WARNING: Although selected for their ruggedness, the solid–state accelerometers
and rate sensors used in the IMU are susceptible to excessive shock and vibration.
Refer to the environmental specifications for details. Treat the IMU with care when
you handle it—store it in the transit case until you are ready to install it. Never drop
the IMU or subject it to shocks. A 'Shockwatch' label attached to the IMU casing will
show a red central vial if the unit is subjected to severe shock. If this occurs, return the
unit to CodaOctopus Limited for test and repair. The solid–state inertial measurement
components are not field repairable.
WARNING: A common point of failure is damage to the two antenna cables. Any
exterior or interior damage to the cables can deteriorate the GNSS signal strength to a
point where the system turns unreliable. Special care should therefore be considered
when installing and fixing the cables to the vessel structure. Cables should not be
subject to a short bend radius or stepped on as it can break the internal insulation
layer.
