Flow Keyboard Troubleshooting
Keyboard Status Indicator
The Status lights on the right and left keyboard can help diagnose potential issues.
With the Keyboard unplugged from power the status lights can show the following combinations:
1. Solid Green Light on Right and Left Side
This indicates that the right and left side are on, have good battery power and are bonded to each other.
2. Yellow light on Right and Left Keyboard (NOTE: the yellow color has greenish tint)
This indicates that the Right and Left Keyboard have become unpaired. Please follow the Right / Left Bonding instructions below.
3. Right side bright green and Left side Yellow
This indicates that the left side is sleeping and you should press on any key to wake it up.
Left keyboard not typing
If the left keyboard is not responding, it is likely of these issues:
1. The Left Keyboard is sleeping.
To wake the left keyboard press any key on the left side of the keyboard.
2. The Left Keyboard is out of charge.
To check the state of charge, follow the instructions in the "Checking Battery Charge" section below.
3. The Right and Left keyboard have become unbonded.
If the right and left keyboards have become unbonded, follow the "Right / Left Keyboard Bonding" instructions below.
Waking from Sleep
You must press keys on both the right and left keyboards to wake the Flow Keyboard from sleep. For the fastest wake up times, press a key on the right keyboard first, then the left keyboard.
Checking Battery Charge
Our battery indicator will show the state of charge for each half of the keyboard. The entire battery indicator area is a button which you can press which will show a series of green lights.
Turn the keyboard over and press firmly on the Battery Indicator Button.
Once pressed, the battery indicator will show the level of charge by displaying a series of bright green lights.
0 lights = 0% charged
1 light = 1% - 20% charged
2 lights = 21-40% charged
3 lights = 40-60% charged
4 lights = 60-80% charged
5 lights = 80-100% charged
If the Battery Indicator Button shows 0 lights or 1 light, please charge the keyboard. Using the supplied NUIO USB-C charging cable plug the end with 2 USB-C ports into each half of your Flow Keyboard, and the single USB-C end into a USB-C port on your Mac or a certified USB-C power supply that supplies voltage at a minimum of 5V and 1.5 amps.
Right / Left Keyboard Bonding
Press and hold these 4 keys for 10 seconds:
On the LEFT Keyboard: Function + Esc
AND
On the RIGHT Keyboard: Option (or Windows key for the Windows legends) + Bluetooth.
Make sure to press the “Option (Windows)” key before pressing the Bluetooth key.
Once the 10 seconds have passed, open a text program and press and hold the N and Z keys. You should see the “N” key first and after a few seconds, the “Z” key should show up. At that point the pairing process is complete and the left keyboard should be working again.
