Limitation | Recommendation |
|---|---|
Absence of a backup battery to maintain system time. | The device is powered by a single removable battery. When you power off the device without a battery power source, for example, when the battery is fully discharged or removed, the system time configuration is reset. Zebra recommends that you connect the device to a Wi-Fi network with DHCP and utilize time synchronization with NTP to automatically restore and maintain the correct time. |
Removing the device battery while the device is powered on can cause issues. | Zebra does not recommend ejecting the battery when the device is operational. The device does not have an alternative power source except the main battery. Removing the battery can result in potential issues, such as file system corruption. To remove the battery Zebra recommends that you first power off the device (Press Power Button , then Power Off ), and then remove the battery. |
Two-way audio in Handset mode is not supported. | The device has a single microphone and speaker. If the internal speaker and microphone are used together, for example, for a two-way audio function, there can be user-perceivable echo and/or degradation in overall voice quality. Zebra recommends an external USB or Bluetooth headset for use cases that require simultaneous use of speaker and microphone functions. |
The gun trigger for barcode scanning is available only when the application is connected to the RFID reader. | Gun trigger activation of the barcode scanner requires an application to maintain RFID functionality. In an existing barcode scanning application, for example, the Zebra Enterprise Mobility Development Kit, which currently utilizes the left trigger button for activating barcode scanning and requires the use of the gun trigger as well for the barcode scanner, the application needs modification to use RFID APIs to open the RFID device and keep the device open for the duration of scanning application usage. Refer to "Hello RFID Application" tutorial in Android RFID APIs on how the RFIDReader class and its Connect() method are used to connect to RFID. |
UHF RFID and NFC functions are exclusive to each other. | When UHF RFID is enabled, NFC is unavailable, and vice versa. This limitation is by design to protect the device's overall power consumption and cannot be overridden. |
NFC gets enabled in Airplane mode after a device reboot. | If airplane mode is activated, radios, including NFC, are turned off. However, if the device is rebooted, NFC is re-enabled. Zebra recommends to manually disable NFC using Android Quick Settings from the Notification Quick Access Panel. |
Operating at the highest RFID transmit power at low battery level and low temperature. | Zebra recommends that you not operate RFID at 32 dBm with low battery levels (20% and below), and at low operating temperatures (approximately -10° C/50° F). The device may power off resulting in data loss. When operating at very low temperatures, ensure the battery has a charge of at least 50%. Alternatively, consider operating at a lower transmit power level of 27 dBm or lower if the battery level is low (below 20%). |
The scanning session times out in 2 seconds if the RFID is connected. | When using RFID, the barcode scanning session times out after two seconds if the barcode is not in the field of view. This limitation is by design to prevent high power consumption. If the scanning session needs to be prolonged beyond two seconds, close the RFID application. |
Continuous scanning mode and presentation mode are not supported. | The scanner in the device does not support continuous scanning mode and presentation mode in DataWedge. This limitation is by design to limit power consumption. |
The Fastest Read mode in 123RFID is not recommended for continuous use. | Prolonged use of the device in this mode can quickly drain the battery and may cause the unit to overheat. Zebra recommends, that you enable Balanced Mode with Dynamic Power Optimization . |
