Specific Absorption Rate (SAR) information:
This WPP-250 meets the government's requirements for exposure to radio waves. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons regardless of age or health. FCC RF Exposure Information and Statement the SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device types: WPP-250 has also been tested against this SAR limit. This device was tested for typical body-worn operations with the back of the WPP-250 kept 10mm from the body. To maintain compliance with FCC RF exposure requirements, use accessories that maintain an 10mm separation distance between the user's body and the back of the WPP-250. The use of belt clips, holsters and similar accessories should not contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not comply with FCC RF exposure requirements, and should be avoided.

Locations with much dust, particles, water or oil. Locations with slanted surfaces or strong vibration. Locations with direct sunlight. near heating/warming equipment, or temperature over 50 . Locations with temperatures of below -10 , a relative humidity of 80%or more, dew condensation caused by extreme temperature change. Location with electromagnetic noise or corrosive gas. Do not touch the dot line on the thermal head and driver IC with metal and sandpaper etc. There is a possibility for damage of those parts. Do not touch the dot line on the thermal head with your fingers. The contamination may reduce the printing quality. Do not use the printer if there is condensation occurs on the thermal head.
