don't get the two flashes and was questioning if the two flashes are merely the the first and second single flash or a distinct two flash after the initial single flash...  FL2 TD4 XS manual, XS style pack, Martinique Blue

and
My query is that the manual says that on two presses you'll get two flashes of the indicators to inform you that it has been double locked. When I press the lock button a second time within three seconds of a first press I just get another single flash. I'm wondering if the two flashes they refer to are both single flashes together or an additional double flash after the initial single flash...

We have a new family member:
So we have been trying to unravel the volumetric sensor issue.
I have left the drivers window down and tried one press or two presses.

No matter how many presses that I use, or how long I wait, I cannot activate the alarm by leaning in through the open window. I think that the alarm may be faulty ?

Remember to leave it for 30s or so before you try it with the volumetrics on. Mind you it might not set properly if it detects that the windows are open.. not sure..

Try locking it up and then smash a window  09MY FL2 Td4 XS, Style Pack, Privacy Glass, Martinique Blue.. oh so very blue..

I have waited ages and the movement sensors don't work. I have closed the windows and it won't work. I have sat in the back seat, thinking that the seat sensors stop activation... and it wont work. When I have time, I must visit the dealers, but that have all folded near me and I have a very long drive for a trivial problem

I hate wasting time with things like this

Interesting read - but I wouldn't get too hung up about it without first checking whether the Handbook is correct re the number of indicator flashes you are supposed to get. I only get one on second push of fob button within 3secs.
Remembering issues with my old Freelander 1 and its satnav. Handbook stated to push TP and station memory button 1 or 3 together to reset unit. Never did work - then found answer on Google which read "TP and station butons 1 and 3 together". Worked a treat - so handbook despite being at the end of the Freelander 1 production run as still incorrect with no revsions addendum. So handbooks CAN be incorrect or its explanations of certain workings better presented.
