Power Considerations
If the battery is not continuously recharged either by a solar recharge system or some other
recharge system, it may require replacement. All data is preserved for about half an hour after that
data can’t be recovered.
Note: If the 12V power is disconnected for more than 30 minutes, recorded data will be lost.
Note: If the 12V power falls below 11V, the Starflow will stop recording, it enters “Sleep
Mode.”

Drying Tube and Desiccant
The Starflow cable contains a tube to vent the water depth pressure sensor to atmospheric
pressure. It is very important to ensure that NO MOISTURE enters the vent tube, as this will cause
erratic depth measurements.
The Starflow connector vents the cable through a Drying Tube (Model 6603DT) containing “Silica
Gel” desiccant.
Replace or regenerate the desiccant when it changes colour from blue to pink.
