if 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-4HN 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.

4.1 Acquiring an EDID

To acquire an EDID, press the EDID SETUP button as follows:

1. The first press of the EDID SETUP button displays the present EDID status

similar to that shown in the next step.

2. The second press of EDID SETUP enters the read mode and each

additional press cycles through the source options:

OUT 1 -> OUT 2 -> OUT 3 -> OUT 4 -> all LEDS flash slowly for auto-mix ->

all LEDs flash quickly for a default EDID.

3. When the desired EDID source is reached, release the EDID SETUP button.

The VM-4HN reads the EDID for a few seconds. When finished, all LEDS

return to display the present output connection status.

If an unconnected output is chosen or the EDID cannot be read, the VM-4HN loads the

default EDID.
