Maintenance - QYSEA FIFISH V6 Quick Start Manual

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 Motors and Battery
Maintenance Guide)
2. Keep the ROV tether plug dry and clean. 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, page 5-9) 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.
