VS-88H2A –Introduction

Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world

of unique, creative, and affordable solutions to the vast range of problems that confront the

video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we

have redesigned and upgraded most of our line, making the best even better!

Getting Started

We recommend that you:

•Unpack the equipment carefully and save the original box and packaging materials for

possible future shipment.

•Review the contents of this user manual.

Go to www.kramerav.com/downloads/VS-88H2A to check for up-to-date user manuals,

application programs, and to check if firmware upgrades are available (where appropriate).

Achieving Best Performance

•Use only good quality connection cables (we recommend Kramer high-performance,

high-resolution cables) to avoid interference, deterioration in signal quality due to poor

matching, and elevated noise levels (often associated with low quality cables).

•Do not secure the cables in tight bundles or roll the slack into tight coils.

•Avoid interference from neighboring electrical appliances that may adversely influence

signal quality.

•Position your Kramer VS-88H2A away from moisture, excessive sunlight and dust.

Safety Instructions

Caution:

•This equipment is to be used only inside a building. It may only be connected to other

equipment that is installed inside a building.

•For products with relay terminals and GPI\O ports, please refer to the permitted rating

for an external connection, located next to the terminal or in the User Manual.

•There are no operator serviceable parts inside the unit.

Warning:

•Use only the power cord that is supplied with the unit.

•Disconnect the power and unplug the unit from the wall before installing.

•Do not open the unit. High voltages can cause electrical shock! Servicing by qualified

personnel only.

•To ensure continuous risk protection, replace fuses only according to the rating

specified on the product label which is located on the bottom of the unit.
