Precautions to prevent Electrostatic Discharge (ESD)
Sensitive printed circuit boards and electronic modules must always be transported and
stored in protective antistatic packing bags. The circuit boards and modules must not be
transported or stored close to strong electrostatic, electromagnetic or radioactive fields.
If it is necessary to open and touch the printed circuit board or module inside the
protective bag, the following precautions must be taken:
1 The working area must be covered by an approved conductive service mat that has
a resistance of between 50 kΩ and 2 MΩ, and is connected directly to a reliable
earth point via its earthing cord.
2 You - and all other service personnel involved - must wear a wristband in direct
contact with the skin. The wristband must be electrically connected to the service
mat.
3 Printed circuit boards and electronic modules must be placed on the conductive
service mat during installation and maintenance operations.
4 If, for any reason, it is necessary to move the circuit board from the conductive
service mat, it must be placed in an approved antistatic transportation container (for
example a static shielding bag) before transportation.
5 During installation and servicing, all electrical equipment (for example soldering
irons and test equipment) must be earthed.

Disposal of old products
At the end of the product lifetime, all Kongsberg Maritime products must be disposed of
in an environmentally-friendly way.
All electrical and electronic components must be disposed of separately from the
municipal waste stream via designated collection facilities appointed by the government
or local authorities. The correct disposal and separate collection of your old appliance
will help prevent potential negative consequences for the environment and human health.
This is a precondition for reuse and recycling of used electrical and electronic equipment.
For more detailed information about disposal of your old appliance, please contact your
local authorities or waste disposal service.
All disposal of mechanical, electromechanical, electronic and chemical waste - including
all types of batteries - must take place according to national and international rules and
regulations. Observe the relevant Waste Electrical and Electronic Equipment (WEEE)
regulations.
