It is recommended that all SS pins be connected to a controller pin
instead of ground. A clock glitch during power up could cause the
communication to fall out of sync. Toggling the SS line resets the
communication.

• 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)

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:
Do not exceed 60°C at the LCD level.
Wave Soldering: see Profile B in Supplement section.
Manual Soldering for Switch: see Profile A in Supplement section.
Manual Soldering for Display: see Profile B in Supplement section.
7. Excessive images may result after the same image is emitted continuously for an extended period of time.
8. The highest backlight brightness level should not be used for temperatures above +35°C.
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.
