7 Troubleshooting
This section is intended to provide a simple means of determining if a problem exists in
the KVH DSP-3000 gyro and assumes that the unit has passed the bench testing described
in previous sections.
The DSP-3000 is supplied as a sealed unit. Breaking the QA
seals voids the warranty and may violate the contract under
which the unit was supplied.
The warranty does not apply if the unit has been damaged by
misuse or as the result of service or modification other than by
KVH Industries.
