# Handling and Storage

{% hint style="danger" %}
Proper handling of the device throughout delivery, assembly, shipping, installation, usage, and maintenance is very important. Not following the guidelines in this document could damage the device, render it inoperable, and/or violate the conditions of the warranty.
{% endhint %}

## Handling to Avoid Damage

Upon receiving the device, inspect it to make sure it originated from an authentic source and has not been tampered with. For details, see *D998200593 DynaFlex II Go Device Inspection Document*, available from MagTek.

From device delivery through assembly, shipping, installation, usage, and maintenance, the device must not be exposed to conditions outside the ratings in Appendix A Technical Specifications.

If the device is exposed to cold temperatures, adjust it to warmer temperatures gradually to avoid condensation, which can interfere with the operation of the device or cause permanent damage. Do not drop or shake the device.

For information about ongoing maintenance of the device, such as cleaning, see section 8 Maintenance.

## Handling to Avoid Accidental Tamper

DynaFlex II Go products implement active tamper detection, which uses a small amount of electricity even when the device is completely powered off. When unpowered by an external power supply, the device powers its active tamper detection circuitry using its non-rechargeable internal backup battery. This provides 5 years of backup shelf life across the entire life of the device. If the backup battery is allowed to completely discharge, the device’s tamper detection engages and locks down the device, and it must be returned to the manufacturer to reset.

To avoid accidental tamper events and to optimally condition the battery, follow these precautions:

* Temperature is the most critical factor in extending battery life and preserving battery charge. Store the device at the lowest reasonable temperatures within its specified storage temperature range (see Appendix A Technical Specifications). Storing at temperatures between -4°F to 113°F (-20°C to 45°C).
* Do not drop or shake the device.
* Do not attempt to disassemble the device.

## 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://developer.magtek.com/hardware/card-readers/mms-dyna-devices/dynaflex-ii-go/documentation/user-manuals/installation-and-operation-manual/handling-and-storage.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.
