6 OPERATION OF THE TOOL RADIO DEVICES
Wireless connection with Bluetooth, WiFi and GPRS
technology
The wireless connectivity with the Bluetooth, WiFi and GPRS
technology is a technology that supplies a standard, reliable
method to exchange information between different devices, using
radio waves. Adding to the TEXA instruments, many more
products use this technology, such as cellular phones, portable
devices, Computers, printers, photo cameras, Pocket PCs etc.
The Bluetooth, WiFi and GPRS interfaces look for compatible
electronic devices according to the radio signal they emit and
establish a connection between them. TEXA tools select and only
prompt you with compatible TEXA devices. This does not exclude
the presence of other sources of communication or disturbance.
THE EFFICIENCY AND THE QUALITY OF BLUETOOTH, WiFi
AND GPRS COMMUNICATION MAY BE INFLUENCED BY THE
PRESENCE OF RADIO DISTURBANCE SOURCES. THE
COMMUNICATION PROTOCOL HAS BEEN DEVELOPED TO
MANAGE THESE TYPES OF ERRORS; HOWEVER, IN THESE
CASES COMMUNICATION MAY BECOME DIFFICULT AND
CONNECTION MAY REQUIRE SEVERAL ATTEMPTS.
SHOULD THE WIRELESS CONNECTION BE CRITICAL AND
COMPROMISE A REGULAR COMMUNICATION, THE
SOURCE OF THE ENVIRONMENTAL ELECTROMAGNETIC
DISTURBANCE MUST BE IDENTIFIED AND ITS INTENSITY
MUST BE REDUCED.
Position the tool so that the radio devices it is equipped with can
work properly. In particular, do not cover it with any shielding
materials or with any metallic materials in general.

required in order to recharge the vehicle battery.
The activation date, the actual availability, the
type, the cost and the procedures regarding the use of
the Pass-Thru service(s) are specifically determined by
the individual manufacturer; costs, performance, and
procedures may therefore vary independently from what
TEXA S.p.A establishes.
TEXA S.p.A. is not under any circumstance liable
for repair and maintenance work carried out on vehicles;
by using the technical information and/or the service(s)
offered by the specific websites of individual
