-
- Article Created: 17 November 1993

- TOPIC ---------------------------------------------------------
-
- I'm having severe (EMF) Extremely Low Level Magnetic Field Interference
- problems with Apple 14" AV Color Displays connected to Centris 660AV,
- Centris 650 and Macintosh LCIII computers.
-
- Symptom: continuous vertical undulating interference on the monitor.
-
- DISCUSSION ------------------------------------------------------
-
- Apple monitors are no more susceptible to EMF than any other monitor on the
- market today. All monitors will demonstrate symptoms associated with EMF
- if the source is of sufficient strength.
-
- Here are a few possible solutions:
-
- 1. Check the AC power line for noise. Apple has seen instances where
- noisey power lines induced the exact symptom you are describing.
-
- 2. Locate the source of the EMF and then shield the wall between the
- source and the equipment.
-
- 3. Rotate the position of the monitors slightly, this may decrease the
- effect of the EMF field.
-
- 4. Shield the monitors with special five sided mu metal shields. However,
- please note that this is a very expensive solution.
