5. Glass is used in the panel, so be careful not to drop it or let it strik\
e a hard object, which 
could cause breakage or cracks. 
 
 
6.  CMOS-LSI circuits are used in the module, so guard against damage from electrostatic 
discharge. Be sure to wear a wrist or ankle grounding device when handli\
ng the module.
