Now, let's take a closer look at the display. Thanks to the handy icons it shows, it is easy to monitor the device's performance. For example, if conditioned AC power is supplied to your equipment, you will see a plug in the upper left corner of the screen. To its right, there are icons to display the item's load capacity and its battery charge level. The unit will show the number of events that occurred; special signs will appear when the unit is compensating for low voltage or it is providing a battery backup.

To get an excess to additional data and settings, you can download a PowerChute software; a cable to connect your PC to the unit's USB port is included in the box. On the back panel of the UPS, in addition to the outlets and a USB port, you will find surge-protected In/Out Ethernet and Coaxial ports.

Despite being that functional, the appliance is very simple to operate. There are only three buttons on its front panel:

• A Mute button will allow you to turn the audio alarms on and off.
• A Power On/Off button will help you activate the unit so that it receives the input AC power; in case the latter is not available, it will use the battery power. If you hold the button for two seconds, the device will not receive the input AC power; it will only provide surge protection.
• A Display button will help you get the desired information on the UPS performance; it will also allow you to switch the unit to a power-saving mode (in this mode, the LCD will light up when you press the button and darken after 60 seconds).
