Precautions before first use
- Install batteries before use
- Before first use, warm up the device for about 10 minutes before installing the battery.
- When using it for body temperature measurement point thermometer at the forehead. This is a non-contact thermometer and the suggested measuring distance to the forehead is 5cm (2in). Press the trigger once to take one temperature measurement. Tip: temperature can also be measured at an earlobe.
- When measuring body temperature, please make sure there are no obstacles between the IR sensor and forehead skin, e.g., move hair or sweat if obstructing measurement.
Warnings
- The glass protector in front of the IR sensor is a critical but very fragile element of the device.
- Use cotton and 70% rubbing alcohol for cleaning.
- Please only use qualified battery. Do not charge batteries that are not rechargeable.
- Do not use the thermometer under the sun or under water.
Maintenance
- Please follow the instruction manual for troubleshooting. If the issue is not listed in the manual, please contact our customer support.
- Warning sign “HI”
- When using the thermometer for measuring body temperature, the “HI” warning sign may come on. The warning sign indicates the temperature measured exceeds the maximum allowed threshold 43⁰C (109.4⁰F).
- Warning sign “LO”
- When using the thermometer for measuring body temperature, the “LO” warning sign may come one. The warning sign indicates the temperature measured exceeds the minimum allowed threshold 32⁰C (90⁰F).
