*1. The display quality (e.g., contrast) will deteriorate at temperatures above 40°C. At low temperatures, the response 
       speed will be reduced due to the characteristics of liquid crystal. 
*2. The NT631/NT31/NT20 may not be able to be used in locations subject to long-term oil exposure.

*1. There are sometimes faulty in the touch panel, but this does not indicate an error as long as the number of bright or 
       dark pixels does not exceed the following limits. 
       4 total bright or dark defects maximum of the following size with no more than one per 20-mm square: 0.2 mm < 
       (short dia. + long dia.)/2 < 0.55 mm 
*2. This time is only a guide to the half-life of luminescence at room temperature and standard humidity. 
       The service life will be dramatically reduced in low-temperature environments. For example, the service life at 0°C or 
       less is approximately 10,000 hours (reference value).
