Why does my pen make noise when I write?

Last Updated: Jan 14, 2015 03:36PM PST
Equil Smartpen 2 generates a soft buzzing sound for about 30 seconds when the pen is first turned on. This sound is not harmful in any way, and it tells you that your Equil Smartpen is working properly. After the initial 30 seconds, the buzzing will stop and the pen will not make a noise. 

When writing or drawing with Equil Smartpen, it is normal to hear a soft buzzing from the pen tip. This buzzing sound is an indication that the pen is powered on and sending information to the receiver.
