2.7.13 Foot pedal
There is no disassembly required for the Foot pedal. The foot pedal can be replaced only.
In case of replacement:
• Connect the new foot pedal to the EVA System; use the back-up cable for pairing the foot pedal
to the System.
• The foot pedal will be automatically paired to the EVA.
• Disconnect the back-up cable.
After pairing, the foot pedal can be used in wireless mode.

2.8.1 Functional test
By start up of the EVA the system will perform a self test.
2.8.2 Safety test
Perform a safety test according to IEC60601
2.9 Testing modules
2.9.1 Laser: Power Calibration
The power indicated at the display is measured and calibrated automatically inside the mod-
ule. The power indicated at the display is the power which is available “for treatment”.
However it is important to check the power, especially if the laser is extensively used. At the
routine control, which we strongly suggest every 2nd years, it will be part of the routine.
2.9.2 Laser: Calibration of the internal power meter
Since the internal power meter is housed inside and is protected against the environment a
calibration of this power meter is not required.
However during the external check with an external power meter it will be compared by the
technician automatically.
However, if the values of the power do vary more than the +/-20% during the routine check,
the Laser has to be re-calibrated at the office of the distributor or at D.O.R.C. International
directly.
