Warnings
Reusable electrodes present a potential risk of cross-infection especially when used on
abraded skin, unless they are restricted to a single subject.
To prevent contamination: store electrodes in a separate bag within the packaging.
Do not attempt to service any part of the product while it is in use or connected to a
subject.
There are no user serviceable parts within the product. Repairs can only be performed by
the manufacturer.
When connecting the system in an IT-network:
Simultaneous connection of other equipment to the same optical fiber may result in
previously unidentified risks to subjects, operators or third parties. Such risks must be
identified, analyzed, evaluated and controlled. Subsequent changes to the optical fiber can
introduce new risks that require additional analysis. Changes to the IT-network include:
changes to its configuration, connecting additional items, disconnecting items, updates and
upgrades of connected equipment.
Clean the product only according to the cleaning instructions in this manual. Before
cleaning, make sure the device is switched off. Never use any aggressive chemicals to
clean the product.

Precautionary measures
Make sure that the wall socket is well earthed, to reduce 50 or 60 Hz
disturbances.
Do not use an operating cellular phone within 50 cm of the device to avoid excessive noise on the
signals.
Sharp bends or winding the cables in a loop smaller than 5 cm diameter may damage the cables.
Do not bend the glass fiber too sharply, as it may break.
