“POS tampered, request authority” - A tampered terminal is a terminal that has been damaged in some way (i.e., being dropped, power surge).
When a terminal is considered tampered with, it is no longer usable and will need to be replaced.
If your terminal shows such error - please immediately contact our support email [email protected] and we will either assist with terminal replacement, or will direct you who you should contact.
“Terminal is locked” - Terminal has been locked in Terminal Management System, to unlock it, you need to contact the company, that provided you the terminal, and they will be able to unlock it.
“Lower Voltage” (during printing) - The battery does not have enough power for the printer to operate. To fix this :
Charge the terminal for at least 15–20 minutes
Ensure the battery is seated correctly
Avoid printing receipts when battery is below 20%
If this happens frequently → the battery may need replacement
You can still take payments, but printing may fail until the battery is charged.
