PRECAUTIONS FOR HANDLING & STORAGE
Handling
1. 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 itself may become damaged.
2. The IS Series devices are electrostatic sensitive.
3. Limit operating force to keytop to 100.0N maximum, as excessive pressure may damage LCD device.
4. Recommended soldering time and temperature limits are 5 seconds maximum @ 270°C maximum.
5. Do not exceed 60°C at the LCD level.
6. The IS series devices are not process sealed.
7. If the LCD is accidentally broken, avoid contact with the liquid and wash off any liquid spills to the skin or clothing.
8. 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.
Storage
1. Store away from direct sunlight.
2. Keep away from static electricity.
3. Avoid extreme temperatures, high humidity, gaseous substances, and all forms of chemical contamination.
