WARNING: PRECAUTIONS WHILE USING LASER CENTRING
DEVICES
Also if the laser devices, according to IEC 60825-1, are in Class I:
•
It is necessary an adequate illumination in the room.
• Do not look into the output windows of laser centring units.
•
Do not stare at the reflections of laser pointers.
• Instruct the patient to keep his/her eyes closed as long as the laser
pointers are active.
•
Before starting an examination, the patient must remove earrings,
glasses, necklaces and whatever else could reflect the laser beam or
be impressed on the radiographic image.
• Do not clean the openings of laser centring devices with tools that
could modify the optics. Necessary cleaning must be performed only

WARNING: PRECAUTIONS DURING INSTALLATION AND SERVICE
INTERVENTIONS
• Please take highest care while mounting the column at the wall and
strictly follow the instructions listed in this manual.
• Before removing the covers of the column, or before removing the
covers of the Generator board (A10), disconnect the power supply to
the device, both switching the main switch and the magneto-thermal
differential off, and wait at least 2 minute.
• When the device is supplied without the above mentioned coverings,
pay the highest attention since high voltage is generated in the
supply unit, and the voltage is at about 400 Vdc on the Generator
board. This is indicated by the green LED H1. Should the LED be off
and before any other intervention, disconnect the device from the net,
wait at least 2 minute, then check the fuses F1 (10AF) in the supply
unit, or F2 (5AF) on the Generator board (see circuit diagram).
• Each intervention must be performed after having disconnected the
device from the supply net and after LED H1 is OFF. It is anyway
advisable to wait at least 2 minute from the LED's switching off.
•
The system construction do not allow the repair of
faulty/damaged parts, that must be replaced using original spare
parts supplied by Villa Sistemi Medicali. Only trained personnel
is authorized to make service interventions on the unit,
