Troubleshooting 

How can users check a connected 
device? 

Users can check a connected device by pressing the Power Switch.  The 
LED indicator light will flash.  For example, LED is blue, and turns on once 
for 1 second when USB is active.  

The keyboard becomes disconnected 
when pressing Fn + Q.  

Fn + Q is used when pairing a new device.  In this state, if users press Fn + 
X, the pairing to new device will be cancelled and returns to the last 
connection. 

What power supply is being used when 
the keyboard is plugged to the USB 
cord but also Bluetooth?   

If a keyboard is connected with both the USB cord and Bluetooth, the 
default power supply will come from the USB connection. 

When the USB cable is plugged in and 
being used as the power supply 
(battery is low), the Bluetooth 
connection does not work. 

When users connect the USB cable for battery supplying, the Bluetooth 
connection is temporarily disconnected due to switching of the internal 
circuit. However, when the battery has enough charge for Bluetooth 
connection, it will be reconnected afterwards. 

Users cannot log in to macOS while 
using Bluetooth  

This can happen when FileVault is ON in the Security & Privacy settings 
under System Preferences of the Apple menu. In this case, type you’re 
your keyboard on your mac or connect the HHKB using the USB 
connection.  Please note that you will need to restart and log-in to your 
computer before being able to use HHKB in Bluetooth mode. 

It is invalid even though pressing short 
cut keys (e.g.: Fn + Ctrl + 1, and etc.) 

Please press the keys in the order: Fn -> Ctrl -> Number, etc. to use the 
combination of short cut keys.
