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 70°C at the LCD level. Wave Soldering: see Profile B in the Supplement section. Manual Soldering: see Profile B in the Supplement section. 7. Recommendation for backlight color uniformity: Use constant current driver. For current limiting resistor method, the power source should be at least twice the backlight LED forward voltage. 8. The VLC voltage should not be applied before logic voltage. If VLC voltage is present before logic voltage, it may cause the driver logic to freeze and damage the LCD, and the driver logic may become damaged. 9. Backlight Forward Current should not exceed the derated Absolute Maximum Forward Current based on the temperature. 10. Excessive images may result after the same image is emitted continuously for an extended period of time. 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. www.nkk.com 5
