# Device Setup

This section outlines the setup procedures for the e235 device.

## Terminal Location

Following are guidelines used to select an ideal location for the terminal.

### Ease of Use

* Select a location convenient for both merchant and the cardholder.
* Select a flat support surface, such as a countertop or table, or mount it on a mounting stand supplied by Verifone.
* Select a location near a power outlet, POS (Point-of-Sale), ECR (Electronic Cash Register), or computer connected to the terminal. Do not string cables or cords across a walkway for safety.

### Environmental Factors

* Select a flat support surface, such as a countertop or table, to keep the device safe in between uses.
* Do not use the device where there is high heat, dust, humidity, moisture, or caustic chemicals or oils.
* Keep the device away from direct sunlight and anything that radiates heat, such as a stove or motor.

### Personal Security Considerations

The e235 is a handover device. Always exercise extreme caution when conducting transactions, especially during PIN entry.

* Hand over the e235 device directly to the cardholder for PIN entry.
* Encourage the cardholder to hold the e235 device closer to avoid others from seeing the information entered.

### Electrical Considerations

* Avoid using this product during electrical storms.
* Avoid locations near electrical appliances or other devices that cause excessive voltage fluctuations or emit electrical noise (for example, air conditioners, electric motors, neon signs, high-frequency or magnetic security devices, or computer equipment).
* Do not use the terminal near water or in moist conditions.
* Disconnect the device from its POS terminal before cleaning.

### Contactless Considerations

Avoid having metallic objects in the proximity of a contactless antenna. If you need to mount the terminal to vertical or inclined surfaces, use a flat, non-metallic mounting plate.

{% hint style="warning" %}
Using an enclosed metal frame or mount may negatively affect contactless performance.

*L'utilisation d'un cadre métallique fermé ou de montage peut affecter négativement contact performance.*
{% endhint %}

## PIN Protection Measures

Use the following techniques to provide effective screening of the PIN entry during the PIN entry process. You can use these methods in combination, although in some cases a single method might suffice.

* Position the device such a way as to block visual observation of the PIN entry process.
* Position the angle of the device in such a way that PIN spying is difficult.
* Position in-store security cameras so that the PIN entry keypad is not visible.
* If the device is to be mounted vertically in a kiosk, the e235 device must be mounted according to the following guidelines to reduce the possibility of PIN spying.

### ICCR Protection for Unattended Use

Following are the guidelines to protect ICCR (Internal Contact Card Reader) for unattended use.

* The smartcard slot must be in full view of the cardholder during card insertion so that any suspicious or foreign objects at the opening are noticeable.
* For unattended payment terminal designs where the smartcard slot cannot be positioned straight (horizontal) to the cardholder, the device must be mounted such that the installation height ensures a sufficient view of the card slot entry area.
* The maximum downward angle of the smartcard slot from the horizontal position should be no more than 70 degrees.

## Initial Battery Charging

After unpacking your e235 device, connect the power pack to the unit for eight hours or until fully charged. The battery has a safety circuit to protect the Li-ion cells from overcharging and over-discharging. If the battery is over-discharged, the safety circuit shuts down the battery. The battery must then be recharged to restore operation.

## Starting Up and Shutting Down

The e235 device starts up differently depending on how it is powered.

* The device starts up automatically when the e235 is connected to a nonbattery power source, regardless of the battery charge state.
* To manually power up, hold the green key down for about 4 seconds until the device displays the startup screen.

{% hint style="info" %}
The 4-second power-up delay prevents device startup if the green key is accidentally held down. The time required to hold the green key down to power up the device is configurable.
{% endhint %}

The device lights up once the power is on.

{% hint style="info" %}
The Verifone copyright screen starts and displays a unique copyright screen. If the terminal comes pre-loaded with an application, this starts after the initial Verifone copyright screen and usually displays its copyright screen.
{% endhint %}

To manually shut down, hold the red key down for about 4 seconds until the device screen stays blank.

## Using the Battery

The e235 device uses a single-cell Li-ion battery with the following features:

* The battery has a safety circuit that:
  * Prevents cell damage from overcharge, over-discharge, or overheating.
  * Activates when the battery is left in an unused state for an extended period.
* The battery provides power to the security circuit when the e235 device has no external power source.
* Li-ion batteries are not affected by shallow charging.

Follow these best practices for best function:

* Conserve battery power by turning the e235 device off when not in use.
* Keep the Li-ion battery inserted in the device and power up the device periodically to check the battery charge. Do not let the battery charge fall below 10% for an extended period of time as this may permanently diminish battery capacity.
* Recharge the battery by connecting the USB-C end of the power pack to the device and plugging the other end of the power pack into a wall outlet.

{% hint style="info" %}
The e235 device will only operate when the battery is installed unless connected to AC (Alternating Current) power, for example, in a stand.
{% endhint %}

{% hint style="info" %}
The e235 device automatically shuts off when the battery reaches the critically low charge state. If this occurs, the battery must be recharged for a minimum of 1/2 hour before it can power the device. It may take several recharges attempts to reset the safety circuit when charging a battery that has been discharged below this critical state.
{% endhint %}

Dispose of the battery pack/coin cell in accordance with all national, state, and local laws and regulations as regionally required. Some batteries may be recycled and may be accepted for disposal at local recycling centers. CAUTION: There is a risk of explosion if the battery is replaced by an incorrect type.

* Disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery, that can result in an explosion.
* Leaving a battery in an extremely high temperature surrounding environment that can result in an explosion or the leakage of flammable liquid or gas.
* A battery subjected to an extremely low air pressure that may result in an explosion or the leakage of flammable liquid or gas.

### Battery Life

Charging and discharging the e235 battery hundreds of times will wear out the battery. Significantly reduced operating times indicate the need for battery replacement (see [Accessories and Cables](/hardware-products/hardware/engage-devices/exxx-series/e235/e235-installation-guide/accessories-and-cables.md) for ordering information).

### Charging the Battery

After installing the battery, the e235 device can be connected to the optional power pack or charged with a wireless charger.

{% hint style="danger" %}
Do not dispose of batteries in a fire. Li-ion batteries must be recycled or disposed of properly. Do not dispose of Li-ion batteries in municipal waste sites.

*Ne jetez pas les piles dans le feu. Les batteries Li-ion doivent être recyclées ou éliminées correctement. Ne jetez pas les batteries Li-ion dans les décharges municipales.*
{% endhint %}

{% hint style="warning" %}
