DISASSEMBLY / REASSEMBLY INSTRUCTIONSMCUK981201G8 Section 4 Issue 1Service Manual – 19 – Revision 0 ',6$66(0%/<5($66(0%/<,16758&7,216 *HQHUDOThis section provides disassembly and reassembly procedures for the main components of the GD70 system.These procedures MUST be performed by qualified service personnel, at an authorized service centre.The following warnings and precautions MUST be observed during ALL disassembly/reassembly operations:4.1.1 ESD Handling PrecautionsA working area where ESDs may be safely handled without undue risk of damage from electrostatic discharge, must beavailable. The area must be equipped as follows:Working Surfaces – All working surfaces must have a dissipative bench mat, SAFE for use with live equipment, connectedvia a 1M2 resistor (usually built into the lead) to a common ground point.Wrist Strap – A quick release skin contact device with a flexible cord, which has a built in safety resistor of between 5k2 and1M2 shall be used. The flexible cord must be attached to a dissipative earth point.Containers – All containers and storage must be of the conductive type.WARNINGThe equipment described in this manual contains polarised capacitors utilising liquid electrolyte. These devices are entirelysafe provided that neither a short-circuit nor a reverse polarity connection is made across the capacitor terminals. FAILURETO OBSERVE THIS WARNING COULD RESULT IN DAMAGE TO THE EQUIPMENT OR, AT WORST, POSSIBLEINJURY TO PERSONNEL RESULTING FROM ELECTRIC SHOCK OR THE AFFECTED CAPACITOR EXPLODING.EXTREME CARE MUST BE EXERCISED AT ALL TIMES WHEN HANDLING THESE DEVICES.CautionThe equipment described in this manual contains electrostatic sensitive devices (ESDs). Damage can occur to thesedevices if the appropriate handling procedure is not adhered to.
