When wall mounting the scanner’s base, be careful to respect measurements
indicated to drill holes for the wall mount.
•It is recommended to use wall anchors and threaded screws with an 8mm
(5/16th inch) head diameter.
•A 4-5mm (3/16th in) distance between wall and bottom screw head is
recommended.
Caution: If the docking base is not properly installed there is a
possibility of the base falling and damaging the scanner.
IMPORTANT: Vatech is not responsible for accidents or damage
caused in the event the scanner falls.

Page 15
3.2 Connecting the EzScan
To install and connect the EzScan Scanner:
STEP 1. Place the docking base on a flat, stable surface and
place the EzScan handpiece securely on the base.
STEP 2. Connect the AC/DC power adapter cable to the docking
base (the connector socket is located underneath the
base of the scanner).
STEP 3. Connect the provided USB 3.0 cable to the docking
base (the connector socket is located underneath the
base of the scanner).
STEP 4. Connect the other end of the USB 3.0 cable to the
computer.
WARNING: Using a USB cable other than the one provided may
result in system malfunction or reduced performance.
WARNING: Make sure you use the 5.0V 4A power adapter
provided. Failure to do so may result in damage to the scanning
device.

Page 16
User Manual
STEP 5. Connect the adapter block provided to a power outlet.
IMPORTANT: Connect to Power Supply before Scanning!
If your laptop computer is not properly
connected to a power outlet, the following
message will appear:
In this case, please connect your laptop to the
power supply before proceeding to use to
scanner.
IMPORTANT: When using a desktop computer, it is strongly
recommended to plug the USB cable to a USB port located at the
back of the computer; not doing so may result in system
malfunction or reduced performance.
DO NOT plug the USB cable into an intermediate hub.
IMPORTANT: If using a laptop computer, make sure the power
supply is connected to a power outlet and not running on battery
power. Failure to do so will mean that the scanner will not have
sufficient power to produce images.
On laptop computers, battery settings in Windows should be
configured to high performance mode only, with no battery
saving option (Settings/System/Battery).
IMPORTANT: Make sure to use a USB port that is compatible
with USB 3.0 (SuperSpeed), usually indicated by this symbol:
not doing so may result system malfunction or reduced
performance.
