C. Applications

1. Target User: Infants, children, and adults.
2. Measuring Point: forehead.
3. Applications field: Hospital, clinic, school, institution, and families.

Using the Unit and Troubleshooting:

A. Preparation
Function setting
Hold the SET button 2 seconds enter setting mode. LCD display F1 icon，press + button to select function: Temperature offset → Fever alarm→ Buzzer → Exit.
Mode switch
Press the SET button to switch calibration mode or body/surface temperature mode.

Taking a Reading
Press the START button.
The measurement is complete in 1 second with a long beep.
Move the unit away from the forehead and check the measurement result.
The display lights up for 5 seconds.
Notes:
If the result is lower than 37.5°C, appears green blacklight on the display.
If the result is higher than 38°C, appears red black light on the display.
If the result is between 37.5°C ~ 38°C, appears orange black light on the display.

Using the Memory Function
This unit automatically stores the last 25 measurement results.
Press the + or – button to check the record. If the memory is full, the unit will delete the oldest reading.

B. Caution

1.  Always make sure the probe is clean and undamaged, and the forehead is clean with no sweat, cosmetics, scars, etc.

2. Prior to measurement, ensure that the patient has not taken a bath or exercised within the last 30 minutes, and has remained in a stable environment for at least 5 minutes.

3. It is recommended to perform measurement three times. If the three measurements are different, select the highest temperature.

4.  Hold the unit with the probe 1 to 3 cm away from the center of the forehead.

5. Holding the unit too long in the hand may cause a higher ambient temperature reading of the probe.
   This could make the body temperature measurement lower than usual.

6. Keep still during the measurement.

C.Troubleshooting and Maintenance
The Icons and Error Messages
The display appears “HI”
Forehead measurement mode: The temperature taken is higher than +42.9°C.
Use the unit within its measurable range.
The display appears “Lo”
Forehead measurement mode: The temperature taken is lower than +34°C (93.2°F).
Use the unit within its measurable range.

Questions and Answers

1. The temperature indicated is rather high.
   The unit has been stored in a cold room. When the unit has been stored in a cold room, the measured temperature may be rather high if you measure the temperature shortly after bringing the unit to a room that is at normal temperature. Measure temperature after leaving the unit for 30 minutes in the room where it will be used. It is advisable to store the unit in the room where you are going to mean temperature. The probe has been exposed to direct sunlight. Measurement was taken shortly after the subject cried. Crying can increase facial temperature.

2.  The temperature indicated is rather low. The body is sweaty. Do not use the unit when wet after swimming, bathing, or sweating after physical exercise, as skin temperature may have fallen. Wipe away moisture and allow 30 minutes for the body to acclimatize to room temperature before measuring. The probe is dirty. Measurement was taken in surface temperature mode. Use forehead measurement mode. Measurement was taken shortly after the subject was outdoors in cold weather. Wait until the forehead has warmed up. Measurement was taken at a location other than the forehead sure to measure exactly at the forehead, not surrounding areas such as the hairline.

3. There are variances in the measurement values.
   – Measurements were not taken at the same location.
   – The probe lens is dirty.

4. The temperature measured on this unit is not equivalent to oral temperature. – Forehead thermometers may not always calculate the exact oral-equivalent value. It is recommended to take regular measurements on subjects such as family members, etc., who are in good physical condition, to know their normal temperature.

About Body Temperature
Body temperature refers to the stable temperature of the inner body (also known as the core body temperature). While temperature measurements at the armpit or mouth provide surface temperature values, holding the thermometer steadily at the measurement point for approx. 10 minutes provides a temperature measurement more closely representing that of core body temperature. Since forehead temperature measurement involves no bodily support of the thermometer, the resulting measured temperature is typically lower than that of the armpit or mouth. However, since the forehead has blood vessels that are much less prone to vascular constriction (a natural function of body temperature adjustment), it is supposedly a better measurement area for determining core body temperature, even in a lower temperature environment. By contrast, the temperature measured at the arm or leg, for example, is not a suitable gauge of core body temperature, since such body areas are more subject to vascular constriction. (Note that temperature measured at the forehead may still be influenced by other conditions, such as sweating, or wind from an air conditioner, etc. It is therefore advised to perform the measurement in as stable an environment as possible.) When measuring the temperature of an infant, note that infant body temperature is generally higher than adult body temperature and easily affected by external factors. For example, body temperature tends to increase after nursing or crying. Therefore, it is recommended to take measurements with the infant in a calm and normal condition.
Temperature differences between body temperature and forehead temperature

This unit measures the temperature at the surface of the forehead by sensing infrared emission of the skin at the measured point and then calculates the oral-equivalent value using a unique algorithm (forehead measurement mode) based on actual body temperature survey data.

Maintenance, Cleaning, and Disinfecting Instructions

A. Maintenance
Check the unit if it is dropped.
When the probe becomes dirty, wipe it lightly with a soft dry cloth or a cotton swab.
Do not wipe the probe lens with tissue paper or a paper towel.
Clean the probe carefully to avoid damaging it.
– Use a 70% alcohol swab or soft cotton moistened with 70% alcohol to clean the probe.
– Allow the probe to fully dry for at least 1 minute.
Do not store the unit in the following types of places. Doing so may damage the unit.
– Wet locations.
– Locations with high heat and humidity or those that are exposed to direct sunlight.
Areas close to heating equipment, dusty locations, or environments where there are high salt concentrations in the air.
– Locations where the unit will be subjected to leaning over, falling, shock, or vibration.
– Pharmaceutical storage areas or locations where corrosive gases are present.
B. Cleaning and Disinfecting
– Never submerge the thermometer in water or any other liquid.
– Never use abrasive cleaning agents, thinners, or benzene for cleaning, and never immerse the unit in water or other cleaning liquids.
– Never insert a sharp object into the scanner area or any other open surface on the thermometer.

– Do not use unapproved cleaning or disinfection agents. The use of these agents may cause damage to components.
– Do not use chemicals other than isopropyl or ethyl alcohol on the probe.
Cleaning & Disinfecting the Thermometer
It is recommended to disinfect the unit prior to first use. The unit is compatible with most common disinfection chemicals products. It can be subject to the following exposures with no degradation in
safety or e-cacy.
– 1/100 1% Bleach
– Alcohol prep pads
Disinfection should be carried out as per standard facility procedures. No special precautions or procedures are required for the unit.
