### Using Sound Events

Sound Events provide audible feedback in addition to the visual user interface. This allows you to perform measuring actions without needed to look at the PC screen. To access the Sound Events tab of the SetUp Options dialog box, select the Edit | Preferences | Setup menu item.

Calibration Sound Events

When calibrating a laser device there are Sound Event options that are particularly useful. They are:

Laser Manual Calibration Bottom: The associated sound is played when calibration measurements for a given field should be taken in the upper region (location) of the sphere.

Laser Manual Calibration Field Counter: The associated sound is played to indicate in which field calibration measurements should be taken.

- 1 Beep - Measurement should be taken in the Far field.

- 2 Beeps - Measurement should be taken in the Left field.

- 3 Beeps - Measurement should be taken in the Right field.

Laser Manual Calibration Top: The associated sound is played when calibration measurements for a given field should be taken in the lower region (location) of the sphere.

Laser Probe Initialization End: The associated sound is played when at the end of the laser sensor initialization.

Laser Probe Initialization Start: The associated sound is played when at the beginning of the laser sensor initialization.

Laser Scan: The associated sound is played for each new step of the sensor calibration.

Sound Events for Laser Measurement

When measuring with a laser device audible feedback is provided from the Romer speaker based on the calculated Z distance. This pitch will vary according to the distance from the surface in relation to the optimal target distance.

- Low pitched continuous sound - Indicates that you are closer than the middle 50% of the laser range.

- High pitched continuous sound - Indicates that you are farther than the middle 50% of the laser range.

- Series of beeps - Indicates that you are in the middle 50% (25% below to 25% above) of the optimal target. This the desired range for optimal scanning.

Note: This functionality is probably best used on larger, flatter surfaces. When using a V5 sensor, you may combine the sound events with the V5 projector option to ensure scanning at the optimal focal length. You can compare the V5 projector in relation to the audible cues to learn what the beeps mean.
