What to do if there are internal components issue with OTT Hydrolab DS5X Transmitter?
- E
  Eric WilsonSep 9, 2025
  If you suspect an issue with the internal components, make sure all internal connections are securely seated. Check for any water inside the unit; if damp, dry it thoroughly with a lint-free cloth or let it air dry in a dry room overnight. Identify and repair the source of the leak. If these steps don't solve the problem, try substituting other instruments, cables, and terminals to find the failing component.
