Exit Setting Menu. See each setting section for
more details:
Changing Temperature Units from C to F (F1)
Press and hold «SET (left button) until you see
“F1” appear in bottom right corner of screen.
While showing F1 Symbol in bottom right
corner of the display, press »ADJ to switch
between ⁰C and ⁰F.
Temperature Offset Setting (F2)
With F2 Symbol showing in bottom right corner
of the display, press »ADJ (to increase) and
MODE (to decrease) to adjust the temperature
offset within the range of ±5⁰C ( ±9⁰F).
Note: This offset option only works for body
temperature mode.
Audio ON/OFF Setting (F3)
With F3 Symbol showing in bottom right corner
of the display, press »ADJ to turn on/off audio.
During the parameter setting mode, press the
trigger to directly exit from the setting mode.
Mode Switch
Press MODE button to switch between Human Body Temperature measurement
and Surface Temperature Measurement modes.
Press and hold MODE button to switch between display languages.

Temperature Measurement
Point to the measuring object at a range of 2-
3.15 in (5-8 cm) and press the trigger to begin
the measurement. The display screen will
display the temperature immediately within the
response time.
Surface temperature measurement mode:
Keeping the trigger pressed, the display will
indicate the object surface temperature live
with green backlight.
Body temperature measurement mode:
Press the trigger button once to take one
measurement. The number on the button left
corner shows the record number. The backlight
color indicates the different temperature range
as follows:
Green: Below 37.5⁰C (99.5⁰F)
Orange: 37.5⁰C-38⁰C (99.5-100.4⁰F)
Red: Above 38⁰C (100.4⁰F)
Data Record Management:

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 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.
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 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).
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 temperature of any surface.
2.) If the temperature looks correct, then go to menu (F2).
3.) Check the offset, the offset should be set to 0 ⁰C (0 ⁰F).
4.) If offset not set to 0 ⁰C (0 ⁰F), then set offset to 0 ⁰C (0 ⁰F).
5.) Switch back to body temperature mode and measure body temperature again, body
temperature should now be accurate.
