# Service and Maintenance

The Service and Maintenance (SAM) allows the Verifone support team to enhance Site Solution (ASM) support such as:

* Review the general configuration of the device including network and system configurations
* Review PIN pad diagnostic logs
* Correct some operating system and application issues
* Perform diagnostics remotely on the PIN pad, such as screen calibrations

After the software is installed, the SAM terms and conditions screen displays prompting the owner or store manager to accept or decline the agreement. When the Terms and Conditions are accepted on the PIN pad, the files required for the additional diagnostic capabilities will be installed on the PIN pad.

### Startup After Software Installation

When the PIN pad boots up for the first time, a Terms and Conditions screen displays to Accept or Reject the Service and Maintenance agreement (SAM).

Tap Accept or Reject the Terms and Conditions for the Service and Maintenance Agreement. The startup continues.

{% hint style="info" %}
This prompt displays for five minutes and then times out. The PIN pad will then continue booting up. Also, the prompt displays for five consecutive reboots and then will remain on the screen until it is either Rejected or Accepted.
{% endhint %}

After installation is complete, the Welcome screen displays.

{% endstep %}

{% step %}

#### Change the SAM decision

If the site decides after making their decision to either Reject or Accept the Terms and Conditions, they need to tap the ‘0’ value to the right of “enablevhqsamdefault” and change it to a ‘1’ value using the keyboard.

Navigate back to the Home screen and tap “Reboot”. The Terms and Conditions will display upon starting up.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://commanderhelp.verifone.com/customer-documentation/petro-and-c-store/pin-pads/implementation-guides/m400/service-and-maintenance.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
