Using a M3 Allen key, unscrew the top and
bottom retention screws from the cover.
Once both screws have been removed,
gently pull the cover away from the main
body of the sonar.
The area surrounding the transmitter and
receiver can now be visually inspected
for any salt deposits and cleaned as
appropriate.
Note
To reattach the cover, simply reverse these steps.
Caution
Do not deploy the Gemini without the cover being attached to the unit.
It is recommended that Gemini units be returned to Tritech as part of a regular maintenance
schedule. An annual return is highly recommended, but this can be lengthened, or shortened,
by various factors:
• Frequency of use
• The operating environment (i.e. salinity, temperature)
• The presence of any galvanic action from dissimilar metals, or case voltages
