3.2 Installing The Composite IF Aux Input Board
Observe Precaution for Handling Electrostatic Sensitive Devices.
Electrostatic Discharge (ESD) can damage the electronic components.
Therefore it is required to work in a static-save work station.
•
Install the optional board. See the internal layout for the correct location.
•
Fix the board with the 4 screws on the chassis profiles.
•

the newly delivered. The index of the software is indicated on the label stuck on the EPROM or GAL.
On the label you can find “/ XX”. This number indicates the software version.
Observe Precautions for Handling Electrostatic Sensitive Devices.
Electrostatic discharge (ESD) can damage the electronic components.
Therefore it is required to work in a static-safe work station.
For the location of the IC’s, use the Internal layout diagram.

EPROM
U65 with the one included in the kitbox. (only neccessary when the index of the
EPROM in the kitbox is higher than the one that is installed).
•
Replace
GAL
U69 with the one include in the kitbox. (only necessary when a GAL is included in
the kitbox and the index of the GAL in the kitbox is higher than the one that is installed).
