Introduction

The LKV-248AUSK provides Audio&Mic switching to offer

you uninterrupted multimedia experience with KVM Switching.

With its multi-platform support for PC and Macintosh G3/G4,

iMAC, this KVM Switch allows you to access, control, boot

and reboot multiple USB-enabled multimedia computers

using only one keyboard, video, mouse and a speaker set

and microphone. Built-in with a 4-port USB Hub, it is designed

specifically for sharing your USB keyboard, mouse and other

USB devices with four USB-enabled PCs.

Before you install

The default setting of LKV-248AUSK is appropriate for most

systems. In fact, you do not need to configure the KVM

Switch before installation. Yet particular caution has to be

taken before installation:
