COMMANDS & DATA
• Transferring display data/displaying on LCD: command (1 Byte) + data (256 Bytes)
• Others: command (1 Byte) + data (1 Byte)
• Commands can be accepted only when all bits coincide; otherwise, they are not acknowledged
• Additional commands will not be received until the communication of commands (1 Byte) and data (256 or 1 Byte) is completed
• There is no time limit from the beginning to end of data receipt
• Commands may be executed consecutively (no need to wait between commands)
• Irregular commands or data are not recognized
• Initial status at power activation: LCD display off, LED off (brightness 1/20, color off)

PRECAUTIONS FOR HANDLING & STORAGE OF LCD DEVICES
ATTENTION
ELECTROSTATIC
SENSITIVE DEVICES
Handling
1. The IS Series devices are electrostatic sensitive.
2. Limit operating force to keytop to 100.0N maximum, as excessive pressure may damage the LCD device.
3. The IS series devices are not process sealed.
4. If the LCD is accidentally broken, avoid contact with the liquid and wash off any liquid spills to the skin or
clothing.
5. Clean cap surface with dry cloth. If further cleaning is needed, wipe with dampened cloth using neutral
cleanser and dry with clean cloth. Do not use organic solvent.
6. Recommended soldering time and temperature limits: 5 seconds maximum @ 270°C maximum
7. Do not exceed 60°C at the LCD level.
Storage
1. Store in original container and away from direct sunlight.
2. Keep away from static electricity.
3. Avoid extreme temperatures, high humidity, gaseous substances, and all forms of chemical contamination.
