Precautions
Attentions
• Use of this thermometer is not intended as a substitute for consultation with your physician.
• Never use the thermometer for purposes other than those for which it has intended.
• Never immerse the thermometer into water or other liquids.
• Never insert a sharp object into the scanner or any other opened surface on the thermometer.
• Do not scratch the probe membrane, if not the thermometer shall lose the efficacy.
• Do not expose the thermometer to sunlight.
• Do not expose this thermometer to electric shock.
• Do not use near strongelectromagnetic fields, i.e. Keep it away from any radio systems and mobile
phones.
• Do not modify this device without authorization of the manufacturer.
• Do not impact the thermometer, otherwise it may affect the accuracy of the measurement.
• Do not let children take their temperatures unattended.
• This device must always be kept in a clean, dry area.
• This device includes small parts, don’t inhale or swallow it.
• Follow local ordinances and recycling instructions regarding disposal or recycling of the device and
device components, including batteries.
• The thermometer needs to acclimate to the temperature of the room in which the measurement will
be taken for 10 minutes.
• This equipment complies with IEC 60601-1-2:2014 for electromagnetic compatibility for medical
electrical equipment and/or systems. However, because of the proliferation of radio-frequency
transmitting equipment and other sources of electrical noise in healthcare and other environments, it
is possible that high levels of such interference due to close proximity or strength of a source might
disrupt the performance of this device.
• The material that contacts with the user’s skin contains ABS plastic enclosure and passes the
ISO10993-5 Tests for invitro cytotoxicity and ISO10993-10 Tests for irritation and delayed-type
hypersensitivity.
• Portable RF communications equipment (including peripherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12 inches) to any part of the device, including
cables specified by the manufacturer. Otherwise, degradation of the performance of this equipment
could result.
• The essential performance of the device: display the body temperature accurately. If the Essential
Performance is lost or degraded due to EM disturbances, the reading may inaccurate. Please do not
reference.

Battery Installation
To install or replace the batteries, follow the steps:
1. Slide the battery cover off.
2. Install two AAA batteries into the battery compartment. Make sure to align the positive and negative
ends properly as indicated inside the compartment.
3. Replace the battery cover.
Notes:
• Please remove the batteries from the product if it is not required for extended periodsof time in order
to avoid leakage.
• To protect the environment, dispose of empty batteries at appropriate collection sites according to
national or local regulations.
Select Age Range
1. Power the thermometer on with a short press on power button. Each time you power it on, the
device will default to age range selecting mode.

2. Press and release power button to cycle through three age ranges. You may select:
36+months, 0-3 months, 3-36 months, the device will display as below:
Note:
The default age range is “36+months”.
Measure Forehead Temperature
Prepare for measurement:
Follow these guidelines to take an accurate and reliable measurement.
1. The individuals being measured should be indoors for 30 minutes before taking a measurement.
2. Individuals should not drink, eat, or be physically active before/while taking the measurement.
3. Ensure that the individual’s forehead is prepared for measurement.
• Remove any sweat prior to measurement.
• Remove hats and wait 10 minutes before taking the measurement.
• Remove dirt or hair from the forehead area and wait 10 minutes after cleaning before taking the
measurement.
• Avoid any cooling or warming cloths on the forehead for at least 30 minutes prior to measurement.
4. Keep the measurement sensor and lens clean. Avoid directly touching the sensor.
Take a measurement:
1. Select an age range (refer to selection “Select Age Range”);
2. Press scan button to enter “measuring” operation sequence;
3. Short press power button to toggle between human temperature mode (face symbol ) and object
temperature mode (house symbol ).
4. Position the thermometer on or up to 0.4 inch (1cm) away from center of
the forehead, between eyebrows. Do not directly contact with the
forehead.
Notes:
• Always take the temperature exactly as directed. Temperature results
may vary if positioned in wrong locations.
• Do not take temperature measurement over scar tissue, open sores, or abrasions.
• Hold the device and forehead steady.
5. Press scan button again. Read the temperature from the screen.
If the individual temperature being measured is normal, one “beep” will sound and smile face icon
will appear on the screen (see Fig. 1).
Fig. 1
If the individual temperature being measured is in the fever range, four “beeps” will be heard and upset
face icon will appear on the screen (see Fig. 2). If so, please take three temperatures at same location
and take the highest one as the reading (Wait at least 5 seconds between consecutive readings).

Notes:
• The measurements can be recorded and transmitted via Bluetooth (Bluetooth transmission is optional).
The Bluetooth symbol will be lighted once the Bluetooth starts up, otherwise it will keep flashed.
• The battery symbol indicates the remaining battery capacity. When voltage of the battery is low,
the display flashes the low battery warningsymbol . The device can still work until the battery life has
0% left.
