In some examples, a portable data terminal (PDT) is configured to vibrate when it is installed in a base (e.g., of a docking station), which may help improve the electrical contact between the PDT and the base. For example, when the PDT is installed in a base and subsequently vibrated, the electrical contacts of the PDT may vibrate against opposing electrical contacts in the base, which may help remove contaminants, such as dirt and other debris, from between the electrical contacts of the PDT and the base. |
