Appendix A: Troubleshooting Guide
This appendix provides helpful hints and solutions for troubleshooting the Epoch wireless system. This appendix
addresses issues that may not be consistent across all customers. Consistent, replicable problems will be addressed by
BIOPAC engineers. This appendix will be updated with problems found by customers and solutions determined by
BIOPAC. All solutions have been tested as much as possible by BIOPAC.
Table 1. Epoch wireless system troubleshooting solutions:
The signal status indicator is illuminated even when
there is no sensor in range.
This occurs when there is too much electrical
interference in the environment. BIOPAC recommends
the use of the provided Faraday shield that can be
grounded to the Epoch receiver GND port. It can also be
helpful to use the Epoch system on racks that can be
grounded.
Signal appears to be extremely noisy and/or floating.
This can occur if the ground electrode on the sensor is
not making a low-impedance connection with the
surrounding tissue, or if the electrode becomes encased
in glue during implantation fixation. The solution is to
recheck the electrode placement and possibly the
electrode tip as well.
The signal looks noisy directly after implantation.
The surgical implant procedure often results in acute
trauma that can cause degradation of the signal.
BIOPAC recommends waiting 24 hours post-implantation
before recording signals.
