              Warnings on Usage 
For your safety and proper use of the SK-1120, be sure to observe the following: 
 
- Do not use the SK-1120 as clinical thermometers. 
- Never disassemble or alter the SK-1120, which may cause malfunctions. 
- Do not drop, vibrate or apply shock to the SK-1120. They are precision instruments. 
- Make sure the SK-1120 operate under an ambient temperature of 0 to 50°C and a relative 

humidity of not more than 80%. Otherwise, malfunctions may occur. 

- Avoid using the SK-1120 in a place exposed to direct sunlight or near heating equipment. Doing so 

may result in measurement errors or deformation/discoloring of the casing. 

- Do not use the SK-1120 in an environment where electrical noise is generated. Doing so may 

result in unstable display or lower accuracy. 

- Never use the SK-1120 out of the measurement range, as this may cause malfunctions. 
- Never wet or use the SK-1120 underwater. They are not of waterproof construction. 
- When used outdoors, keep the SK-1120 out of rain or water splashes. If it becomes wet, the unit 

may fail. 

- If the unit is not to be used for a long time, always remove the batteries which may otherwise leak 

fluid and cause failure. 

- Do not dispose of the used batteries in a fire. 
- Keep the batteries out of the reach of children. If a battery is swallowed accidentally, consult a 

doctor immediately. 

- Dispose of used batteries according to your local waste disposal regulations for environmental 

conservation. 

- Do not wash or wipe the SK-1120 with alcohol, thinner or other solvents. If the unit becomes dirty, 

wipe it with a tightly-wrung towel or the like that has been dipped in warm water with a neutral 
detergent. 

- Do not alter, pull forcibly, bend or bind the sensor probe(s), as doing so may break the probe. Also, 

do not place heavy objects on the cord or heat it, as doing so damage the cord. 

-To prevent injury, be careful of the sharp tip of the sensor especially when cleaning the sensor after 

taking measurements, and take care not to drop the sensor. 

- Ask either your local Sato sales representative or our Service Network for repair and calibration 

of your SK-1120.
