INSTALLATION GUIDE FOR THE PR4000 DIGITAL MODEM BOARD

The purpose of this guide is to describe the correct procedure for the installation of the digital modem board in the PR4000. The modems are extremely sensitive to static electricity, (more so than RAM), and should be handled with caution. The body carries static electricity and if the person installing the board is not correctly grounded, the modem board could suffer irreversible damage. Please follow the instructions outlined below carefully to avoid damaging the board.

Step One:

Unplug the PR4000 from the power source and remove the power cord. Remove all cables connecting the PR4000 to other devices.

Step Two:

Carry the PR4000 to a workbench or table with an anti-static surface and wrist-strap. If a workbench of this type is not available, use the wrist strap sent with the modems. The directions should be followed carefully. Please note that the wrist-strap should not be connected to the PR4000 because it is no longer plugged in an thus no longer connected to ground.

Step Three:

Remove the four top screws and the eight screws on the bottom edges of the PR4000, as shown in the figure.
