Warning English PLEASE READ THIS MANUAL BEFORE ANY ATTEMPT TO USE THIS PRODUCT IS MADE. PRECAUTIONS The ear thermometer must be inserted correctly to obtain correct temperature measurement. Be sure to consult a physician if you feel that your health is in poor condition. DO NOT judge your health only on the presence or absence of a fever. 1. Make sure that the probe lens is always clean. KEEP PROBE LENS CLEAN GOOD NOT GOOD 2. Very carefully and gently insert the probe into the ear. 3.
- Eng 3 - English Caution 1. The body temperature measured in the ear may differ from measurements taken under the armpits, in the mouth, or in the rectum. Therefore, comparing them will not be of value. Take temperature readings periodically to determine the normal ear temperature measurement with this instrument, then use that reading as the basis for comparison with any measurement taken when you suspect a fever. 2. Do NOT use this thermometer for measurements other than as specified.
English About Ear Thermometers All objects radiate heat. To measure body temperature, this ear thermometer uses an infrared sensor incorporated in its probe to detect the heat radiated from the eardrum and the area around it. In general the ear canal (external auditory canal) of an infant is relatively straight. As we grow older, it takes on some curvature, as shown in Fig. 2. It is important to point the probe lens of the ear thermometer toward the eardrum and its periphery inside the ear.
FUNCTIONS This thermometer has the following functions for care of users. • Ear Temperature: for human temperature. • Time and calendar: for memory. • Room Temperature: for monitoring the ambient temperature for a baby or patient. • Material surface temperature (NOT for body temperature): for temperature of a baby's milk, etc. • Stop watch: for taking a patient's pulse. • Fever alarm: an alarm when a user's temperature is more than 37.5°C, indicative of a fever.
English EAR TEMPERATURE 1. Make sure that the probe lens is clean. 2. Press ON/MEM button and after the all indicators show up on the display (Fig.6), the ready message with icon displays, accompanied by two short beeps (Fig.7). Fig.6 Fig.7 3. Gently pull the ear back to straighten the ear canal (Fig.3) and gently position the probe into the ear canal, aiming towards the membrane of the eardrum to obtain an accurate reading. 4.
MATERIAL SURFACE TEMPERATURE / STOP WATCH 1. Make sure that the probe lens is clean. 2. Press ON/MEM button to enter the EAR TEMPERATURE mode. 3. MATERIAL SURFACE TEMPERATURE: Press and hold the ON/MEM button and then press the SCAN button once to leave the EAR EMPERATURE mode and enter the MATERIAL SURFACE TEMPERATURE scan icon (Fig.10). mode with (Material surface temperature mark) Fig.10 3.
English 4. STOP WATCH: (Stop watch mark) Fig.11 4.1 This mode counts from 0.01sec to 3 minutes. 4.2 To start and stop the stopwatch, press the SCAN button. To reset the counter, press the ON/MEM button. Press and hold the ON/MEM button and then press the SCAN button once to leave STOP WATCH mode and return to the EAR TEMPERATURE mode. FEVER ALARM If the thermometer detects a temperature over 37.
If this unit is left unattended for about 1 minute, it will automatically power down from the current mode and enter the stand-by mode, showing room temperature, time, and date. The display alternates between time and date in a pattern that repeats every minute as follows: time 11 sec / date 4 sec / time 11 sec / date 4 sec / time 30 sec. BATTERY REPLACEMENT 1. Replace the battery when the display behaves as follows: The stand-by mode shows NOTHING on the display except the time and date.
English Caution 1. Remove and then reinstall the battery if the Er message is displayed, if the display is abnormal, or if nothing is displayed when the ON/MEM button is pressed. 2. To protect the environment, dispose of the used battery according to local regulations. 3. Remove the battery if the ear thermometer will not be used for a long time. 4. Keep the battery away from children. CARE AND CLEANING, STORAGE The probe is the most delicate part of the thermometer.
DESCRIPTION OF DISPLAY MARK Meaning Measurement before device stabilization. The device showing a rapid ambient temperature change. The ambient temperature is not within 10 to 40°C (50 to 104°F). The system is not functioning properly. (1) Ear temperature mode: Temperature taken is higher than + 42.2°C (108°F). (2) Material surface temperature mode: Temperature taken is higher than + 80°C (176°F). (1) Ear temperature mode: Temperature taken is lower than + 34°C (93.2°F).
English Questions and Answers Q1: Why is temperature measured in the ear different from measurements taken under the armpit, in the mouth, or in the rectum? A1: Temperatures of different parts of body may vary. Compare the measurement in question with a normal temperature previously taken in the same ear. Q2: The temperature differs each time I take a measurement.
SPECIFICATIONS For Ear temperature mode 34.0~42.2°C (93.2~108°F) For Material surface temperature mode -22~80°C (-7.6~176°F) Accuracy: For Ear temperature mode ±0.2°C (0.4°F) for temperatures 35.5~42.0°C (95.9~107.6°F). ±0.3°C (0.5°F) for other ranges. For Material surface temperature mode ±0.3°C (0.5°F) for temperatures 22~42.2°C (-7.6~108°F) for other ranges. ±4% or ±2°C (4°F), whichever is greater.
