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. 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.
III. 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
