VM-4HN - Getting Started
2 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 http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check
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.
