Charging Temperature
When charging the battery pack, do so in an ambient temperature range of 0 °C to 40 °C. The device or
accessory always performs battery charging in a safe and intelligent manner. At higher temperatures
(e.g. approximately +37°C) the device or accessory may for brief periods of time alternately enable and
disable battery charging to keep the battery at acceptable temperatures. The device or accessory
indicates when charging is disabled due to abnormal temperatures via its LED and a notification
appears on the display.

Scanning
Scanning with Internal Imager
To read a barcode, a scan-enabled app is required. The device contains the DataWedge app that allows the
user to enable the imager, decode the barcode data, and display the barcode content.
To scan with the internal imager:
1. Ensure that an app is open on the device and a text field is in focus (text cursor in text field).
2. Point the exit window at the desired barcode.
3. Press and hold the scan button.
The white laser aiming pattern turns on to assist in aiming.
MC20 Quick Start Guide
NOTE: When the device is in Picklist mode, the imager does not decode the barcode until the cross-hair or
aiming dot touches the barcode.
4. Ensure the barcode is within the area formed by the cross-hairs in the aiming pattern.

MC20 Quick Start Guide
Figure 2 Pick List Mode with Multiple Barcodes
5. The Data Capture LED lights green and a beep sounds, by default, to indicate the barcode was decoded
successfully.
6. Release the scan button.
NOTE: Imager decoding usually occurs instantaneously. The device repeats the steps required to take a digital
picture (image) of a poor or difficult barcode as long as the scan button remains pressed.
7. The barcode content data displays in the text field.
