The Rechargeable Li-Ion Battery with BLE Beacon

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

NOTE: The device transmits a Bluetooth beacon only when it is powered off or in airplane mode. For additional information on configuring the Secondary BLE settings, see techdocs.zebra.com/emdk-for-android/13-0/mx/beaconmgr/.

The Rechargeable Li-Ion Wireless Battery

Use a rechargeable Li-Ion battery to facilitate wireless charging.

NOTE: The rechargeable Li-Ion wireless battery must be used along with the device in the Zebra Wireless Charge Vehicle Cradle or Qi-certified wireless chargers.

The BLE Beacon

The rechargeable Li-Ion battery facilitates Bluetooth Low Energy (BLE) Beacon. When enabled, the battery transmits a BLE signal for up to seven days while the device is powered off due to battery depletion.

NOTE: The device transmits a Bluetooth beacon only when it is powered off or in airplane mode. For additional information on configuring the Secondary BLE settings, see techdocs.zebra.com/emdk-for-android/13-0/mx/beaconmgr/.

Charging the Device

Use only Zebra charging accessories and batteries to achieve optimal charging results. Charge batteries at room temperature with the device in Sleep mode.

The device goes into Sleep mode when you press Power or after a period of inactivity.

A battery charges from fully depleted to 90% in approximately 2 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.

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

To charge the main battery:

1. Connect the charging accessory to the appropriate power source and connect it to the device. [Diagram showing connecting the charging accessory]
2. Insert the device into a cradle or attach to a power cable (minimum 9 VDC / 2 A). [Diagram showing device in cradle/connected to power cable]

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

Charging Indicators

The charging/notification LED indicates the charging status.

Table 4: Charging/Notification LED Charging Indicators

Charging the Spare Battery

This section provides information on charging a spare battery. Use only Zebra charging accessories and batteries to achieve optimal charging results.

1. Insert a spare battery into the spare battery slot. [Diagram showing inserting a spare battery]
2. 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. 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.

Accessories for Charging

Use one of the following accessories to charge the device and/or spare battery.

Charging and Communication

1-Slot Charge Only Cradle

This USB cradle provides power, spare battery charging, and host communications.

CAUTION: Ensure that you follow the guidelines for battery safety described in the Product Reference Guide.

1-Slot USB/Ethernet Charge Cradle

The 1-Slot USB/Ethernet Charging Cradle charges one device and one spare battery while also connecting a device to the Ethernet network.

CAUTION: Ensure that you follow the guidelines for battery safety described in the Product Reference Guide.

5-Slot Charge Only Cradle

CAUTION: Ensure that you follow the guidelines for battery safety described in the Product Reference Guide.

• Provides 5.0 VDC power for operating the device.
• Simultaneously charges up to five devices or up to four devices and four batteries using the 4-slot battery charger adapter.
• Contains a cradle base and cups that can be configured for various charging requirements.

5-Slot Ethernet Cradle

CAUTION: Ensure that you follow the guidelines for battery safety described in the Product Reference Guide.

• Provides 5.0 VDC power for operating the device.
• Connects up to five devices to an Ethernet network.
• Simultaneously charges up to five devices or up to four devices and four batteries using the 4-slot battery charger adapter.

4-Slot Device Charge Only Cradle and Spare Battery Charger

The 4-Slot Device Charge Only Cradle and Spare Battery Charger charges up to four devices and four spare batteries.

CAUTION: Ensure that you follow the guidelines for battery safety described in the Product Reference Guide.

• Provides 5.0 VDC power for operating the device.
• Simultaneously charges up to four devices and four spare batteries.

Charge/USB-C Cable

The USB-C Cable snaps onto the bottom of the device and removes easily when not in use.

NOTE: When attached to the device, it provides charging and allows the device to transfer data to a host computer.

True Battery Hot Swap

Replacing the main battery via hot swap allows the device to maintain Wi-Fi/WAN connectivity and memory persistence while replacing the depleted battery with a fully charged battery.

NOTE:

• The volume level is set at a maximum of 50% while performing a battery hot swap and is set to the original volume when the battery is replaced.
• Audio calls made while using a Bluetooth or wired headset are maintained during the battery hot swap.
• Push-to-talk applications maintain a network connection during the true battery hot swap, so long as the app remains open.

When the battery is removed, the backup supercapacitor immediately takes over to maintain the system, including Wi-Fi/WAN connectivity (only voice, data, and current state of applications), for 30 seconds. During this time, the user can still interact with the device. The display turns off, and the touchscreen is disabled to conserve power.

To ensure your device can remain functional for the full expected duration during a hot swap, refer to this table:

After 30 seconds without a battery, the device enters an emergency (critical) suspension mode, which maintains the memory cache for an additional 30 seconds. This allows the device to resume operation, rather than rebooting, so long as the battery is replaced within this 60-second window. If the battery is not reinstalled in time, memory persistence may be lost, causing the device to reboot when a charged battery is inserted.

Incoming calls received before replacing the battery are suspended and will resume when a fresh battery has been inserted. The performance of these calls depends on temperature and signal strength.

Performing a True Battery Hot Swap

This section describes how to perform a battery hot swap for the device.

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.

CAUTION-PRODUCT DAMAGE: Do not add or remove a microSD, SAM, or SIM card during battery replacement.

1. Ensure the device is ready for a battery swap by checking the notification bar. NOTE: If the device is not ready, a notification will display Backup power not ready for battery swap.
2. Remove any accessories blocking access to the battery.
3. Press the battery latches down and inward towards the center of the device. [Diagram showing pressing battery latches]

CAUTION: Do not insert fingers under the latches while pulling on the battery, as this can damage the latches.

1. Pull the battery out of the device. [Diagram showing pulling the battery out]

NOTE: You will have 30 seconds to insert the new battery, or the device will enter emergency (critical) suspension mode. After 60 total seconds, the device will be rebooted once the replacement battery is inserted.

1. Insert the bottom edge of the replacement battery into the battery compartment at the back of the device.
2. Press the battery in until it clicks into place.

Ergonomic Considerations

Avoid extreme wrist angles when using the device. [Diagram illustrating proper and improper wrist angles]
