The Wire-Lists

SM transmitters might go through hell on the job --  but they don’t have to look like it.  Battery doors and the 5-pin jacks are particularly susceptible to wear and tear. These tips can help:

Battery Doors

If the battery door and mating surface on your SM series transmitter look like this and are starting to become difficult to open, don’t scrub them with an abrasive!  We’ve seen a few units that were damaged by steel wool, sandpaper and other materials. Multiple problems can be created as a result, such as getting particulate (tiny pieces that break off) into the unit, damaging the battery contacts on the door, and removing the conductive coating from this area and even the entire housing. 

To clean, we recommend Wright’s Silver Cream (available in Walmart and Home Depot; under $10 for a small container that will last you a year or more) to clean the door and housing.
