Preface
About the terminal
The GT series of data collection terminals has been designed for various applications including
Time and Attendance in both the commercial and retail sectors, where low cost, flexibility and
ease of installation are essential factors.
The terminal incorporates a flexible, modular hardware design which supports different reader
technologies such as biometric, proximity, barcode and magnetic as well as enabling power
supplies and ancillary input/output modules to be easily added.
The GT series of terminals run an advanced Android operating system offering unsurpassed
functionality with flexibility giving a rich user experience for data collection solutions.
The ability to manage the software after deployment is incorporated as a fundamental function of
the system. Everything from a complete operating system flash image update to a change in
application program parameters can be downloaded over the Internet or uploaded via USB
memory stick.

Preface
Certifications
The GT8 has been certified for use in the following markets:
Europe CE Certification
USA FCC, UL 62368-1
In addition, the terminal has been certified to comply with the requirements of the CB certification
authority which may meet compliance requirements in their member countries. For further
information regarding CB certification please see www.iecee.org/dyn/www/f?p=106:40:0, or
discuss with Grosvenor Technology’s professional services team.
If the GT8 is intended to be used in countries other than those listed above, please contact
Grosvenor Technology’s professional services team to discuss how we can assist with
certification.
Battery Life
The GT8 terminal is fitted with a Lithium-Ion battery which typically has a service life of between
two-three years. In order to ensure the continued reliable operation of the back-up battery function
we recommend regularly checking the condition of the battery and replacing it when it has reached
the end of its service life.
The GT8 is also fitted with a button cell type battery on the main PCB to maintain the real-time
clock (RTC) of the device when power is removed. This battery typically has a service life of
around 10 years. The battery should only be replaced by suitably qualified engineers and care
should be taken to avoid damage to the PCB caused by ESD (ElectroStatic Discharge).
Replacement batteries must be of the same type as the original, and the old battery should be
disposed of in accordance with local regulations.
Care should be taken when recycling the terminal to ensure that the batteries are removed and
recycled in accordance with local regulations/legislation.
Maintenance
The GT8 terminaldoes not require any regular maintenance during its service life.
It is however recommended that periodically, once every six months, the condition of the battery
should be checked to see if there are signs that it’s reaching the end of its life. Occasionally, the
battery may start to swell towards the end of its life, if this is noticed, the battery should be replaced
(Part Number: EM-BB-2HR-A).

Preface
Cleaning
Cleaning of the outside of the terminal can be undertaken at intervals appropriate to the
environment that it is being used and the frequency of use. In all cases it is recommended that the
surface of the terminal is wiped with a lint free cloth that has been dampened with up to 70%
isopropyl alcohol. We do not recommend spraying liquids directly onto the surface of the terminal
as this could potentially cause damage to the electronics. Particular care should be taken when
cleaning the display and biometric devices to prevent damage.
Installation Safety
The GT8 terminal should be installed in accordance with the instructions documented in this User
Guide. The terminal should be installed in compliance with any Health and Safety legislation and
it is recommended that any electrical or network connections to the terminal are undertaken by a
suitably qualified engineer.
The GT8 terminal is designed to be installed indoors only with a normal ambient operating
temperature between 0-35 °C (32-95 °F).
Care should be taken when installing the terminal to ensure that it does not present any possible
hazards to people or property within its vicinity. The terminal should be installed at a height that
ensures compliance with any local disability legislation.
WEEE
In accordance with EN 50419, the terminal must be disposed at the end of its life by returning to
a designated recycling organisation for waste electrical and electronic equipment as defined
within the WEEE directive. The terminal must not be disposed of in normal domestic waste.
Batteries should be carefully removed from the terminal prior to disposal taking care to prevent
short-circuits, crushing or damage to the battery housing.
