Figure 29: Power-Off Timing

When saving scan engine configurations, settings are stored in the scan engine:
•
when the Z2 command is sent.
•
after 1D or 2D menu barcodes are processed.
Writing these settings to flash memory can take up to 10 seconds. Make sure the power is not
turned off during this period, or the settings may be corrupted.
Note: When the Z2 command is sent, if "ACK/NAK for serial command" is enabled, the scan
engine sends an ACK after saving the configuration data.
