The Nayax Onyx contactless readers are designed to provide a simple way to credit our arcade machines or payout arcade tokens.
In normal operation these readers do not need any servicing, hwowever, external factors can affect their daily operation.

Nayax displayed Errors
The Onyx reader manages a number of self checks and should it run into an issue with usually display an error message.
The units screen will display a yellow warning explanation mark inside a triangle and below this should be an error message.
Common Error Messages
The display may say 'Cashless Only' or 'Out of Order'.
- V00 - Indicates an internal communication issue within the change machine
- V01 - Indicates that the change machine has disabled the Nayax Onyx Reader
- V02 - Indicates that the Nayax Onyx Reader has been set in an 'Disable' state
- M00 - Indicates that the Nayax Modem has become stuck on initialization
- M01 - Indicates that the Nayax Onyx has no SIM card or cannot communicate with it
- M02 - Indicates that the Nayax Modem cannot communicate with a Mobile Network, or the network connection has timed out
Nayax Onyx 'V' Codes
In the case of a 'V' error it is likely the change machine parts are not correctly fixed.
The most common issues is simply that the token hopper is empty and simply needs filling up again.
Another common issue is that the token hopper is misaligned inside the change machine.
Check the Token Hopper
It is important to visually check the hopper for possible damage before trying to refit it.
A very common issue is where one, or more, of the connection pins on the rear of the hopper have become bent. If this is the case most likely it is an bent pin on the bottom row (see image below where the left hand bottom pin is bent).
COMMENT: When trying to open the change machines door you might notice that the bottom lock is harder to turn than the top lock. This is a key indicator that the token hopper is misaligned or has bent pins.
If this is the case then push on the door, as if you where closing it, and then try to turn the lock. In many cases it will turn much easier.
Nayax Onyx 'M' Codes
The most common issue is an M02 error code. When displayed it means that the Nayax has experienced a problem while trying to connect to a mobile network signal and/or in some cases has failed to get a local network signal (LAN connection).
The Nayax reader should still respond to user requests at this point. Push the menu button on the front of the Nayax unit, as indicated by 3 lines. You should be presented with a screen with a few options. Look for the top left button here, marked .... and push it.
The screen should change to show information regarding the mobile service it is receiving. Like on modern smartphones there is a signal strength indicator and below it an 'RSSI' reading.
Understanding the RSSI Reading
Read this guidance for how to check the RSSI reading Opening the RSSI Menu
The RSSI is reported as a number and scales between 0 and 99. Strange as it might seem, the lower the number the better the mobile service the Nayax Onyx is receiving. These readers can in fact connect to any mobile network service and will pick the strongest signal it can find at start-up.
For everyday reliable operation is it best to have an RSSI that is under 20. In fact even to about 34 that service should work, but might be slower to respond.
Anything above this figure will normally mean there is not really a good enough or reliable enough signal for the Nayax Onyx to operate fully. This is likely to lead to periods of no service, as the Mobile Signal fluctuates.
Fault Resolutions for Nayax Onyx 'M' Codes
In most cases this is reliant upon the Mobile Network Signal returning to a usable level and hopefully the Nayax Onyx will start to operate normally again.
Effectively there is little else an operator can do. Relocating the machine, or moving the aerial location, to try and help secure a better signal.
However, the best solution for problematic signal service is to connect the Nayax Reader to a Local Area Network Service (LAN).
This is a job for our service team working in partnership with the venue to secure such a LAN service and re-fit the Nayax Onyx with new cables.
