Forehead temperature| The thermometer has been designed for home use.
It’s not meant to replace a visit to the doctor. Please also remember to
compare the measurement result to your regular body temperature. Please
consult with doctor if you have health concerns.
Please see the “Use of the thermometer” section to learn how to measure the
body temperature.
Surface temperature| The surface mode shows the actual and unadjusted
surface temperature which is different from the body temperature. It can help
you monitor if the object temperature is suitable for the baby or patient, for
example the baby’s milk.
Please see the “Use of the thermometer” section to learn how to measure the
object temperature.
Fever indication| If the thermometer detects a temperature ≧37.5°C (or
99.5°F) under forehead mode, three short beep sound will follow one long beep
sound to warn the user for potential fever.
Memory locations| There are total 25 sets of measurement condition for
body temperature.
When power on, press the “ON/MEM” button to see the temperature records with
icon.
°C / °F switch| In “ Power Off ” mode, press and hold the “START”
button, then press the “ON/MEM” button for 3 seconds, icon “°C” will be
switched to icon “°F”. You can also use the same process to change the LCD
display from °F to °C.
NOTE : Memory clear and Celsius/Fahrenheit switch are together. When you
switch Celsius and Fahrenheit, the Memory will be cleared.
Mute mode| The device setting with buzzer is on, you can set buzzer
on/off under Mute mode.
When power on, press and hold the “ON/MEM” button for 3 seconds. The icon
will flash on the LCD screen and then release the “ON/MEM” button to set MUTE.
Thus you will not hear beep sounds. You can also use the same process to turn
off the Mute function.
NOTE: If keep pressing “ON/MEN” button for 5 seconds after icon flashing, the device will be power off WITHOUT setting Mute.
Use of the thermometer
Note: If there is any temperature difference between the places where the device is stored and where you are going to measure, subject and the device should stay in the same room for at least 15 minutes before measurement.
-
Always make sure the probe lens is clean without any damage and the forehead is clean.
Warning: Choking from swallowing small parts and batteries by children or pets is possible, please keep small parts and batteries at places where children and pets can’t reach. -
Power on:
Press the “ON/MEM” button (see figure 1).
-
Measuring body temperature on the forehead:
Press the “ON/MEM” button to power on the device. Forehead mode is the default mode. You can see the icon on the screen and hear two beep sounds (see figure 1). In this mode, you can hold the thermometer within 4 cm from the central forehead (Fig. 2) and press the “START” button to get the forehead measurement. The time consuming for measurement might be 1 second. After each forehead measurement, wait icon stop flashing to be ready for next measurement.
Points for attention:- Forehead temperature is displayed in oral mode. This mode converts the forehead temperature to display its “oral-equivalent” value.
- Before the measurement, the subject should stay in a stable environment for 5 minutes and avoid exercise, bath for 30mins.
- Remember to keep the forehead area clean and away from sweat, cosmetics and scar while taking temperature.
- The “Clinical Bias” is -1.4~-1.7°C.
- The “Limits of Agreement” is 0.98.
- The “Repeatability” is 0.20°C.
-
Measuring surface temperature:
-
After power on, press and hold the “ON/MEM” button, and press the “START” button one time for “Infrared thermometer” mode to see icon on your LCD display. In this mode, you can get the target surface temperature.
-
When you press the “START” button, you will get the real time temperature immediately. If you press and hold the “START” button, the reading of measurement will be continuously updated.
-
Applications include temperature measurements for water, milk, cloth, skin or other objects.
Note: This mode shows the actual and unadjusted surface temperature which is different from the body temperature. -
Power off:
-
Device will automatically shut off if left idle for more than 1 minute to extend battery life.
-
Manually power off the device by pressing the “ON/MEM” button.
Important Notes
Important Notes
Cleaning And Storage
| Please make sure the probe is clean to ensure an accurate reading.
The probe lens is the most delicate part of the thermometer. Use with care when cleaning the probe lens to avoid damage.
a. Use alcohol swabs or cotton swabs moistened with 70%~75% alcohol to clean the probe lens.
b. Allow the probe to fully dry for at least 1 minute.
c. Keep the unit dry and away from any liquids and direct sunlight.
d. Storage temperature range: It should be stored at room temperature between -20~+50°C, RH≦85%
e. The Probe should not be submerged into liquids.
Holding the thermometer too long may cause a higher ambient temperature reading of the probe.
This could make the body temperature measurement lower than usual.
Battery replacement
| When the “Low Battery” icon indicates the battery is low, the battery should be replaced immediately with AAA *2 pcs batteries.
1. Open the battery cover: Use the thumbs to push battery cover out. (See Figure 1)
2. Insert the new AAA *2 pcs batteries. (See Figure 2)
3. Replace the battery cover. (See Figure 3)

NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the THD2Fxy series is used exceeds the applicable RF compliance level above, the THD2Fxy series should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the THD2Fxy series.
Recommended separation distances between portable and mobile RF communications equipment and the THD2Fxy series
The THD2Fxy series is intended for use in an electromagnetic environment (for
home healthcare) in which radiated RF disturbances are controlled. The
customer or the user of the THD2Fxy series can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the THD2Fxy series as recommended
below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in meters (m) can be estimated using the
equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer. NOTE 1 At 80 MHz and 800 MHz, the separation
distance for the higher frequency range applies.

NOTE If necessary to achieve the IMMUNITY TEST LEVEL, the distance
between the transmitting antenna and the ME EQUIPMENT or ME SYSTEM may be
reduced to 1 m. The 1 m test distance is permitted by IEC 61000-4-3.
a) For some services, only the uplink frequencies are included.
b) The carrier shall be modulated using a 50 % duty cycle square wave signal.
c) As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does not represent actual modulation, it would be worst case.
