9. CEO can only sustain leakage current in the battery backup mode.
10. All AC and DC electrical characteristics are valid for the full temperature range. For commercial products, this range is 0
to +70°C. For industrial products (N), this range is -40°C to +85°C.
11. DS1210 is recognized by Underwriters Laboratories (UL) under file E99151.
