Operation Manual
5 Spray compressed air in the connector area by pointing the tube/nozzle about ½ inch away from the surface.
6 Remove any lint left by the cotton-tipped applicator.
7 If grease and other dirt can be found on other areas of the cradle, use a lint-free cloth and alcohol to remove.
8 Allow at least 10 to 30 minutes (depending on ambient temperature and humidity) for the alcohol to air dry before
