Autostar Keypad Contact Repair
By K.C. Kile, Sr.
At some point in the life of your Autostar handset, it’s response to your input will most likely become less than desired. This may happen at the beginning when the unit is new, or appear after several years of use. The first instinct is to open the handset and clean the pads and contacts with alcohol. This is a definite NO-NO. Although your cotton swab will become black with material that you attribute to the problem, performance of the handset will be further degraded, as you have just removed the substance apparently used to insure good contact. I have found the most effective repair to be obtained from the Chemtronics CW2605 Rubber Keypad Repair Kit shown in Figure 1. This kit can generally be purchased from major electronic parts supply stores for under $15 and is of sufficient quantity to do approximately 20 handsets. The down side is that it only has a 72 hour pot life after mixing. DO NOT attempt partial product mixing to conserve!
