Installing a MicroSD Card

The microSD card slot provides secondary non-volatile storage and is located under the battery pack. Refer to the documentation provided with the card for more information, and follow the manufacturer's recommendations for use.

CAUTION-ESD: Follow proper electrostatic discharge (ESD) precautions to avoid damaging the microSD card. Proper ESD precautions include, but are not limited to, working on an ESD mat and ensuring the operator is properly grounded.

Remove the access cover.
Slide the microSD card holder to the Open position.
Lift the microSD card holder door.
Insert the microSD card into the card holder, ensuring that the card slides into the holding tabs on each side of the door.
Close the microSD card holder door.
Slide the microSD card holder door to the Lock position.

IMPORTANT: The access cover must be replaced and securely seated to ensure proper device sealing.

Installing the SIM Card

CAUTION-ESD: Follow proper electrostatic discharge (ESD) precautions to avoid damaging the SIM card. Proper ESD precautions include, but are not limited to, working on an ESD mat and ensuring the operator is properly grounded.

Remove the access cover.
Slide the SIM card holder to the Unlock position.
Lift the SIM card holder door.
Place the SIM card into the card holder with contacts facing down.
Close the SIM card holder door.
Slide the SIM card holder door to the Lock position.

IMPORTANT: The access cover must be replaced and securely seated to ensure proper device sealing.

Installing or Removing a Battery

This section describes how to install a battery into the device and how to remove it.

NOTE: Do not put any labels, asset tags, engravings, stickers, or other objects in the battery well. Doing so may compromise the intended performance of the device or accessories. Performance levels such as sealing (Ingress Protection (IP)), impact performance (drop and tumble), functionality, or temperature resistance could be affected.

To install a battery:
1. Insert the battery, bottom first, into the battery compartment in the back of the device.
2. Press the battery down until it snaps into place.
To remove a battery:
1. Press the two release tabs inward.
2. Lift the battery from the device.

Using the Rechargeable Li-Ion Battery with BLE Beacon

This device utilizes a rechargeable Li-Ion battery to facilitate BLE Beacon. When BLE Beacon is enabled, the battery transmits a BLE signal for up to 7 days while the device is powered off due to battery depletion.

NOTE: The device transmits a Bluetooth beacon only when the device is powered off or in Airplane Mode.

For additional information on configuring the Secondary BLE settings, see techdocs.zebra.com/emdk-for-android/11-0/mx/beaconmgr/.

Charging the Device

To achieve optimal charging results, use only Zebra charging accessories and batteries. Charge batteries at room temperature with the device in sleep mode.

A standard battery charges from fully depleted to 90% in approximately 2 hours and from fully depleted to 100% in approximately 3 hours. In many cases, a 90% charge provides enough charge for daily use. Depending on the usage profile, a full 100% charge may last for approximately 14 hours of use.

IMPORTANT: Follow the guidelines for battery safety described in the Battery Best Practices file available at zebra.com/batteries.

The device or accessory always performs battery charging in a safe and intelligent manner. The device or accessory indicates when charging is disabled due to abnormal temperatures via its LED, and a notification appears on the device display.

Temperature	Battery Charging Behavior
20 to 45°C (68°F to 113°F)	Optimal charging range.
0 to 20°C (32°F to 68°F) 45 to 50°C (113°F to 122°F)	Charging slows to optimize the JEITA requirements of the cell.
Below 0°C (32°F) Above 50°C (122°F)	Charging stops.
Above 58°C (136°F)	The device shuts down.

To charge the device using a cradle:

Connect the charging accessory to the appropriate power source.
Insert the device into a slot to begin charging. Ensure that the device is properly seated.

The device turns on and begins charging. The Charging/Notification LED blinks amber while the device is charging and then turns solid green when the device is fully charged.

Charging the Spare Battery

This section provides information on charging a spare battery. To achieve optimal charging results, use only Zebra charging accessories and batteries.

Insert a spare battery into the spare battery slot.
Ensure the battery is seated properly.

The Spare Battery Charging LED blinks indicating charging. The battery charges from fully depleted to 90% in approximately 2.5 hours and from fully depleted to 100% in approximately 3.5 hours. In many cases, the 90% charge provides plenty of charge for daily use. Depending on the usage profile, a full 100% charge may last for approximately 14 hours of use.

Charging Indicators

The charging/notification LED on the device indicates the charging status.

State	LED Color	Indications
Off		The device is not charging. - The device is not inserted correctly in the cradle or connected to a power source. - The charger/cradle is not powered.
Slow Blinking Amber (1 blink every 4 seconds)		The device is charging.
Slow Blinking Red (1 blink every 4 seconds)		The device is charging, but the battery is at the end of its useful life.
Solid Green		Charging is complete.
Solid Red		Charging is complete, but the battery is at the end of its useful life.
Fast Blinking Amber (2 blinks/second)		Charging error, such as: - Temperature is too low or too high. - Charging has gone on too long without completion (typically twelve hours).
Fast Blinking Red (2 blinks/second)		Charging error, and the battery is at the end of its useful life. For example: - The temperature is too low or too high. - Charging has gone on too long without completion (typically 12 hours).
