Manage your Flex 4
Identify your Flex
Clover supports different Flex models, which are identified by their serial numbers. To find your serial number:
Open the receipt paper door.
Remove the paper.
Find the serial number (S/N) in the compartment. The serial number starts with the letter C and is followed by numbers that indicate the version and uniquely identify this device.
If you need to contact Clover Support, be sure to have the serial number handy when you call.
Charge your Flex
The Flex arrives with enough battery power to set it up and activate it. You can fully charge it whenever you have the time.
Hold the charging cradle upside down
Firmly insert the cord attached to the power brick into the charging port, and then thread the cord across and out the back.
Plug the power cord into the Flex and into a power outlet.
Set the Flex on top of the charging cradle.
Allow the device to charge until the indicator lights on the cradle turn solid green.
Replace the Flex battery
If you have a Flex model with a replaceable battery, follow these instructions to remove the old battery and replace it with a new one.
Power off the device.
Use a 1.5mm hex key or hex screwdriver to remove the two screws at the bottom.
Lift off the battery door from the bottom of the device.
Remove the two screws near the top of the battery.
Pull down gently to remove the battery
Insert the new battery and reattach the screws and cover.

Change the Flex SIM card
The Flex 4 comes with a pre-installed SIM card. If you’d prefer to use your own SIM card, you can replace the existing one. To access the SIM card, you'll need to remove the battery from the device first.

Use the Flex 4 printer
Load the receipt paper
Hold the Flex so that the back of the device faces you.
Open the paper compartment by pulling the top of the compartment door toward you.
Insert the paper roll so the end feeds straight out of the slot.
Close the compartment door until it clicks.
On the display screen, tap to print a test receipt.
Purchase new receipt paper
