No booklet with mine, just a little info card. So here's what it says:-
META M351 Alarm/Immobiliser
Current consumption
Armed 10mA
Disarmed – 6.5mA
Passive Arming
The immobilisation circuits only will arm automatically 45 seconds after the ignition is switched off. This is confirmed by 2 x audible signals. The LED will also begin to flash
De-Activation
Pressing the transmitter for 1 second will switch the complete system off. If the ignition is not switched on the immobilisation will automatically re-arm in 45 seconds
Alarm and Immobilisation Arming
With the system completely disarmed, pressing the transmitter for 1 second will arm the alarm and immobiliser. This is confirmed by 2 audible and visual signals. The LED will begin to flash
Self-Test
If any of the alarm trigger circuits are active during the arming period, the alarm will confirm this by 4 x audible signals. Disarm the system, check the machine is secure and re-arm the system
Alarm Test
During the first 25 seconds of the alarm being armed, the system can be tested by operating any of the alarm circuits. Confirmation that the alarm has received a trigger signal is shown by a 0.8 second activation of the alarm siren and the hazard lights
Arming Mode 2
If required it is possible to arm the system without the inclusion of the movement sensor. Press and hold the transmitter button. The normal arming signal will be followed within a couple of seconds by 2 x audible signals. On resetting the system the movement sensor will be automatically re-activated
Location
With the system disarmed, pressing the transmitter button for 6 seconds will activate the siren and hazard lights for 14 seconds of operation, after which the system will be placed in the arming mode 2
Alarm Warning
If the system is triggered, on disarming there will be the normal disarm signal followed by a very short audible signal. The LED will flash as follows:-
Movement sensor – 1 flash every 6 seconds
Switch sensor – 2 flashes every 6 seconds
Accessory Loop/Battery back up – 4 flashes
Ignition sensor – 8 flashes
WTF is valet mode? Mine's lucky to get a wash

I'm guessing you mean it can be moved but not started? That'll be Arming Mode 2
