# Maintenance and Cleaning

## Maintenance

Treat your V200c and V400c terminals with care. They have no user-serviceable parts.

The following suggestions will help you protect your warranty coverage.

* Do not store the device in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics.
* Do not store the device in cold areas. When the device returns to its normal temperature, moisture can form inside the device and damage electronic circuit boards.
* Do not drop, knock, or shake the device. Rough handling can break internal circuit boards and fine mechanics.

These suggestions apply equally to your device, as well as any of its attachments or accessories. If your device is not working properly, take it to the nearest Verifone-authorized service provider for servicing or replacement.

## Cleaning

The following suggestions and cautions will help you keep your terminal clean.

### Cleaning the Terminal

To clean the device, use a clean cloth slightly dampened with water and a drop or two of mild soap. For stubborn stains, use alcohol or an alcohol-based cleaner.

{% hint style="warning" %}
Never use thinner, trichloroethylene, or ketone-based solvents – they can deteriorate plastic or rubber parts.

Do not spray cleaners or other solutions directly onto the keypad or device display.

*Ne jamais utiliser de diluant, le trichloréthylène ou des solvants à base de cétone - ils peuvent détériorer les pièces en plastique ou en caoutchouc.*

*Ne pulvérise pas de nettoyants ou d'autres solutions directement sur le clavier ou sur lécran de l'appareil.*
{% endhint %}

### Cleaning the MSR

Dirt accumulation can lead to MSR reading problems unless you clean the magnetic stripe reader (MSR) on a regular basis (daily to once a week, depending on usage).

Clean the MSR using commercially available card reader cleaning cards, or using Verifone's recommended MSR-cleaning card (PN 02746-02).

{% hint style="info" %}
If using a commercially available cleaning card use ONLY an approved MSR cleaning card made specifically for POS MSR Card reader terminals or Petroleum MSR card readers.
{% endhint %}

### Cleaning the SCR

Do not attempt to clean the smart card reader (SCR). Doing so may void any warranty. For smart card reader service, contact your Verifone distributor or service provider.

{% hint style="warning" %}
If you find foreign objects in the SCR, send your terminal to a Verifone authorized repair center.

Do not use Verifone's recommended MSR-cleaning card (PN 02746-02) or commercially available card reader cleaning cards with the SCR.

*Si vous trouvez des objets de valeur dans le SCR envoyez votre terminal à centres de réparation autorisé Verifone.*

*N'utilisez pas la carte de nettoyage MSR recommandée par Verifone (réf. 02746-02) ou les cartes de nettoyage MSR de lecteur de cartes disponibles dans le commerce avec le SCR.*
{% endhint %}

## Additional Safety Information

The following is additional information for your safety in using this device.

{% hint style="danger" %}
When using the device in areas with potential risk of explosion, such as petrol stations, follow the advice of all signs and instructions. If there has been a leak, do not use this device.

*Environnements Potentiellement Explosifs — Lors de l'utilisation de l'appareil dans des zones à risque d'explosion, telles que les stations-service, conformez-vous à tous les panneaux et instructions. N'utilisez pas cet appareil s'il y a eu une fuite.*

## 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.verifone.com/hardware-products/hardware/engage-devices/vxxx-series/v200c/v200c-installation-guide/maintenance-and-cleaning.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.
