# Trigger Types

The DataMan 8600 trigger mode determines when the reader attempts to read a code. Use the DataMan Setup Tool or the appropriate reader configuration codes to change trigger types.

Supported trigger types:

- Manual (default): Pressing the trigger button on the reader starts image acquisition. The reader continues to acquire images until thare is a detectable and decoded image or until the release of the trigger button.
- Presentation: The LED aimer is always on. When motion is detected in front of the reader, the reader turns on and scans for a symbol. The reader relies on an internal timing mechanism to acquire images.

Note: While in Presentation mode, pulling the trigger switches the reader to Manual mode until the device is re-docked on the base station. Setup Tool continues to display Presentation mode while in this state.

To bring the reader back to Presentation mode, use one of the following options:

- Dock the device into the base station
- Switch to Manual trigger mode in Setup Tool, then switch back to Presentation mode
- Scan the Enter Presentation Reader Configuration Code
