Access Tool Modification
If you wish to modify the access card tool, order kit 076-1213. The kit contains an access card and 
a piece of EMI gasket that can be cut and added to the top of the card. The additional thickness 
on the card will improve the contact with each bezel latch.Remove the tape on the gasket to expose the sticky side of the gasket. Attach the sticky side 
1.  
of the EMI gasket to the top of the access card. 
Cut the EMI gasket to the edge of the access card. 
2.

EMI Shielding
The iMac enclosure is wrapped in EMI shielding that is easily torn and damaged. To maintain a 
properly shielded unit, you must repair all accidental tears and cracks to the shielding by 
covering them with EMI tape.  Order EMI tape, part number 922-4786 (a long, thin strip) or 
922-5026 (short, wide strips). 
 
Cover nicks, such as the those shown below, with EMI tape. Pay particular attention to the EMI 
shielding inside the rear housing, shown below. The EMI shield is easily damaged when replacing 
modules.

Lower EMI Shield
EMI tape covers the top and sides of the display panel, and the lower EMI shield covers the logic 
board along the bottom of the unit. The EMI tape and lower EMI shield are easily damaged when 
removed, and removal is necessary in order to access most components within the unit. 
Should the EMI tape that seals the display, or the EMI shield covering the bottom of the 
enclosure (see photo below) accidentally tear, use EMI tape (922-4786 or 922-5026) to repair and 
completely seal the unit. 
When properly repaired, all edges shown below will be wrapped by EMI tape, and the tape 
securely adhered to all edges. Use a black stick to flatten the EMI tape tightly and rub out air 
pockets and wrinkles.
