Abstract
A point to point communication apparatus, such as a digital radiopager (RP), having a non-volatile electrically programmable store which stores a radio identification code (RIC) or apparatus configuration information. The store can be programmed/reprogrammed by sending coded light signals to a light sensor. The coded programming/reprogramming light signals are supplied from an external source, such as a personal computer, and conform to a protocol which on being recognized causes a controller to permit access to the programmable store. The light sensor may also be used to sense the ambient light and control energization of a back light of a LCD panel.
