5.1.19. Warnings

Out of water
If the Gemini detects that it is not immersed in water, the warning "Out of water" will be
displayed in the centre of the scan image:
The sonar will continue to operate at full power during a 20 minute countdown period. During
the countdown period, toggling the Online button will reset the timer back to the start or
immersing the sonar back into water will clear the warning.
At the end of this period the sonar will enter a power saving mode to reduce the heat build
up within the unit. The software will still display information about the sonar during this power
saving mode, but the sonar will not re-enable it's ability to transmit until the Online button
has been toggled off then on.
Over temperature
If the temperature sensors within the sonar detect that the internal temperature is too high
an "Over temperature" warning will be displayed.
The sonar will enter a power saving mode and only basic communication with the unit will
be possible. Cooling the unit and then toggling the Online button will clear the warning and
resume the full capabilities of the sonar.
