******WARNING !******
ELECTRO-STATIC DISCHARGE
Before installing or touching any exposed printed circuit boards, chips, PROMs, electronic unit parts, etc., make certain that you are properly grounded. This is extremely important, as most internal electronic components are highly susceptible to damage from Electro-Static Discharge. Service Technicians should ground themselves by wearing a wrist strap that is connected to an electrical ground. If you do not have wrist strap, you can ground yourself and dissipate any Electro-static build up by doing the following: 1. Connect the unit�s power cord between the unit and a three pronged (grounded) electrical outlet. 2. Turn the main AC power-switch to the OFF position on the unit. 3. Touch, and maintain continuous contact with, an exposed metal surface of the unit, such as the inside of the unpainted chassis or a grounded stainless steel screw, while handling any internal components, IC�s, or printed circuit boards while performing modifications or repairs.
