LCD UNIT MODIFICATION FOR DRIP-PROOF.
1.Model Name:
ER-A750
2.Description:
The LCD used in the ER-A750 may malfunction when liquid drips on the LCD and
enters into the circuit. Liquid may enter inside of LCD through the gap between the LCD
glass and the metal bezel holding the glass.
To prevent liquid from entering, the LCD will be overlaid with a transparent cover.
And also silicon rubber plates (LCD GUM A and LCD GUM B) will be added to seal the
gap between the LCD and the bezel at the right, left, and bottom. Please see attached
sheet how to modify the LCD.
3.Action:
For production:
The countermeasure has been implemented since Sept. 1998 production.
