Standby control

[PianoSam]

Hi,
Can anyone tell me how I can control the time that my herald 100 takes to go into standby. I want to ensure that if a user leaves the device in a cab/pub/office that it enters standby within 10 seconds.

Is this possible?

Many thanks,
Sam.

Settings -> System -> Power Supply -> Advanced
