Circuit Descriptions

-6) Key Scan and Display Circuit

1) Key Scan and display operation.

The model uses a decorder IC which 4 inputs and 9

outputs. If the IC 9 decorder (TC4028BP) receivesd

signals from MICOM pins (3�6), an output signal per

2 miliseconds comes out from Q3, Q41, Q8, Q6, Q9,

Q7, Q0, Q2, and Q4 pin in sequence. This signal

enters to a driver IC input terminal of the CoolSelect

Zone

PCB and IC5 (TD 62783AP), then approximate

11V peaks will generate from an output terminal as

shown on the next page.
