# Enabling Aztec Code on Datalogic Gryphon Scanners

Aztec Code is **disabled by default** on the Datalogic Gryphon 2D scanners (GD44XX / GBT4400 / GM440X, including the 4400-BK). If the scanner reads normal QR and 1D barcodes but ignores Aztec codes, enable the symbology using the steps below.

## Enable Aztec Code

Scan these barcodes in order:

1. **Enter/Exit Programming Mode**
2. **Aztec Code = Enable**
3. **Enter/Exit Programming Mode** again to save and exit

If Aztec codes shown on a phone or screen still will not read, also enable **2D Normal/Inverse Symbol Control** (some screen codes are reverse-video).
