exposed to less radiation compared to when operating without. For
details on the scatter data of the device configured both with and
without the backscatter shield, please review ‘10.2.3 Scattered
Dose’.
This equipment is shipped with the backscatter shield attached (firmly
fixed), so the backscatter shield cannot be replaced by users. If it is
damaged or defective, contact your Service Representative for
replacement.
Mode of operation: Continuous operation with intermittent loading—This
equipment needs a rest time of at least 30 times the exposure time
before starting the next exposure.

the battery for about 1 day, it indicates that the battery has been fully
discharged. Contact your Service Representative for battery
replacement.
- DO NOT charge a fully discharged battery, as this may cause fire
or explosion. Be sure to replace the battery (provided by VATECH).
Batteries can be replaced by users.
When charging the battery, the exposure function is locked.
Be sure to turn off the equipment when not in use. This helps to
ensure the life of the battery.

3. System Overview
EzRay Air (Model: VEX-P300) User Manual 13
ENGLISH
3. System Overview
The VEX-P300, a portable dental X-ray system, operates on 22.2 V d.c. supplied by a
rechargeable Li-ion polymer battery pack. The portable X-ray system is an X-ray
generating device which is mainly designed for dental examination (teeth and jaw).
The portable X-ray system is composed of an X-ray generating part with an X-ray tube
including a device controller, a power controller, a user interface, a beam limiting part,
a backscatter shield, and an optional Remote Exposure Switch. The VEX-P300 is
designed to diagnose teeth and jaw through X-ray exposure using intra-oral image
receptors.
3.1 Indications for Use
The VEX-P300 is a portable dental X-ray system intended for use by a trained and
qualified dentist or dental technician for both adult and pediatric subjects for producing
diagnostic dental radiographs for treatment of diseases of the teeth, jaw, and other oral
structures using intra-oral image receptors.
3.2 Principles of Operation
X-rays are emitted when a high voltage is supplied to the X-ray tube assembly which
frees electrons from the cathode. They hit anode to produce X-rays. The equipment
acquires images by emitting X-rays continuously on the human tooth.
3.3 Intended User Profile
Considerations
Requirement Description
Education
A licensed dentist or dental hygiene, radiologist and
graduates of relevant bachelor’s degree (national
qualifications)
Knowledge
The operator must have understood:
