This manual is updated to the product status it is sold with, to guarantee

the user an adequate reference for equipment use and any aspect
connected with use safety. The manual may not reflect any product
variation without impact on operating procedures and use safety.

The intraoral radiographic ENDOS AC/ACP, produces high quality

dimensions of the focal spot.
ENDOS AC/ACP is exclusively intended for the execution of intraoral
X-rays.
The equipment has the following features:
• Very good quality X-rays pictures
• user friendly
• ergonomic design.
The equipment is controlled by a microprocessor that makes it possible
to reproduce exposure times and is composed of the following parts:
• Timer: ENDOS AC or ENDOS ACP equipped with wall plate
• Extension arm (30 cm, 60 cm or 80 cm for wall version)
• Scissors arm (DP)
• Tubehead 70 kV 8 mA – X-ray tube with grid.
The purpose of this manual is to provide the user with instructions that
will allow him to run the equipment safely and efficiently.
The equipment must be used according to the procedures in the manual
and never for different purposes from the ones for which it has been
designed.
