摘要：
A medical device includes a display area that has a thin panel having a substantially flat front surface portion, a translucent layer on a back surface of the thin panel, a layer of text or graphics on a back surface of the translucent layer, and arranged so that the text or graphics is not visible to a user on the front side when light is not provided from inside the device housing, a switch to allow a user to select a first mode or a second mode for the device, and circuitry arranged to energize one or more light sources to provide light from behind the thin panel when the device is in the first mode, and to thereby make visible the text or graphics when the device is in the first mode.
