Replacing the Alpha-Numeric Keyboard Assembly

The Alpha-Numeric Keyboard Assembly is not a FRU, but both the language specific keyboard, called

the A/N keyboard, and the A/N Keyboard Enclosure are FRUs. These two parts together equals one

Alpha-Numeric Keyboard Assembly.

Preparations

When preparing for the replacement, you must perform the following steps:

DO NOT TOUCH ANY BOARDS WITH INTEGRATED CIRCUITS PRIOR TO TAKING THE

NECESSARY ESD PRECAUTIONS.

1. ALWAYS CONNECT YOURSELF, VIA AN ARM-WRIST STRAP, TO THE ADVISED

ESD CONNECTION POINT LOCATED ON THE REAR OF THE SCANNER (NEAR THE

POWER CONNECTOR).

2. FOLLOW GENERAL GUIDELINES FOR HANDLING OF ELECTROSTATIC SENSITIVE

ENERGY CONTROL AND POWER LOCKOUT FOR VIVID E9.

WHEN SERVICING PARTS OF THE SYSTEM WHERE THERE IS EXPOSURE TO

VOLTAGE GREATER THAN 30 VOLTS:

1. FOLLOW LOCK OUT/TAG OUT PROCEDURES.

2. TURN OFF THE BREAKER.

3. UNPLUG THE VIVID E9.

4. MAINTAIN CONTROL OF THE POWER PLUG.

5. WAIT FOR AT LEAST 20 SECONDS FOR CAPACITORS TO DISCHARGE, AS THERE ARE NO TEST POINTS TO

VERIFY ISOLATION. THE AMBER LIGHT ON THE OP PANEL ON/OFF BUTTON WILL TURN OFF.

BEWARE THAT THE MAIN POWER SUPPLY AND BACK END PROCESSOR MAY BE ENERGIZED EVEN IF THE POWER

IS TURNED OFF WHEN THE CORD IS STILL PLUGGED INTO THE AC OUTLET.

1.) Power down the VIVID E9.

2.) Disconnect the Mains Power Cable from the wall outlet.
