1 Introduction
Thank you very much for purchasing a Garz & Fricke product. Our products are dedicated to professional use
and therefore we suppose extended technical knowledge and practice in working with such products.
The information in this manual is subject to technical changes, particularly as a result of continuous
product upgrades. Thus this manual only reflects the technical status of the products at the time of
printing. Before design-in the device into your or your customer’s product, please verify that this
document and the therein described specification is the latest revision and matches to the PCB
version. We highly recommend contacting our technical sales team prior to any activity of that kind.
The attached documentation does not entail any guarantee on the part of Garz & Fricke GmbH with
respect to technical processes described in the manual or any product characteristics set out in the
manual. We do not accept any liability for any printing errors or other inaccuracies in the manual
unless it can be proven that we are aware of such errors or inaccuracies or that we are unaware of
these as a result of gross negligence and Garz & Fricke has failed to eliminate these errors or
inaccuracies for this reason.
Garz & Fricke GmbH expressly informs that this manual only contains a general description of
technical processes and instructions which may not be applicable in every individual case. In cases of
doubt, please contact our technical sales team.
In no event, Garz & Fricke is liable for any direct, indirect, special, incidental or consequential
damages arising out of use or resulting from non-compliancy of therein conditions and precautions,
even if advised of the possibility of such damages.
Before using a device covered by this document, please carefully read
Annex G-1 Warranty hints
Annex G-2 Application notes
Embedded systems are complex and sensitive electronic products. Please act carefully and ensure
that only qualified personnel will handle and use the device at the stage of development. In the event
of damage to the device caused by failure to observe the hints in this manual and on the device
(especially the safety instructions), Garz & Fricke shall not be required to honour the warranty even
during the warranty period and shall be exempted from the statutory accident liability obligation.
Attempting to repair or modify the product also voids all warranty claims.

2 Safety Hints
Please read this section carefully and observe the instructions for your own safety and correct use of the
device. Observe the warnings and instructions on the device and in the manual. Garz & Fricke embedded
systems have been built and tested by us and left the company in a perfectly safe condition.
In order to maintain this condition and ensure safe operation, the user must observe the instructions and
warnings contained in this manual.
I. General handling
Don’t drop or strike the unit: The PCB, display and/or other parts might be damaged.
Keep away from water and other liquids, the unit is not protected against.
Operate the unit under electrical and environmental conditions according to the technical
specification.
The electrical installations in the room must correspond to the requirements of the local (country-
specific) regulations.
Take care that there are no cables, particularly power cables, in areas where persons can trip
over them.
Do not place the device in direct sunlight, near heat sources or in a damp place.
All plugs on the connection cables must be screwed or locked to the housing.
Repairs may only be carried out by qualified specialist personnel authorized by Garz & Fricke
GmbH or their local distributors.
Maintenance or repair on the open device may only be carried out by qualified personnel
authorized by Garz & Fricke GmbH which is aware of with the associated dangers.
II. LCD and touch handling
If equipped with, the soft surface of a resistive touch screen is not suitable for use with stencils
and/or other devices for touch operation. There are special plastics pens available in commercial
shops. A projective capacitive touch screen might be protected by a heat strengthened glass or
acrylic or polycarbonate cover lens. These are dedicated for use with finger tips. There are very
special pens available which might work with a PCT touch.
Protect the LCD/touch/cover lens against scratches and sharp edges. The warranty does not
cover pixel failures resulting from non-compliant handling.
Clean the LCD/touch/cover lens with a soft cotton cloth with alcohol. Don’t use organic solvents,
acid or alkali solutions.
Water drops, finger fat or any similar fouling should be removed immediately from the LCD,
cover lens and metal frame to avoid any staining.
III. Electricity
The embedded systems may only be opened in accordance with the description in this user’s
manual for
replacing of the (rechargeable, where applicable) lithium battery and/or
configuration of interfaces, where applicable
These procedures have to be carried-out only by qualified specialist personnel.
When accessing internal components the device must be switched off and disconnected from the
power source.
When purchased core or basic versions without protecting back cover, don’t touch the PCB
directly with your fingers. Especially these products need to be handled very carefully.
Don’t operate or handle the unit without typical ESD protection measures, such as ground
earthing.
Operate the unit according to the technical specification only.
IV. Damage or permanent malfunction
It must be assumed that a safe operation is no longer possible, in case
the device has visible damage or
the display is dark or shows strange pattern for longer period
the device doesn’t react after a reset
In these cases the device must be shut down and secured against further use

3 Product Introduction
This document is applicable for hardware revisions 1.0 or later of the NESO LT SERIES and thereon based
customized variants. Please note that customized variants might possibly not support all features listed herein.
Please find the hardware version grid in Annex B:
Product introduction 3.1
NESO LT is an Embedded System to be used as human machine interface (HMI) in various applications.
Please refer to G-2 Application notes for further information. The system is equipped with a large number of
industrial interfaces. A wide variety of options is available as well.
Type plate and device information 3.2
For service and later identification of the device, the type plate contains important information, such as article
numbers (linked to the PCB rev.), the order code and model name (which is valid for all PCB rev.) and the
serial number, that identifies the exact device.

Backlight lifetime is dictated by the LCD manufacture´s specification. Backlight lifetime is the approximate time at which
the brightness decreases to half of its original brightness. Reduction of brightness due to backlight lifetime is not
considered as failure. It is a natural aging of all electronic components.
3
Electrical products use the industrial standard term Mean Time between Failure (MTBF) as a statistical prediction of the
elapsed time between failures in a large population of systems.
The MTBF of all Garz & Fricke HMI products shall be 50,000 hours
A failure is anything that causes the product not to function to its specifications
Reduction in brightness due to backlight lifetime is not a failure
If the LCD used in the system exceeds its pixel defect specification it is considered a failure
