Installing the Battery
NOTE : User modification of the device, particularly in the battery well, such as labels, asset tags, engravings, stickers, etc., may compromise the intended performance of the device or accessories. Performance levels such as sealing (Ingress Protection (IP)), impact performance (drop and tumble), functionality, temperature resistance, etc. could be effected. DO NOT put any labels, asset tags, engravings, stickers, etc. in the battery well.
1. Insert the battery, bottom first, into the battery compartment in the back
of the device.
Figure 9 Insert Bottom of Battery into Battery Compartment
2. Press the battery down into the battery compartment until the battery release latches snap into place.
Charging the Device
CAUTION: Ensure that you follow the guidelines for battery safety described in
the device Product Reference Guide.
Use one of the following accessories to charge the device and/or spare
battery.
Table 3 Accessories
Main Battery Charging
To charge a device:
1. Insert the device into a slot to begin charging.
2. Ensure the device is seated properly.
The device’s Charging/Notification LED indicates the status of the battery charging in the device. The 3,220 mAh (typical) standard battery charges from fully depleted to 90% in approximately 2.5 hours and from fully depleted to 100% in approximately three hours. The 5,260 mAh (typical) extended battery charges from fully depleted to 90% in approximately four hours and from fully depleted to 100% in approximately five hours.
NOTE : In many cases the 90% charge provides plenty of charge for daily use.
To achieve the best fast charging results use only Zebra charging accessories and batteries. Charge batteries at room temperature with the device in sleep mode.
Table 4 Charging/Notification LED Charging Indicators
Spare Battery Charging
To charge a spare battery:
1. Insert the battery into a battery charging well.
2. Gently press down on the battery to ensure proper contact.
The Spare Battery Charging LED on the cup indicates the status of the spare battery charging. The 3,220 mAh (typical) standard battery charges from fully depleted to 90% in approximately 2.5 hours and from fully depleted to 100% in approximately three hours. The 5,260 mAh (typical) extended battery charges from fully depleted to 90% in approximately four hours and from fully depleted to 100% in approximately five hours.
NOTE : In many cases the 90% charge provides plenty of charge for daily use.
To achieve the best fast charging results use only Zebra charging accessories and batteries.

Charging Temperature
Charge batteries in temperatures from 0°C to 40°C (32°F to 104°F). The device or cradle always performs battery charging in a safe and intelligent manner. At higher temperatures (for example: approximately +37°C (+98°F)) the device or cradle may for small periods of time alternately enable and disable battery charging to keep the battery at acceptable temperatures. The device and cradle indicates when charging is disabled due to abnormal temperatures via its LED.

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 on the top of the device at a barcode.
Figure 17 Imager Scanning
3. Press and hold the scan button.
The red laser aiming pattern turns on to assist in aiming.
NOTE : When the device is in Picklist mode, the imager does not decode the barcode until the crosshair or aiming dot touches the barcode.
4. Ensure the barcode is within the area formed by the crosshairs in the aiming pattern. The aiming dot increases visibility in bright lighting conditions.
Figure 18 Aiming Pattern
Figure 19 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.
Ergonomic Considerations
CAUTION: Avoid extreme wrist angles.
