# Troubleshooting Guidelines

This chapter compiles common instances of malfunctions that may arise during the operation of your device, along with the corresponding steps to address them. The troubleshooting guidelines outlined in the subsequent sections are incorporated to facilitate the effective installation and configuration of the device. Should you encounter challenges in operating your unit, please refer to these troubleshooting examples. If the issue persists despite following the guidelines provided or if the problem is not covered, kindly reach out to your local Verifone representative for further assistance.

{% hint style="info" %}
The device is equipped with tamper-evident labels and does not contain any user-serviceable parts. It is crucial not to attempt to disassemble the unit under any circumstances. Only perform adjustments or repairs explicitly outlined in this guide. For any other services, please contact your local Verifone service provider. Utilizing services from unauthorized parties may potentially void any existing warranty.
{% endhint %}

{% hint style="warning" %}
All units require the use of a power supply. Only use a Verifone-supplied power pack. Using an incorrectly rated power supply may damage the unit or cause it to malfunction. Ensure that the power supply used to power the unit matches the specified requirements on the back of the unit (refer to Specifications for detailed power supply specifications) before troubleshooting. If not, obtain the appropriately rated power supply before continuing with troubleshooting.

*Toutes les unités nécessitent l’utilisation d’une alimentation. Utilisez uniquement un bloc d'alimentation fourni par Verifone. L’utilisation d’une alimentation mal calibrée peut endommager l’appareil ou l’empêcher de fonctionner correctement. Assurez-vous que l'alimentation électrique utilisée pour alimenter l'unité correspond aux exigences spécifiées à l'arrière de l'unité (voir Spécifications pour les spécifications détaillées de l'alimentation électrique) avant le dépannage. Dans le cas contraire, procurez-vous une alimentation électrique appropriée avant de poursuivre le dépannage.*

## Device Does not Start

If the device does not start:

* Ensure that the device is plugged into a dedicated power source.
* Verify all the cable connections including the proper insertion of the power cable connector.
* If the problem persists, reach out to your local Verifone representative for assistance.

## Blank Display

When the device display is blank:

* If the device display appears dark, tap the screen. If the unit is in screen-saver mode, touch the screen to activate.
* If the display shows incorrect or unreadable information, inspect all cable connections. In case the problem persists, reach out to your local Verifone representative for assistance.

## Transactions Fail to Process

Multiple factors could be causing the unit to fail in processing transactions. Utilize the following steps to troubleshoot and identify the root of the failures.

### Checking Magnetic Card Reader

To check the magnetic card reader:

{% stepper %}
{% step %}

### Perform a transaction using distinct cards

Perform a transaction using one or more distinct magnetic stripe cards to rule out the possibility of a faulty card.
{% endstep %}

{% step %}

### Ensure cards are swiped correctly

Ensure that you are swiping cards correctly.
{% endstep %}

{% step %}

### Process a manual transaction

Process a transaction manually using the keypad instead of the card reader. If the manual transaction is successful and the issue persists with the card reader, it may indicate a problem with the card reader itself.
{% endstep %}

{% step %}

### Contact your local Verifone representative

If the problem persists, reach out to your local Verifone representative.
{% endstep %}
{% endstepper %}

### Checking Smart Card Reader

To check the smart card reader:

{% stepper %}
{% step %}

### Execute a transaction using various smart cards

Execute a transaction using various smart cards to eliminate the possibility of a faulty card.
{% endstep %}

{% step %}

### Verify card insertion

Verify that the card is inserted correctly.
{% endstep %}

{% step %}

### Check SIM card insertion

Ensure the SIM cards are appropriately inserted into the designated slots and are securely placed.
{% endstep %}

{% step %}

### Contact your local Verifone representative

If the issue persists, get in touch with your local Verifone representative.
{% endstep %}
{% endstepper %}

### Checking CTLS Reader

To check the CTLS reader:

Make sure there are no obstructions between the contactless logo and the card, ensuring a clear path between the contactless reader and the actual card for a seamless transaction.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.verifone.com/hardware-products/hardware/victa/victa-countertop/victa-countertop-installation-guide/troubleshooting-guidelines.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
