Global warning
The manufacturer cannot be held responsible in case of non-compliance with the
following recommendations or incorrect use of the terminal.
General precautions
Do not attempt to repair your terminal yourself. The manufacturer cannot be held
responsible for any damage/accident that may result from attempts to repair
components. Any work carried out by non-authorized personnel will invalidate your
warranty.
Do not expose your terminal to extreme temperatures.
Use your terminal with original accessories. Attempts to integrate unapproved
accessories to the terminal will void your warranty.
Due to electrostatic discharge, and depending on the environment, synthetic carpet
should be avoided in areas where the terminal has been installed.
Areas containing combustibles
It is strongly recommended that you do not install your terminal in the vicinity of gas
stations, petroleum processing facilities or any other facility containing flammable or
combustible gasses or materials.
Specific precautions for terminals equipped with a contactless
smartcard reader
It is recommended to install terminals equipped with a contactless smartcard reader
at a certain distance (> 30cm) from metallic elements such as iron fixations or lift gates
or radio product (such as contactless smartcard reader). Performances in terms of
contactless badge reading distance will decrease when metallic elements are closer.
Ethernet connection
It is recommended to use a category 5 shielding cable (120 Ohms). It is also strongly
recommended to insert a repeater unit every 90m.
Extreme care must be taken while connecting Ethernet wire to the terminal block
board since low quality connection may strongly impact Ethernet signal sensibility.
It is recommended to connect Rx+ and Rx- with the same twisted-pair wire (and to do
the same with Tx+/Tx- and the other twisted-pair wire).
Date / Time synchronization
The terminal clock has a +/-10 ppm typical time deviation at +25°C (roughly /-
6 sec per 48 hours). At lower and higher temperature (but within normal operating
