Installing a microSD Card

The microSD card slot provides secondary non-volatile storage. The slot 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.

1. Lift the access door.
2. Slide the microSD card holder to the Open position.
3. Lift the microSD card holder door.
4. Insert the microSD card into the card holder ensuring that the card slides into the holding tabs on each side of the door.
5. Close the microSD card holder door.
6. Slide the microSD card holder door to the Lock position. NOTE: Access door must be replaced and securely seated to ensure proper device sealing.
7. Re-install the access door.

Installing the Battery

This section describes how to install the battery into the device.

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 affected. 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.
2. Press the battery down until it snaps into place.

Using the Rechargeable Li-Ion Battery with BLE Beacon

This device utilizes a rechargeable Li-Ion battery to facilitate BLE Beacon. Once 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 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/mx/beaconmgr.

Charging the Spare Battery

This section provides information on charging a spare battery.

1. Insert a spare battery into the spare battery slot.
2. Ensure the battery is seated properly. The Spare Battery Charging LED blinks indicating charging. See Charging Indications on page 10 for charging indicators.

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 lasts for approximately 14 hours of use. To achieve the best charging results use only Zebra charging accessories and batteries.

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

Charging the Device
This section provides information for charging the device.
NOTE: Ensure that you follow the guidelines for battery safety described in the TC73/TC78 Product Reference Guide.

1. To charge the main battery, connect the charging accessory to the appropriate power source.
2. Insert the device into a cradle or attach to a cable. The device turns on and begins charging. The Charging/Notification LED blinks amber while charging, then turns solid green when fully charged.

The standard battery charges from fully depleted to 90% in approximately two hours and from fully depleted to 100% in approximately three hours. In many cases the 90% charge provides plenty of charge for daily use. Depending on usage profile, a full 100% charge lasts for approximately 14 hours of use. To achieve the best charging results use only Zebra charging accessories and batteries. Charge batteries at room temperature with the device in sleep mode.

Charging Indications

Scanning

To read a barcode, a scan-enabled application is required. The device contains the DataWedge application that allows the user to enable the imager, decode the barcode data and display the barcode content.

NOTE : The SE55 displays the green dash-dot-dash aimer. The SE4720 imager displays a red dot aimer.

1. Ensure that an application 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.

3. Press and hold the scan button.
   To assist in aiming, the red LED aiming pattern and red aiming dot turn on for the SE4720 and the green LED aiming pattern and green dash-dot-dash turn on for the SE55.
   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 in the aiming pattern. The aiming dot is used for increased visibility in bright lighting conditions. Figure 3 Aiming Pattern Figure 4 Pick List Mode with Multiple Barcodes in Aiming Pattern

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.
