A lesson in Norwegian

I came across this in the manual for the baby monitor we purchased:

After reading this important bit of information I said to myself, "Self, what is a 'dult'? How exactly does a dult provide supervision?"

I had Carl look up "dult" on Dicitonary.com and this is what came up:

http://dictionary.reference.com/browse/dult

nudge [nadʒ] noun
a gentle push usually with the elbowExample: He gave her a nudge.

Norwegian:
dult, dytt

So apparently a dult is Norwegian for a nudge. I'm still confused as to how a dult provides supervision....

FYI, "Printed in China" is written on the back of the manual. Just one of the many giggles I've had on behalf of foreigners writing instructions manuals.
