Your device has 4 blue lights at the bottom of your card reader, here’s their function:
As soon as you switch on the SumUp Air, one LED will blink to indicate ‘power on’. It will continue to blink every 4 seconds to signal that the device is still on.
The LEDs also flash when a connection between the card reader and a smartphone/tablet is established.
If you’re processing an NFC transaction, a single LED will blink. Once the card is tapped on the reader, all 4 LED’s will blink.
The LEDs also signal the battery level of your reader. 4 LEDs indicate 100%, 3 indicate 75%, etc. If only one LED is blinking, it’s time to charge your card reader.
SumUp Air should be used in locations where the ambient temperature is between 0°C and 40ºC. Under the influence of low or high temperatures, your card reader may become blocked. To protect your SumUp Air from manipulation or tampering, we have designed it with security sensors in place. Make sure you always handle it with care and avoid force or impact to prevent the automatic security lock from being enabled. Once triggered, the device will be permanently locked.
To ensure optimal processing speed, make sure your card reader is always at a charge of 25% and higher. We recommend charging it on a monthly basis, even if you don’t use your SumUp Air regularly.
You can view your battery level on the screen of your reader and via the LED on the card reader (see ‘LED signals’ section for more information).
Charge your card reader with the Micro USB cable included in the package by connecting it to a computer or power supply. Don’t worry, you can still use your Air Card Reader while it is charging, and once it is at 100%, you can process up to 500 transactions before charging it again.
Your card reader requires a Bluetooth connection of 4.0 or higher. The SumUp App uses the internet connection from your smartphone or tablet, however, the file size of the data transferred between your device and card reader is very small and should not greatly affect your data plan.
