Frequently Asked Questions - XKK400CWB-IT Hamlet
How do I connect the keyboard to my computer?
Insert the USB receiver into an available USB port on your computer. Install two AAA batteries in the keyboard (observe polarity), and slide the power switch to ON. The keyboard will automatically pair with the receiver. If not, press the connect button on both the receiver and the keyboard; then release after indicator light flashes. It is ready for use with Plug and Play.
Why is my keyboard not responding?
First, check the batteries and the power switch. If they are fine, reinsert the USB receiver into a different USB port. Make sure the keyboard is within 10 meters of the receiver and that there are no obstacles. If necessary, reconnect with the connect button. Also check for possible interference from other wireless devices.
How do I replace the batteries?
Turn the keyboard over and slide the battery cover off. Remove old batteries and insert two new AAA batteries following the + and - signs. Replace the cover. After battery replacement, the keyboard will operate immediately.
Does this keyboard work with tablets or smartphones?
The keyboard is designed for PCs but can be used with mobile devices via an OTG adapter if the device supports USB HID. For compatible tablets and phones, plug the USB receiver into the adapter. Some on-screen keys (like the Windows key) may not function.
How do I clean and maintain the keyboard?
Turn off or disconnect the keyboard. Use a soft dry cloth or a small brush to remove dust and dirt. For stubborn marks, slightly dampen the cloth (do not soak). Avoid using solvents or spraying liquids directly. Keep the keyboard in a dry, cool place.
How do I use the multimedia keys?
The top row of keys includes multimedia shortcuts: play/pause, stop, previous/next track, volume down/up, and mute. Simply press the corresponding key to control your media player. Some functions may work only in supported applications; on certain systems, press Fn + F1-F12 to access them.
What is the battery life?
An average user can expect up to 12 months of battery life from a single set of AAA batteries. Actual duration depends on daily usage, typing habits, and battery quality. Using alkaline or lithium batteries is recommended for the longest lifespan.
Is the keyboard compatible with macOS?
Yes, the keyboard works with macOS. The Windows key is mapped to the Command function; the Alt key acts as the Option key. Most standard shortcuts are similar. You can adjust modifier keys in System Preferences if needed.
How do I reset the keyboard if it stops working?
Remove both batteries and unplug the USB receiver. Wait 30 seconds, then reconnect the receiver, reinsert the batteries, and turn on the keyboard. Press the connect button on the receiver and the bottom of the keyboard to force a new pairing. This resolves most connection issues.
Can I use the keyboard while it is charging?
This keyboard is powered by disposable AAA batteries, not rechargeable; therefore, it does not have a charging function. If you want a rechargeable solution, you can use rechargeable AAA batteries (NiMH) and charge them with an external charger.
