Introduction●Hand Switch
The hand switch enables quick start/stop operation.
This is very useful if you often make the start/stop operation and/or you work away from the powerpack●Mounting Handpiece Identification Resistor
The handpiece mounts a handpiece identification resistor corresponded to the handpiece identification function
on Minimo One Series Ver.2 powerpacks.
This function optimally controls rotation speed and torque of the handpiece.
●Removable Handpiece
The motor and head part are removable. So, you can select motors and heads for your own purpose.
●Curl CordAs the curl cord is elastic, it does not interrupt your work.
