After 20 seconds, release the button and wait 10 seconds.
Press the button again to turn the Square Reader on and observe any lights on the Square Reader.
If the lights on the Square Reader turn on, you’re all set. If the lights don’t turn on, try again. Make sure to firmly press and hold the Square Reader's button for a full 20 seconds.
Charging and Powering Your Square Devices Safely
Square cables and wall chargers are tested thoroughly and adhere to government standards. To keep you safe and your devices working properly, we recommend you follow these guidelines:
Always charge your Square products with the included cable and certified USB charging sources.
Store your devices and cables in a safe place away from moisture, extreme temperatures, and debris as these can cause fire, electric shock, injury, or damage to your Square product.
Always charge your devices in a dry environment away from all sources of moisture.
Inspect your cables and devices for any damage or debris that could interfere with the proper performance of your Square products. If you see any debris or damage to a cable or any connectors, discontinue use and contact Square Support for a replacement.
Make sure all connections are fully engaged before charging your device.
Always plug and unplug your cables and chargers by holding onto the end of the cable.
Keep the connectors free of foreign objects and debris.
Always charge your device in a well-ventilated area.
If your Square Reader gets wet, immediately power off the device, holding down the power button for at least fifteen seconds. Remove moisture by allowing Square Reader to dry out with the card slot facing down.
Protect Your Square Reader
Get the most life out of your Square Reader by avoiding damage to the hardware. Certain attachments and environments can cause damage to Square Reader over time and shorten the lifespan of your device. To protect your Square Reader from everyday wear and tear, we recommend using the compatible cases, accessories, and docks featured in Square Shop. These cases fit a variety of mobile phones and tablets.
Avoid using Square Reader in wet environments, and avoid getting water or liquid in the card slot. Taking insert payments with wet payment cards can also cause water damage.
Do not use strong magnets, hook-and-loop fasteners (like Velcro), adhesive, or mounting hardware not tested by Square to frequently mount and unmount Square Reader. The use of third-party accessories not tested by Square to secure Square Reader to surfaces can add tension or pressure to the device, which can cause damage.
Move Square Reader away from sources of Bluetooth interference, such as near microwave ovens, cordless phones, fluorescent lights or on a metal table.
