Outline

Handset consists of the following ICs as shown in

Block Diagram (Handset)

(P.18).

• DECT BBIC (

ase

and IC): IC5

- All data signals (forming/analyzing ACK or CMD signal)
- All interfaces (ex: Key, Detector Circuit, Charge, EEPROM, LCD)

• EEPROM: IC3

- Setting data is stored. (e.g. ID, user setting)
