Before Measurement

Please long press the on key to start the product.
Display history

The history record appears on the screen,indicating that the value is the last measured temperature.

Measurement

Note:
Before measuring temperature, please clean the temperature measuring head with or rubbing alcohol. Rinse it with cool water.

The thermometer supports measuring temperature of multiple body parts.

For the infants under 3 months old, it is recommended to measure rectal temperature.

Please follow the below instructions.

Measuring oral temperature

With your mouth open, put the temperature measuring head under your tongue.
Close your lips gently around the thermometer.
Keep the thermometer under your tongue until the digital thermometer beeps.

Measuring axillary temperature

Put the temperature measuring head securely in your armpit.
Hold your arm down tightly at your side.
Keep the thermometer in your armpit until the digital thermometer beeps.

Measuring rectal temperature

Lubricate the probe tip with a water-soluable jelly for easier insertion; do not use petroleum jelly,as it may cause an inaccurate reading. Gently insert the probe tip no more than 1/2 inch into the rectum.

After Measurement

a 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 device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device.
b Over frequency range 150kHz to 80MHz. For Resp field strength should be less than 1V/m.
Recommended separation distances between portable and mobile RF communication equipment and the device

The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the monitor as recommended below, according to the maximum output power of the communications equipment.
Rated max. output power of transmitter (W)| Separation distance according to frequency of the transmitter (m)
150 kHz – 80 MHz d = 1.2 P| 80 MHz – 800 MHz d = 1.2 P| 800 MHz – 2.5 GHz d __ = 2.3 P

100| 12.00| 12.00| 23.00
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (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.
