BESTMED DET-306 Infrared Forehead Thermometer Owner’s Manual

Introduction

The DET-306 infrared forehead thermometer is specifically designed for safe use on the forehead. The Infrared Forehead Thermometer is a device capable of measuring people’s body temperature by detecting the intensity of infrared light emitted from the forehead. It converts the measured heat into a temperature reading displayed on the LCD. Infrared Thermometer is intended for the intermittent measurement of human body temperature by people of all ages.
When properly used, it will quickly assess your temperature in an accurate manner.

Please read all instructions carefully and thoroughly before using this product.

Warning:

There is no gender or age limitation for using infrared forehead thermometer. This thermometer can be reused by many people.
Use of this Forehead thermometer is not intended as a substitute for consultation with your physician.
Do not allow children to take their temperatures unsupervised, some parts are small enough to be swallowed.
Never immerse this device in water or other liquids(not waterproof).
Do not modify this equipment without authorization of manufacturer.
Do not expose the thermometer to temperature extremes (below -25°C/-13°F or over 55°C/131°F) nor excessive humidity (>95%RH).

Basic Functions

Real Time Clock| The real time clock will be recorded with the memory function and help you to recognize each measurement result.
— Please see the Real time clock setting section to learn how to setup the time in the first use.
---|---
Forehead Mode| The thermometer has been designed for practical 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 see the Illustration For Use section to learn how to
measure the body temperature.
Object Mode| The object mode shows the actual, unadjusted surface
temperatures, which is different from the body temperature. It can help you to monitor if the object temperature is suitable for the baby or patient, for example the baby’s milk.
— Please see the Illustration For Use section to learn how to measure the object temperature.
Beep Alarm| If thermometer detects a body temperature 37.8t(100.0°F)
under forehead mode, there will be a long beep sound followed by three short beep sound to warn the user.
Memory Mode| There are each 10 sets memories for forehead and object measurements. Each memory also records the measurement date/time/mode icon.
°C/ °F Switch| Please see the Selecting A Temperature Scale section to learn how to change between Celsius and Fahrenheit.

Forehead Thermometer Advantages

Infrared Forehead Thermometer measures core body temperature, which is the temperature of a body’s vital organs. (See Figure 0 This thermometer is designed to measure the temperature of the skin surface over the temporal artery, a major artery of the head. The temporal artery is connected to the heart via the carotid artery, directly leading from the aorta, the main trunk of the arterial system. It offers constant blood flow. Therefore, body temperature changes are reflected sooner in the forehead than they are in other parts of the body such as oral, rectal and underarm. Vital Organs

Temperature Taking Hints

To ensure that the reading always reflects the body temperature accurately, you need to take account of the following factors which may affect an accurate reading.

It is important to know each individual’s normal temperature when they are well. This is the only way to accurately diagnose a fever. To determine normal temperature, take multiple readings when healthy. Re-measure with a standard digital thermometer for confirmation.
Users must be inside for 30 minutes before taking a measurement. Note: Users and the thermometer should be in the same ambient temperature for at least 10 minutes before taking a reading.
Users should not drink, eat, or be physically active such as bathing, showering, shampooing and hair drying before/while taking the measurement. Remove hat and hair and wait 10 minutes before taking a reading.
Oils or cosmetics on the forehead may give a lower temperature reading than the actual one. Remove dirt from the forehead before taking a measurement. Wait at least 10 minutes after washing the forehead area before taking a reading.
Holding a hand on the forehead for any length of time will affect the temperature reading.
Do not take temperature over scar tissue, open sores or abrasions.
Do not use the thermometer on a perspiring or sweating forehead, as this may affect the reading.
Don’t take a measurement while or immediately after nursing a baby.
Do not use this thermometer outdoors.
Do not take temperatures with this thermometer near places that are very hot, such as fireplaces and stoves.
The probe window of the thermometer is the most delicate part of the device. Do not touch the probe window. The accuracy of the reading may be affected if the probe window is damaged or dirty.
If the thermometer is stored in a significantly different environment than testing location, place it in the testing location for approximately 30 minutes prior to use.
It is not intended for use in the oxygen rich environment or presence of flammable anesthetic mixture with air, oxygen or nitrous oxide.

Illustration For Use

To measure forehead temperature:

Press the BUTTON, The display is activated to show all segments. After self-checking Figure 2 appears on the display screen with beeps, so you can start a new measurement.
Aim the thermometer at the center of the forehead with a distance of 2 to 3 cm(See figure 3) and then press the START BUTTON.
Note: Do not remove the thermometer from the forehead before hearing the final beep. A waiting period of 3 seconds between testing is recommended to ensure complete accuracy.
Read the temperature on the display.
Press the BUTTON to turn off.

How to change the forehead mode and object mode:

You can press BUTTON to switch the mode between Forehead mode and Object mode. IP.

To measure object temperature:

Press the ****BUTTON to turn on the thermometer, you can take the object temperature after hearing two beep sounds.(see figure 4)
Aim the thermometer at the center of the object you want to measure with a distance of Ito 2 cm.
Press the START BUTTON and then read the temperature on the display.
Press the ****BUTTON to turn off.

After measurement:

Power off: Device will automatically shut off if left idle for more than 1 minute to extend battery life.
