2 Getting Started

We recommend that you:

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

materials for possible future shipment

firmware upgrades are available (where appropriate).

2.1 Achieving the Best Performance

To achieve the 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 VM-24H away from moisture, excessive sunlight and

dust

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

connected to other equipment that is installed inside a building.

3.2 Using the IR Transmitter

You can use the RC-IR3 IR transmitter to control the machine via the built-in IR

receiver on the front panel or, instead, via an optional external IR receiver (Model:

C-A35M/IRR-50). The external IR receiver can be located up to 15 meters away

from the machine. This distance can be extended to up to 60 meters when used

with three extension cables (Model: C-A35M/A35F-50).

Before using the external IR receiver, be sure to arrange for your Kramer dealer to

insert the internal IR connection cable (P/N: 505-70434010-S) with the 3.5mm

connector that fits into the REMOTE IR opening on the rear panel. Connect the

external IR receiver to the REMOTE IR 3.5mm connector.
