Frequently Asked Questions¶

Backlight Stays On¶

Normally, the K800's backlight will turn off after 10 to 15 seconds, or whenever you've set it to go off.

Sometimes though, the keyboard may stay lit longer. This often happens when the keyboard is moved to a different location on the desk or to another desk entirely.

The reason for this is that the keyboard has a built-in system to detect your hands. When moved, it can take some time for the keyboard to perform this detection again.

Allow 3-5 minutes for the keyboard to go through its detection cycle. Then, the backlight should begin to switch off again in the amount of time expected.

Battery Life Information¶

Battery information

• Requires 2 AA NiMh batteries.
• Expected battery life is 15 hours to 10 days depending on backlight settings.

The keyboard has a standby mode to conserve power when not in use.

Note: The batteries aren't user replaceable.

At some point the batteries included must have changed because the one I own K800 model Y-R0011 has replaceable batteries.

Keyboard Wakes the Computer Even When It Is Set Not To¶

Symptom

After disabling the ability to wake up the system in Windows Device Manager, the mouse or keyboard still brings the system out of sleep mode.

Solution

Even if you bought a mouse-only or keyboard-only product, the receiver that came with it still enumerates for both the mouse and keyboard interfaces.

Example

If you have two mice attached, then you would need to uncheck the "Allow this device to wake the computer" option for both mice plus a keyboard in the Windows Device Manager.

Use the process below to identify and configure the devices to not wake up the system in Windows Device Manager.

Changing wake-up settings in the Device Manager

To change the wake-up settings in Windows Device Manager, you'll need to launch it through Computer Management and then make the selections.

• Click Start, right-click Computer, and then click Manage.
• Click Device Manager in the navigation pane on the left.
• Select and expand either the "Keyboards" or "Mice and other pointing devices" category.
• Right-click on the first entry and go to Properties > Details tab > Hardware IDs under the Property section.
• Make sure the Value section contains: HID\VID_046D&PID_C52B. If it doesn't, click Cancel and open the next mouse or keyboard entry in the list.
• Select the "Power Management" tab and uncheck the "Allow this device to wake the computer" check box.
• Repeat the same steps for all entries in both the "Keyboards" and "Mice and other pointing devices" categories.

Logitech Keyboard FN Key Behaviour on macOS or iOS¶

The FN key on Logitech keyboards, when connected to macOS or iOS, functions differently from the Fn/Globe key on Apple.

• On Logitech keyboards, the FN key is primarily used to access additional functions on the F-keys, such as adjusting the volume or using the media controls.
• On Apple keyboards, the FN/Globe key serves as a shortcut for specific system-wide functions, like activating Siri, changing input languages, and controlling other macOS features, with a more integrated role in Apple's ecosystem.

Logitech's keyboards do not send the Fn/Globe key keycode in a manner that is compatible with Apple's specific shortcuts. As a result, certain Apple functions, such as window tiling and other shortcuts reliant on the Fn/Globe key, are not supported by our keyboards.

Num Lock and Caps Lock indicators¶

Caps Lock indicators

On the K800 Keyboard itself, to determine if Caps Lock is on by checking the green indicator light in the top left corner of the Caps Lock button. If it is lit, Caps Lock is on and all the letters typed will appear in uppercase.

Another way to determine if the Caps Lock is on through the on-screen notification.

To determine on-screen if the K800 has Caps Lock on:

Note: You need to have Logitech SetPoint software installed in order to receive on-screen notifications.

• Caps Lock On: When the Caps Lock button is pressed and see the "Caps Lock On" message, all the letters typed will appear in uppercase.
• Caps Lock Off: When the Caps Lock button is pressed and see the "Caps Lock Off" message, unless using the Shift button, all the letters typed will appear in lowercase.

Num Lock indicator

With the K800 Keyboard, to determine if the Num Lock is on through the on-screen notification.

Note: You need to have Logitech SetPoint software installed in order to receive on-screen notifications.

To determine on-screen if Num Lock is on:

• Num Lock On: Press the Num Lock key at the top left of the keypad and see the "Num Lock On" message, using the keypad enters numbers.
• Num Lock Off: Press the Num Lock key above and to the left of the keypad and see the "Num Lock Off" message, the numbered keys on the keypad act as direction keys moving the cursor in the direction of the arrows printed on them.

Num Lock Disabled After Windows 10 Starts¶

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

To configure the 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.

NumPad/KeyPad is Not Working¶

• Make sure that the Num Lock key is enabled. If pressing the key once doesn’t enable Num Lock, press and hold the key for five seconds.
• Verify that the correct keyboard layout is selected in Windows Settings and that the layout matches the keyboard.
• Try enabling and disabling other toggle keys such as Caps Lock, Scroll Lock, and Insert while checking if the number keys work on different apps or programs.
• Disable Turn on Mouse Keys:
  1. Open the Ease of Access Center — click the Start key, then click Control Panel > Ease of Access and then Ease of Access Center.
  2. Click Make the mouse easier to use.
  3. Under Control the mouse with the keyboard, uncheck Turn on Mouse Keys.
• Disable Sticky Keys, Toggle Keys & Filter Keys:
  1. Open the Ease of Access Center — click the Start key, then click Control Panel > Ease of Access and then Ease of Access Center.
  2. Click Make the keyboard easier to use.
  3. Under Make it easier to type, make sure all checkboxes are unchecked.

• Make sure the keyboard drivers are updated. Learn how to do this in Windows by reading Update drivers manually in Windows - Microsoft Support.
• Try using the device with a new or different user profile.
• Test to see if the mouse/keyboard or receiver on a different computer.

Operating Distance¶

In ideal situations, the K800 can operate up to 30 feet (10 meters) with the receiver in clear sight of the keyboard and mouse.

If you are not getting this distance:

• Replace the batteries with a fresh set.
• Move devices such as cell phones, radios, wireless routers, microwaves, and other devices that emit radio waves or could cause radio interference (RF) away from the work area.

To determine if the environment is causing shorter than expected ranges, try using K800 in a different environment to see if the distance improves.

Supported Operating Systems¶

The K800 is supported by:

• Windows 7
• Windows XP
• Windows Vista

The K800 is not officially supported on Windows 98, Windows ME, Windows 2000, UNIX, GNU/Linux or Macintosh operating systems.

Logitech's keyboards are not supported on GNU/Linux. However, there is a few unofficial solutions that could work by following the post Pairing to a Logitech Unifying Receiver.

Toggle Between Multiple Languages on iPadOS with an External Keyboard¶

2. Slide the switch from "ON" to "OFF".

Note: The switch will have a red background showing on the right side and none of the battery indicator lights will be lit to the left of the switch.

Using K800 with a Different USB Receiver¶

The K800 ships with the new Logitech Unifying USB receiver.

You can only connect the K800 with Unifying USB receivers that display the Unifying logo.

Note: Although the device may be supported by the Unifying receiver, SetPoint and/or Logitech Control Centre (LCC) support will depend on the specific product.

Using the FN and F1-F12 Keys¶

The K800 Keyboard's function keys, or F-keys, have two modes:

• Normal. By default, the function keys perform tasks based on the operating system and application you're using. To use a function key in its normal state, you press it by itself.
• Enhanced. The function keys are pre-programmed to perform certain tasks when you press them at the same time as the FN key (shown below). For example: Press and hold the FN key (A) and the F1 key (B) to launch an Internet browser.

Using the Logitech SetPoint Mouse and Keyboard Software, you can change the pre-programmed function for each key. You can also swap the modes, so the enhanced functions work without having to press the FN key. See the "Programming function keys" section of answer 360023230934 for instructions.

The enhanced functions are listed below:

Warning Message When Logitech Device is Connected to iPadOS¶

When you connect the Logitech device, you might see a warning message.

If this happens, make sure to connect only the devices you’ll be using. The more devices that are connected, the more interference you might have between them.

Wireless Product Not Working Properly When Using a USB 3.0 Device¶

When using a USB 2.0 2.4GHz wireless peripheral device (such as a mouse, keyboard, or headphones) with a PC that also has a USB 3.0 peripheral device plugged in, you may experience erratic operation caused by interference. This is especially likely to happen when using USB 3.0 remote hard drives or flash drives.

This interference may result in:

• Delayed response to mouse or keyboard inputs
• Missing keyboard characters or mouse commands
• Decreased operating distance between the USB 2.0 wireless device and its receiver

There are some techniques that can help early adopters of USB 3.0 to mitigate potential problems with their existing 2.4GHz wireless devices:

• If the PC has multiple USB 2.0 connectors available, separate the USB 3.0 and USB 2.0 receivers by as much distance as possible. For example, if the PC has a choice of USB 2.0 connectors, use the one on the opposite side of the PC from the USB 3.0 connector.
• Position the USB 2.0 receiver as close as possible to the wireless peripheral (mouse, keyboard, headphones, etc.).
• Use a standard, USB-extender cable to position the USB 2.0 wireless receiver as far away as possible from the USB 3.0 connector.

A USB-extender cable is available for Logitech customers who are experiencing this problem.

Note: A USB 3.0 connector sometimes referred to as Super Speed USB or SS, normally has a blue plastic insert in the connector. Unlike a USB 2.0 connector which has 4 pins within the connector, a USB 3.0 connector has 9 pins.

Move the USB 2.0 wireless receiver to the opposite side of the computer.

Make sure the USB 2.0 wireless receiver is in the USB 2.0 connector closest to the wireless peripheral.

Use a USB extended cable to position the wireless receiver as far away from the USB 3.0 peripheral as possible.
