Abstract

The wireless PDT (2) of the present invention employs a 'display-on bottom' design which places the unit perfectly centered in the hand of the operator, allowing for the best possible viewing as well as providing comfortable single-handed operation. The high­-resolution LCD (8) display allows the PDT (2) to show sharp, clear bitmap images while supporting all Windows-recognized font types and sizes. With the auto back-lit feature, the brightness adjusts automatically making the screen easy to read in all light conditions. The PDT (2) is designed for support within the download/charger cradle of a base station (3)which interfaces with a host system using either USB or RS232 interface. Two standard 'AA' or rechargeable Li-Ion batteries provide more than 100 hours of operation. In addition, the PDT(2) comes standard with 2MB or RAM providing enough memory to store over 100,000 records.
