2.1. Warnings
This device has not been designed to be used in environments where
vapours, anaesthetic mixtures flammable with air, or oxygen and nitrous
oxide, can be detected.
Do not let water, or other liquids, into the device, as this could cause
short-circuits and corrosion.
Before cleaning the device, be sure the that main power supply has been
disconnected from the equipment. Pushing the ON/OFF button on the
basement of the equipment, it mustn't switch on.
Wherever necessary, instruct the customer regarding the following:
• to use the proper accessories, such as the leaded aprons, to protect
the patient from radiations
•
while performing the radiography, no one, apart from the operator
and the patient, must remain in the room
• to clean and disinfect, when necessary, all parts that can be in
contact with the patient
• to replace the bite or the bite protective sleeve and the ear-
centring devices after the use.
Rotograph EVO has been built to support a continuous operation at
intermittent load; therefore please follow the described use cycles to
enable the device to cool down.
Rotograph EVO must be switched off while using devices such as
electrical lancets or the like.
Never try to rotate the moving arm manually when the unit is
switched on, to avoid permanent damage to the unit.
Movement is only possible in case of Error 362 because motors are
disabled to permit the patient exit.
The authorised technician must be sure that the unit is disconnect from
the main power supply before removing the coverings.
The high frequency generator, located on the rotating arm, can hold
dangerous voltage for more than 2 minutes from the power off.
Though the X-ray quantity supplied by dental X-ray units is quite low
and distributed on a small surface, the operator must adopt the
precautions and/or fit protections for the patient and himself, during the
execution of a radiography. It is advisable to control the X-ray emission
from a protected area, by means of a remote control. In case it is
necessary to operate near the patient, please stay as far as the cable of
the remote control allows it, or at least 1,5 m (4.92') both from the X-ray
source and from the patient, as shown in the pictures below.
