Kindle users will lose Internet connectivity on their devices if they don't install a crucial update before March 22, Amazon has warned.
This would mean services such as downloading books, accessing the Kindle Store and other Internet-dependent tasks would not work.
The Amazon update applies to Kindles sold in 2012 and before.
If the update is not done before March 22, users will receive the following message on their devices: "Your Kindle is unable to connect at this time. Please make sure you are within wireless range and try again. If the problem persists, please restart your Kindle from the menu in settings and try again."
If users miss the deadline, they will have to manually install the update by downloading it on a computer or laptop, then plugging in the Kindle via a USB connection and transferring the software to the device.
Amazon has released a table outlining what generation devices require updating.
The U.S. e-commerce giant has also outlined instructions on how to update the Kindle here.
