Precautions before first use

1. Install batteries before use

2. Before first use, warm up the device for about 10 minutes before installing the battery.

3. When using it for body temperature measurement point a thermometer at the forehead. This is a non-contact thermometer and the suggested measuring distance to the forehead is 2” (5 cm).
   Press the trigger once to take one temperature measurement. Tip: temperature can also be measured at an earlobe.

4. 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 a 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 of 108.5⁰F (42.5⁰C).

• 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 of 89.6⁰F (32.0⁰C).

Troubleshooting

• When using the thermometer in body temperature mode, if a “HI” or “Lo” warning sign is displayed and it is suspected that the temperature is incorrect please follow these steps:
  1.) Switch to surface temperature mode, measure the temperature of any surface.
  2.) If the temperature looks correct, then go to the menu (F2).
  3.) Check the offset, the offset should be set to 0⁰C (0⁰F).
  4.) If offset is not set to 0⁰C (0⁰F), then set offset to 0⁰C (0⁰F).
  5.) Switch back to body temperature mode and measure body temperature again, body temperature should now be accurate.
