Actually, Don, A breath from your mouth is really good advice. It would contain a lot of water vapor which will help remove the electrostatic charge on the plastic - at least in the short run. The canned air and the nylon brush will both likely exacerbate it.

Dan, The original question has already 'morphed' to one of general use of air or products for cleaning circuit boards. Let us think about one of the reasons for that statement in the manual. The VFO A encoder has a plastic plate under it. We all know that plastic can often build a static charge which will attract dust and other small particles. If the area under where the plastic will be mounted has lint or dust, it can show up badly when the plastic is attached.. That could include gently wiping the area with a slightly dampened lint-free soft cloth, or even using a cloth one would normally use to clean eyeglasses. The use of a dry brush may not work if used on the plastic because some type brushes may actually increase the static charge and make matters worse (but then, the manual states to clean the area *under* where the plastic will mount and does not refer to the plastic itself). Use whatever works and is sufficiently kind so that no damage occurs. A quick 'breath of air' from your mouth may be all that is required. 73, Don W3FPR Dan Nixon wrote: > I'm an old ham who has built a lot of kits over the years.
