Logitech K480 Mode d'emploi
TROUBLESHOOTING
I can’t pair the keyboard with my device.
Your keyboard only connects to Bluetooth wireless–enabled devices. Confirm that the device
you’re trying to pair with is Bluetooth wireless–capable. Note: The Logitech Keyboard K480 is
not compatible with a Logitech Unifying receiver based on different wireless technology.
Restart the device and try pairing it with the keyboard again on the original channel or another
channel.
Note: On a Windows computer, a new Bluetooth wireless connection will sometimes require
additional software updates—a process that may still be ongoing after a message appears
indicating a successful completion. Wait at least 20 minutes after pairing to make sure all
updates are completed before restarting the computer.
Confirm that the device is configured to accept Bluetooth wireless connections. (Windows)
Go to Bluetooth Devices > Open Settings and select the following checkboxes:
Allow Bluetooth devices to find this computer
Allow Bluetooth devices to connect to this computer
Alert me when a Bluetooth device wants to connect
Confirm that your computer, tablet, or smartphone is compatible with the Logitech Keyboard
K480. (See COMPATIBLE DEVICES.)
Make sure your computer, tablet, or smartphone supports an external keyboard (HID profile).
Check the user manual that came with the device or contact the manufacturer.
My keyboard isn’t working.
Confirm the correct channel is selected.
Press any key to wake the keyboard from sleep mode.
Turn the keyboard off and back on.
Turn Bluetooth wireless off and restart the computer. (Windows)
On the device:
Go to Bluetooth Wireless settings and turn off Bluetooth Wireless.
Restart the device and turn on Bluetooth Wireless.
Reconnect the keyboard.
Replace the keyboard batteries.
Confirm that the keyboard is paired with the device.
Pair the keyboard again with your computer, tablet, or smartphone.
On the device:
Go to Bluetooth Wireless settings and “forget” the Logitech Keyboard K480.
Turn off Bluetooth Wireless.
Restart the device and turn on Bluetooth Wireless.
Pair the device and keyboard again, following the steps in FIRST-TIME SETUP, “Pair the
keyboard with a device.”
My keyboard stopped working, or works only intermittently.
If your device is Bluetooth wireless–capable, this problem is likely caused by a lost Bluetooth
wireless connection. Several environmental factors can cause the connection between the
Logitech Keyboard K480 and a computer or mobile device to fail.
Check the keyboard batteries.
Make sure your keyboard isn’t resting on a metal surface that can interfere with a
Bluetooth wireless signal.
Verify that another wireless source isn’t interfering with the Bluetooth wireless signal.
Possible sources of interference include wireless speakers, a computer power supply, a
display monitor, cell phones, and garage door openers.
Make sure other electrical devices are at least 8 inches (20 cm) from your keyboard and
the computer or mobile device.
Try moving the keyboard closer to the computer or mobile device.
My keyboard doesn’t work after the connected PC wakes from sleep mode.
On the PC, change the Bluetooth wireless adapter power settings:
Go to Control Panel > System and Security > System > Device Manager.
In Bluetooth Radios, right-click on the Bluetooth wireless adapter (for example, Dell Wireless
370 adapter) and click Properties.
In the Properties window, click the Power Management tab and uncheck Allow the computer to
turn off this device to save power.
Click OK to save the settings and restart the PC.
The characters I’m typing don’t match the key labels.
Make sure you used the correct Bluetooth wireless connect button to pair the keyboard
with your device.
Review the instructions in FIRST-TIME SETUP, “Pair the keyboard with a device.”
When you select a paired device with the selection dial, the status light next to the connect button
you used for pairing starts blinking. If you used the wrong connect button, pair the device again
by holding down the other connect button until its status light next starts blinking.
