Prerequisites: Before You Start
- You have physical access to the device (required for SIM and antenna checks).
- You have Operator access in Nayax Core (required for remote restart and communication mode changes).
- You know the Device serial number or operator name to locate the device in Nayax Core.
- For the Ethernet option, you have an Ethernet adapter (available from Nayax) and a LAN cable.
Work through steps in order. Each step includes a Yes/No gate — stop as soon as the error clears. If you complete all steps and the error persists, contact Nayax Support with your device serial number and the steps already attempted.
⚠️ Before you start — check for a known outage
If multiple devices at the same location or across your account are showing M02/M06 simultaneously, the cause may be a network or carrier outage - not an issue with the individual device. Device-side troubleshooting steps will not resolve an outage.
Check the Nayax status page first: status.nayax.com. If an active incident is listed for your region, contact Nayax Support directly and reference the incident - do not attempt device-side steps until the outage is resolved.
