Basics Infrared Communication - 33
If these icons are not present or disabled, you will not be
able to make infrared connections from the iMac.
If you have used infrared communications with other Apple
products, you will notice a difference with iMac. The lens in
the rear of the iMac has been updated to support IrDA. The
new lens has about a 30 degree viewing angle. There is also
a minimum 3-foot distance for recognizing other Infrared
devices.
