Locator-U1

  • No green light
    Power is off; the Locator-U1 is not ready for diving.

  • Flashing green light (once per second)
    The Locator-U1 is searching for GPS lock and is not ready to dive.

  • Fixed green light
    The Locator-U1 has GPS lock and is ready to dive.

  • Flashing green light (slow)
    The Locator-U1 previously had GPS lock but lost it. It is still ready to dive.

  • Fast flashing green light (multiple times per second)
    Error indication. The Locator-U1 is not ready to dive. This often happens if the device has exceeded its dive time and the pressure sensor requires drying, or if the battery power is very low. Charging the Locator helps to dry the sensor more quickly.

Note

The LED does not say anything about the battery status of the Locator-U1. The locator always needs to be charged for at least 7 hours with a proper 5V/2A charger befor use.
