Firmware Upgrade Installation
In some cases the DVS 406’s firmware may require replacement with an updated
version. There are three user-replaceable firmware chips: U41 — the main
microcontroller, U56, and U57. The numbers are printed on the circuit board. We
recommend that you send the unit to Extron for service and updates.
Changes to firmware must be performed by authorized service personnel
only. Some DVS 406 firmware updates must be performed at the
Extron factory.
Follow these steps to replace firmware in the DVS 406.
1. Disconnect the AC power cord from the DVS 406 to remove power from the
unit. Next, remove the input/output cables.
To prevent electric shock, always unplug the DVS 406 scaler from the
AC power source before opening the enclosure.
2. Remove the scaler from the rack or furniture.
3. Remove the cover of the scaler (the top half of the enclosure) by removing
the screws, then lifting the cover straight up.

Do not touch any switches or other electronic components inside the
scaler. Doing so could damage the scaler. Electrostatic discharge (ESD)
can damage IC chips even though you cannot feel it. You must be
electrically grounded before proceeding with firmware replacement. A
grounding wrist strap is recommended.
