How to Work the Touchpad for an ACK-540

Updated July 20, 2017

The Keysonic ACK-540 keyboard is a mini wireless keyboard that has a touchpad built in. This unit is excellent for use with HTPCs, rack-mounted hardware and for presentations in conference rooms, as it can function up to 33 feet away from the computer it is connected to. The built-in touchpad renders a mouse unnecessary, making this unit very convenient. Installation and use of the unit is very quick, as no drivers are required for Windows 98SE, Millennium Edition, 2000, XP, Vista or Windows 7.

Plug the USB receiver into an available USB port on the computer.

Remove the battery cover on the back of your keyboard unit.

Insert four AAA batteries oriented as drawn on the unit.

Replace the battery cover.

Turn on the keyboard. The unit is programmed for immediate synchronisation so you should not have to do anything more.

Lightly press your finger against the touchpad and move it around. The cursor on the screen will follow your finger motions.

Slide your finger up and down the far right side of the touchpad to scroll through long pages.

Tap or double-tap the trackpad with your finger to simulate the clicks of a left mouse button. You also can use the buttons directly below the touchpad as mouse buttons.

Double-tap the touchpad leaving your finger down after the second tap. This will select or grab an object like an icon or a window. Slide your finger around to drag the item. This can be used to resize windows or move objects.
