Does it emit signals like cell phones

Answer

It communicates over bluetooth. So it emits signals over those frequencies.
However it only sends out signals for a short time after the alarm is set and when the alarm goes off, for the rest of the night when you are wearing it the transmitter goes to sleep.

Personally I think that the signals are quite minor compared to your phone and you will have to have your phone in the room to turn the alarm off on the Lark when you wake up.
