The user must remove the key after the treatment.
Remote interlock
The ability to fire the laser can be made dependent on the

happy to assist, if you wish to connect the laser to a
remote interlock.
If the instrument is not connected to a remote interlock, a
shorting plug which bridges the respective contacts must
be inserted in the interlock socket (The device is delivered
with the shorting plug inserted.).
Monitoring of therapy

beam energy
energy is outside the pre-defined range.
Safety monitoring
The electronic systems monitor various functions and
values. If any of these values are outside the permitted
range, the system prevents the laser from being fired.
