Maintenance
1. Soak ROV at least 1 hour after dive, then let the motors run in fresh water at least
10 minutes and rinse the ROV with fresh water. Air dry and avoid direct sunlight (for
more information, please check the
Maintenance Guide
)
2. Keep the every connector (port and plug) dry and clean at all time. Put on the
protective cap all the time. The salt and moisture may cause corrosion on the
connector. Clean the plug with running fresh water and dry with cotton pad or tissue
paper.
3. Check the propellers after every dive. Make sure NO entanglement, i.e. seaweed or
fishing lines. Turn on the ROV (See the
Preparation & Connection
Section ) and
check the thruster and test movement and rotation.
4. Clean sand regularly. Soak the ROV inside the clean fresh water at least 1 hour.
Shake ROV tail down or head down position, let sand washed out through the
venting holes. Wash until the clean water drips out.
5. Check the tether on regular basis, replace the tether if break or damage appears.
6. Store ROV and RC in dry and cool environment (Temperature range: 5°C to 25°C
or 41°F to 77°F).
7. For long-term storage, keep 50% to 60% of battery level. Charge and discharge
every 90 days to keep the activation of Lithium battery.
