"We were able to reduce the overall size through the design of advanced linear and digital ICs," says Weisshappel. Using the Micro TAG is as easy as any communicator: Flip the top open, speak to answer a call. You make calls by dialing the number or by speed dialing any of the 120 user-programmable numbers stored in its memory. An LED displays the name and number of the person you've selected. There's also a call timer to show how long you've been speaking, an electronic lock to prevent unauthorized calls, and a "call" message light, which I don't understand. According to Motorola, the light comes on to show that a call has come in "while the user was away." Away from what? His shirt?
