Measurements; Warnings; Advanced Screen - Gemini 720is Product Manual

Gemini Software Operation
The pointer position is expressed as a range / bearing pair, and as a Cartesian co-ordinate
(X, Y).

5.1.18. Measurements

When the mouse pointer is within the cone on the Gemini data display measurements can
be taken from the display. A single click on the cone will show the position of the click.
Clicking at one point on the cone and holding the left mouse button down whilst moving the
mouse will give a measurement between the two points.
When any measurement has been taken, clicking outside the cone will turn the measurement
off.

5.1.19. Warnings

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, but will heat up more rapidly than if it was in water, and it
may reach a temperature where it will automatically shut down to protect itself. If this happens,
it will not be possible to communicate with or operate the Gemini until it has cooled to a safe
temperature.

5.2. Advanced Screen

The Advanced screen is accessed by clicking the Advanced tab at the upper left hand
corner of the screen.
