4. Be sure that your KD-VPHD4X1 Switcher & Processor is set to “Normal” operating
mode.
To change operating Modes: Power must NOT be applied to your KD-VPHD4X1 Switcher &
Processor unit. The power supply MUST be disconnected (either from the back of your unit
or from the wall outlet) to have a complete power shutdown - reset.
Only select “Program” mode when you need to perform a Firmware Upgrade of your KD-
VPHD4X1 Switcher & Processor unit, as provided and instructed by Key Digital
® . Firmware
Upgrade instructions are provided later in this Operating Manual.
If the rear-panel Mode switch is set to “Program” mode and your KD-VPHD4X1 Switcher &
Processor unit is powered ON, or even if the power supply is connected and the unit is
turned OFF, the unit is expecting a firmware upgrade and will not operate properly. If you did
not intend to perform the firmware upgrade, turn your KD-VPHD4X1 Switcher & Processor
unit OFF. Then, you must physically disconnect power to your unit, set the rear-panel Mode
slide switch to “Normal” mode, physically reconnect power to the unit, and then turn the
power back ON to your unit for normal operation of your KD-VPHD4X1 Switcher & Processor.
5. Connect the external power supply to your KD-VPHD4X1 Switcher & Processor
unit.
Do not connect the external 6 Volt DC supply (provided) to the back of the Switcher &
Processor until all your Video and Audio connections to the KD-VPHD4X1 Switcher &
Processor are complete (as described in the prior step of this Operating Manual) and you
have set the Mode switch to “Normal” mode.
Once you have made all the A/V connections to your KD-VPHD4X1 Switcher & Processor and
the Mode is set to “Normal”, plug in the external 6 VDC @ 5 Amp Power Supply (provided with
your unit) to the jack on the back of the unit and connect the power cord into an appropriate-
ly rated wall outlet or power strip. You may now turn your KD-VPHD4X1 Switcher & Processor
unit ON using the front-panel pushbutton, the IR Remote Control, or RS-232.
