# Using the Charging Base

To use the charging base, you need only place the terminal(s) vertically on the base so the printer rests in the cradle at the top of the charging base.

### **A920**

### **A920 Pro**

{% hint style="info" %}
NOTE: The charging base should only be used to charge your terminal(s); it is not designed to be a storage location for the terminal(s).
{% endhint %}

If the status light remains blue after you place the terminal on the base, the terminal is not seated correctly, and not connecting to the base’s gold charging contacts.

{% hint style="warning" %}
IMPORTANT! Do not slide a terminal onto the base, as it can damage the gold charging contacts. Always place the terminal onto the base vertically, as shown below

### LED Status Light

The LED at the bottom edge of the charging base indicates the terminal’s charging status:

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://docs.payfacto.com/payfacto-knowledge/canada-doc-center/terminals/mobile/a920-a920-pro-accessories/pax-a920-a920-pro-terminal-charging-base-installation-guide/using-the-charging-base.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.
