TH809 Ear-Type Thermometer

Thank you for purchasing the thermometer. This thermometer is

designed with an advanced infrared and ambient temperature

compensation technology for instantaneous self-diagnosis and

accurate temperature measurements.

Operating Instructions:

1. Gently squeeze the opposite ends of the thermometer to

pull off the probe cap. Do not use force to remove the cap.

2. Always use a new and undamaged probe cover.

Make sure the ear canal is clean.

3. Install Probe Cover

1) Place a new probe cover on the connection ring. (See Figure 1)

NOTE：Make sure to place the “Adhesive Side” of probe cover “Upward.”

2) Align the probe with the center of probe cover. Insert the probe into the probe cover on the connection ring.

(See Figure 2)

3) Push the connection ring until the “Click” sound. This means the probe cover has been installed successfully.

NOTE：The probe cover detector is optional. If the probe cover did not connect firmly, the “ ” icon

will flash on the LCD screen. Please check the setting of the probe cover again.

Proper installation of the probe cover ensures accurate measurements.

Warning：Keep the probe covers and connection ring away from children.

4. Press “ON/MEM” button to power on. The thermometer is ready for use after the ear icon stop flashing and two short

beep sound.

5. Gently pull the ear back to straighten the ear canal and snugly position the

probe into the ear canal, aiming towards the membrane of the eardrum to obtain

an accurate reading. ( Fig.4-1)

6. Measuring the ear temperature：Use the index finger to trigger. Press the “Scan”

button until you hear a long beep. ( Fig.4-2 ).

7. Power off：This device will automatically shut down after 1 minute pending to extend battery life.

NOTE：

a. It is recommended that you measure 3 times with the same ear. If the 3 measurements are different, select the

highest temperature.

b. To avoid the risk of cross contamination, please clean the probe according to “Cleaning and Storage” section after

each use.

c. Clinical repeatability: 0.20°C (＜1 year old), 0.14°C (1~5 years old), 0.14°C (＞5 years old)

Switching between Fahrenheit(°F) and Celsius(°C):

In “Power Off” mode, press and hold the “SCAN” 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.

Memory Function:

If the reading of the thermometer is within normal temperature range between 34

o

C to 42.2

o

C (93.2

o

F to 108.0

o

F),

when the thermometer is off, the last measurement data is saved into memory. Press the “ON/MEM” button

again to see the temperature stored.

Cleaning and Storage:

The probe is the most delicate part of the thermometer.

Use with care when cleaning the lens to avoid damage.

Storage temperature Range: It should be stored at room temperature between -20~+50°C, RH≦85%

Keep the unit dry and away from any liquids and direct sunlight.

The Probe should not submerge into any liquids.

** If device is accidentally used without probe cover, clean the probe as follows:

a. Please use the cotton swab with Alcohol (70% concentration) to clean the lens( on the inside of the probe).

b. Allow the probe to fully dry for at least 1 minute.

NOTE：Please check the device if damaged once it falls. If you can’t make sure of it, please send the

complete device to the nearest retailer for recalibration.

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.

Changing the Battery:

This device is supplied with one lithium cell (CR2032 x 1).

○

1

Open the battery cover: Insert a pointed object into the battery cover pick hole. At the same time, use thumb to remove battery

cover.

(See Figure 1) ○

2

Flip the battery out with a small screw driver (See Figure 2) ○
