•After you release CONTRAST, the message “Contrast” remains on the display for a few moments, during which you can change the contrast setting further using [+] and [–] or by inputting a contrast value with the number keys.
The contrast can be set to a value from 0 to 99. The initial default setting is 50.

Initial reset
When batteries are set or an AC adapter is connected, the reset IC provides a low pulse to the CPU. When the power switch is pressed, the CPU receives a low pulse of POWER signal. The CPU first raises APO signal to +5 V to generate DVDD voltage, then raises RESET signal to +5 V. During this period the DSP and the key controller LSI initialize their internal circuits.

POWER SUPPLY CIRCUIT
The power supply circuit provides various voltages as shown below.
The voltage VDD (+5 V) is provided as long as batteries or AC adaptor is set. Other voltages are controlled by APO (Auto Power Off) signal from CPU.
