– Reconnecting your keyboard
—————————————————————————
Keyboard isn’t working
In order for your K480 keyboard to work with your computer, your computer must have built-in Bluetooth capability or be using a third-party Bluetooth receiver or dongle. The K480 keyboard isn’t compatible with a Logitech Unifying receiver, which uses Logitech unifying wireless technology.
If your system is Bluetooth-capable and the keyboard isn’t working, the problem is likely a lost connection. The connection between the K480 keyboard and the computer or tablet can be lost for several reasons, such as:
– Low battery power
– Using your wireless keyboard on metal surfaces
– Radio frequency (RF) interference from other wireless devices, such as:

– Wireless speakers
– Computer power supplies
– Monitors
– Cell phones
– Garage door openers

Try to rule out these and other possible problem sources that might be affecting your keyboard.

Keyboard frequently loses connection
If your keyboard frequently stops working and you keep having to reconnect it, try these suggestions:
– Keep other electrical devices at least 8 inches (20 cm) away from the Unifying receiver.
– Move the keyboard closer to the computer or tablet.

Before reconnecting your keyboard
Before you try to connect your keyboard again:
1. Check the battery power by turning the keyboard off and then back on again using the ON/OFF switch on the bottom of the keyboard. Notice the LED indicator color to the left of the ON/OFF switch. If the LED indicator is red, the batteries need to be replaced.
2. Try using the Windows key or type something to verify it’s working.
3. If it’s still not working, follow the link below to reconnect your keyboard.

Reconnecting your keyboard
To reconnect your keyboard, click the link for your device:
 – 360023422173 – Connect the K480 keyboard to a computer running Windows
 – 360023422173 – Connect the K480 keyboard to an iPad or iPhone
–  360023422173 – Connect the K480 keyboard to an Android tablet or smartphone

If you want to uninstall Logitech Options, so you can reinstall the software and start with new customized settings, you’ll need to delete the LogiOptions folder after you uninstall. The folder is at the following location:

– C:\Users\name\AppData\Roaming\Logishrd

NOTE:  This applies to standard account settings. If you’re logged in as an administrator, you can skip this step.

You can connect the K480 keyboard to an Android device running Android 3.2 and later. Here’s how:
1. On your Android device, go to Settings > Bluetooth to turn on Bluetooth.

2. Turn the keyboard on by sliding the power switch on the bottom of the keyboard over to the right.
3. Using the device memory wheel on the top left of the keyboard, select 1, 2, or 3. You can save up to three devices to memory on the keyboard.
4. At the top right of the keyboard, press and hold the PC button until the light to the left of the button rapidly blinks blue.
5. On your Android device, in the Bluetooth Settings screen, tap once on Logitech Keyboard K480 to select it.

6. On your keyboard, type the PIN code displayed on your device’s screen, and then press Enter.

NOTE:  Each connect code is randomly generated. Make sure you enter the one shown on your device’s screen.
7. Once you press Enter, the pop-up will disappear and the word Connected will show beside your keyboard in the Devices list.

8. Your K480 keyboard is now connected.

NOTES: Settings may vary between Android 3.0+ and 4.0+ devices. See your device’s user guide if you’re unable to pair the K480 keyboard.
9. If the K480 is already paired but having problems connecting, you can remove it from the device list and follow the instructions above to connect it.

With Logitech Options software, you can customize some of the function keys on your keyboard when you’re connected to a Windows 7 or Windows 8 computer.
For example, you can change what the F1-F5 function keys and Camera/Screenshot buttons do when pressed with the fn key. Each button or key will has a list of special functions you can assign to it.
You can get Logitech Options from your device’s main support page.

INTRODUCTION
This feature on Logi Options+ allows you to backup the customization of your Options+ supported device automatically to the cloud after creating an account. If you are planning to use your device on a new computer or wish to go back to your old settings on the same computer, log into your Options+ account on that computer and fetch the settings you want from a backup to set up your device and get going.

HOW IT WORKS
When you are logged into Logi Options+ with a verified account, your device settings are automatically backed up to the cloud by default. You can manage the settings and the backups from the Backups tab under More settings of your device (as shown):


Manage settings and backups by clicking on More > Backups:

AUTOMATIC BACKUP OF SETTINGS — if the Automatically create backups of settings for all devices checkbox is enabled, any settings you have or modify for all of your devices on that computer are backed up to the cloud automatically. The checkbox is enabled by default. You can disable it if you don’t want the settings of your devices to be backed up automatically.

CREATE A BACKUP NOW — this button allows you to backup your current device settings now, if you need to fetch them later.

RESTORE SETTINGS FROM BACKUP — this button lets you view and restore all the available backups you have for that device that are compatible with that computer, as shown above.
The settings for a device are backed up for every computer that you have your device connected to and have Logi Options+ that you are logged into. Every time you make some modifications to your device settings, they get backed up with that computer name. The backups can be differentiated based on the following:
1. Name of the computer. (Ex. John’s Work Laptop)
2. Make and/or model of the computer. (Ex. Dell Inc., Macbook Pro (13-inch) and so on)
3. The time when the backup was made
The desired settings can then be selected and restored accordingly.

WHAT SETTINGS GET BACKED UP
– Configuration of all the buttons of your mouse
– Configuration of all the keys of your keyboard
– Point & Scroll settings of your mouse
– Any application-specific settings of your device

WHAT SETTINGS ARE NOT BACKED UP
– Flow settings
– Options+ app settings

Some users have reported that their Logitech keyboard will not pair with their Android 7.x device after they’ve entered the pairing code.
– Users get a “connection timed out” error or no error message at all.
– Clearing the Bluetooth cache, power cycling the device, attempting to pair again, or pair to another Android 7.x device does not work.

If you are experiencing this issue, please try the following:
1. Boot your Andriod 7.x device into Safe Mode. This typically involves holding down the power button and volume key at the same time, but you should confirm the exact steps on your device manufacturer’s website.
NOTE: You’ll see an on-screen notification when the device is in Safe Mode.
2. While in Safe Mode, pair the keyboard with your device.
3. After the keyboard has successfully paired, restart your device normally. The keyboard should continue to be paired with your device. 

Starting with macOS High Sierra (10.13), Apple has a new policy that requires user approval for all KEXT (driver) loading. You may see a “System Extension Blocked” prompt (shown below) during the installation of Logitech Options or Logitech Control Center (LCC). 
If you see this message, you’ll need to approve the loading of the KEXT manually so that your device drivers can be loaded and you can continue to use its functionality with our software. To allow KEXT loading, please open System Preferences and navigate to the Security & Privacy section. On the General tab, you should see a message and an Allow button, as shown below. In order to load the drivers, click Allow. You may need to reboot your system so the drivers are properly loaded and the functionality of your mouse is restored.

NOTE: As set by the system, the Allow button is only available for 30 minutes. If it has been longer than that since you installed LCC or Logitech Options, please restart your system to see the Allow button under the Security & Privacy section of System Preferences.
 

NOTE: If you don’t allow KEXT loading, all devices supported by LCC will not be detected by software. For Logitech Options, you need to perform this operation if you’re using following devices:
– T651 Rechargeable trackpad
– Solar Keyboard K760
– K811 Bluetooth keyboard
– T630/T631 Touch mouse 
– Bluetooth Mouse M557/M558

Ideally, Secure Input should only be enabled while the cursor is active in a sensitive information field, such as when you enter a password, and should be disabled right after you leave the password field. However, some applications may leave the Secure Input state enabled. In that case, you may experience the following issues with devices supported by Logitech Options:
– When the device is paired in Bluetooth mode, it’s either not detected by Logitech Options or none of the software-assigned features work (basic device functionality will continue to work, however).
– When the device is paired in Unifying mode, it’s not possible to perform keystroke assignments.
If you encounter these issues, check to see if Secure Input is enabled on your system. Do following:
1. Launch Terminal from /Applications/Utilities folder.
2. Type the following command in Terminal and press Enter:ioreg -l -d 1 -w 0 | grep SecureInput

– If the command returns back no information, then Secure Input is not enabled on the system.  
– If the command returns back some information, then look for “kCGSSessionSecureInputPID”=xxxx.  The number xxxx points to the Process ID (PID) of the application that has Secure Input enabled:Launch Activity Monitor from /Applications/Utilities folder.
Search for PID which has secure input enabled.

Once you know which application has Secure Input enabled, close that application to resolve the issues with Logitech Options.

To begin troubleshooting, please select your operating system:
– Windows
– Mac

Windows
1. In the Device Manager, change the Bluetooth wireless adapter power settings: 
– Go to Control Panel > System and Security > System > Device Manager 
2. In Device Manager, expand Bluetooth Radios, right-click on the Bluetooth wireless adapter (ex. Dell Wireless 370 adapter), and then click Properties.
3. In the Properties window, click the Power Management tab and uncheck Allow the computer to turn off this device to save power. 
4. Click OK.
5. Restart your computer to apply the change.

Macintosh
1. Navigate to the Bluetooth preference pane in System Preferences: 
– Go to Apple Menu > System Preferences > Bluetooth
2. In the bottom-right corner of the Bluetooth preference window, click Advanced.
3. Make sure all three options are checked: Open Bluetooth Setup Assistant at startup if no keyboard is detected 
4. Open Bluetooth Setup Assistant at startup if no mouse or trackpad is detected 
Allow Bluetooth devices to wake this computer 
NOTE: These options ensure that Bluetooth-enabled devices can wake your Mac, and that the OS X Bluetooth Setup Assistant will launch if a Bluetooth keyboard, mouse or trackpad is not detected as connected to your Mac.
5. Click OK.

By default, the Num Lock on your keyboard is disabled each time Windows 10 boots up after a shutdown or restart.

To configure your operating system so that Num Lock stays on during startup, please contact professional support for your operating system. This requires advanced changes that need to be done under the guidance of a professional technician.

We are aware that after updating from macOS 10.12 Sierra to macOS Sierra 10.12.1, Logitech Options software does not detect supported Unifying devices on some systems. To fix this issue, unplug the Unifying receiver and then plug it back into the USB port. If Logitech Options still doesn’t detect the device, you may also need to reboot your system.

In most cases, the keyboard keeps disconnecting due to issues with the components (cables, ports, internal keyboard parts, etc.). Misconfigured power settings can also lead to power supply issues that result in a keyboard that doesn’t work properly.

Remember, you have to pair them first and the k480 has three (F1 thru F3) keys that allow you to interface to three different Bluetooth types devices. Could be that your desired connecting device is no longer paired and then make sure that the Flashing F3 key is paired for your desired device.

Press and hold the FN key, then press the F12 key: If the LED glows green, the batteries are good. If the LED blinks red, the battery level is low and you should consider changing batteries. You can also turn the keyboard off then back on using the On/Off switch on top of the keyboard.

The K480 should connect to your TV as long as it has Bluetooth input capability.
