Claim Text:
1. A cellular telephone comprising: a first portion including a user interface and a low radiation level communications circuit; and a second portion including a low radiation level communications circuit and a cellular communications circuit; wherein the low radiation level communication circuits of the first and second portions are operative to communicate with each other both when the first and second portions are coupled and when they are separated; wherein the first and second portions are removably coupled to each other so as to allow a user of the cellular telephone to communicate over a cellular network by communicating through the first portion to the second portion while the second portion is separated from the first portion; wherein a first communication power level, between the first portion and the second portion, is lower than a second communication power level, between the second portion and the cellular network, to reduce radiation exposure to the user, wherein the second portion is operable to sense that the second portion is separated from the first portion, wherein the second portion is operable to automatically increase the second communication power level to a third communication power level when the second portion senses that the second portion is separated from the first portion; wherein the first communication power level of the first portion is provided by a first power supply that includes a battery; and wherein the second communication power level of the second portion is provided by a second power supply.
