The PD20 is not powering up when running a transaction. | If the PD20 is not used for an extended period, it must be charged from a power source for at least 30 minutes before a transaction. | Charge the PD20 using a USB-C cable connected to a power supply (for example, a USB cable connected to a wall plug adapter). After 30 minutes, re-attach the PD20 to the device. |
The PD20 is not communicating with the device. LED 1 is on, and LED 4 is flashing. | The PD20 has been tampered with. | Tampered devices can no longer be used and should be discarded or recycled. For recycling and disposal advice, refer to zebra.com/weee. |
The PD20 battery level is inconsistent while charging versus when not charging. | While the device is charging, the PD20 battery level may not be accurate. | After removing the PD20 from the charger, wait 30 seconds before checking the battery level. |
