3. Delivering Treatment
a. Check copies of settings data.
Before firing in User mode, the copies of the duplicated settings data will be compared, and if
the copies are not identical, the system will display an error message and not fire.
b. Distinctive Audible and Visible Indications.
Before firing in User mode, the system will give a distinctive audible and visible indications as
to which kind of laser will fire (i.e., Holmium or Neodymium).
c. Starting with Holmium Lasers.
When starting a treatment using the Holmium laser, the system will warm up the laser rods in
use by firing a sequence of pulses with the shutter closed. When the sequence is completed,
the system will open the shutter and proceed to fire in Treatment mode.
When the pulse rate is such that the system is required to fire fewer than the number of Hol-
mium rods available, the system will use a different combination of rods each time it starts fir-
ing.
d. During Firing.
While the system is firing in Treatment mode, the system controls the outputs of the individ-
ual lasers using a feedback from the main energy channel, and will monitor the outputs using
the safety energy channel. The system will stop firing and display a message if pulse energy as
indicated by either channel exceeds the specified limits.
e. Tropic Mode.
When firing in Treatment mode using the Holmium laser, the system will reduce the laser
energy setting if the system is firing at greater than 60W and the coolant temperature rises
above 40• C. The energy setting will be reduced by 4% per degree C by which the coolant tem-
perature exceeds 40• C. The values of pulse energy at which pulse energy errors are set will be
adjusted to correspond to the changed pulse energy setting.
f. Limp Model.
If a given laser rod generates more than 4 low-energy errors after power is turned on, the sys-
tem will consider that a rod has failed.
