Install KensingtonWorks™ software and enhance productivity by customizing workflow options per application for virtually endless function combinations.
Kensington takes pride in making our comprehensive installation guides easy to follow, with simple illustrations and step-by-step instructions. This guide will walk you through setup and help you get to know your new mechanical keyboard.
A: You can connect up to three devices — one via the USB Nano Receiver that stows inside the trackball body and two additional connections via Bluetooth® 1 / Bluetooth® 2.
A: The TB550 does not support wired connection. The cable is just for charging.
A: The TB550 Trackball only supports Bluetooth® Low Energy (Bluetooth® 4.0 or later). The Legacy Bluetooth® 3.0 is not supported.
A: You can clean the ball using the following procedures: 1. Remove the ball from the socket using the eject button on the bottom of the trackball frame.
2. Clean the ball and trackball frame with a damp cloth or rubbing alcohol and allow them to dry.
3. Lubricate the ball with a non-acidic lotion. We recommend using an oil-based lotion (such as Vaseline® lotion) for the best result. Evenly rub a pea-sized amount of lotion into the palms of your hands and roll the ball across the lotion on your hands until the ball is well lubricated.
4. Gently push the ball back into the socket. If the ball feels a little sticky, simply roll it around in the socket until it moves freely.
A: The dimensions of the TB550 Trackball are 138.16 mm x 93.44 mm x 50.1 mm (5.44” x 3.68” x 1.97”).
A: Yes. With KensingtonWorks™ software, the user can customize shortcuts when the scroll wheel is tilted left/right.
A: Yes. It can scroll both vertically and horizontally. But whether the horizontal scroll can work or not will depend on whether the application itself can support horizontal scrolling. Currently, horizontal scrolling is supported for Excel by default.
A: The TB550 Trackball has a rechargeable battery. With one single charge, the trackball can provide up to 4 months of battery life. However, the actual battery life will vary by use.
A: The trackball is a Plug & Play device and for basic functionality does not require drivers. For customization, free downloadable KensingtonWorks™ software is available on the Kensington website. KensingtonWorks™ provides a personalized experience, letting you assign a variety of functions (including shortcuts) to a total of seven buttons (left click, right click, middle click, backward, forward, left tilt, and right tilt), and adjust cursor and scrolling speed.
A: The TB550 Trackball is designed to work best for right-handed users.
A: The TB550 Trackball supports 4 DPI options: 400/800/1200/1600. There is a DPI switch button and a DPI indicator located on the bottom of the trackball.
A: Yes. Both the trackball itself and the free downloadable KensingtonWorks™ software support macOS. You can connect the trackball to your MacBook via either Bluetooth® or the 2.4GHz wireless receiver. Please note that you might need a USB-A to USB-C adapter (not included) for 2.4GHz wireless connection if there is no USB-A port on your MacBook. Please also note that backward and forward buttons do not work under macOS by default.
A: The left click, right click, middle button (by pressing down the scroll wheel), backward, forward, left tilt, and right tilt buttons are all customizable via KensingtonWorks™ software.
