1.Measured guidelines
(1)Before measuring,please check whether the probe film is in good condition ,if not, do not use.
(2)When measuring,in order to measure correctly please make a probe aimed at the eardrum and the ear canal.
(3)The temperature of two ears is usually a slightly different, so as to compare you had better measure the same each time.
(4)Some people even sick, also won't have a fever.If you are unwell,no matter the measurement show,it is advisable to see doctors immediately.
(5)The following circumstance,you shoud measure the same ear three times and take the highest.
A.The baby was born within 90 days.
B.Three years of age with immune disorders
C.Use not skilled in temperature value,lead to deviation(The same ear frontie measured more than three times,which easily cause measurement value to drop.)
(6)Sleeping aside will cause ear temperature rising,had better wait a few minutes or test another.
(7)Earwax too much will affect the accuracy,should clean ear canal.No earcap,can lead to incorrect measurements, and easy to cause the probe film damaged.After each use,please change new earcap, in order to avoid overlapping infection.

2.Operating procedures:
(1)Before use, confirm the mount of clean ear brand.
(2)Turn on the power button,await symbols “READY”
(3)Fixed subjects head, make its face lateral side and ears up
(4)Tighten ears to keep the ear canal straight. Babies under one year of age,pull the ear to the rear. Infant above one year and adults,ears are pull up and rear.
(5)Put probe into ear canal, to ensure eardrum temperature measurement correct.
(6)Click WenJian measurement, after the beep voice is measured.
(7)Remove temperature probe from the ear canal,and temperature display in LCD.
(8)In dark environment, if necessary, press the backlighting button, and then read temperature (only CT-30DX)
(9)When "REDAY" symbol will no longer be executed flashing,you can test next.
(10)After measuring, please change a new earcap. For 60 seconds if no use, it will be turned off automaticly.

3.Memory data read/remove:
(1)Before the shutdown, last measurement will be stored.Maximum memory is 8 groups(M1-M8), M1 is the last ear temperature.
(2)When the symbol“READY” keep stable and no longer flashing, press power button gently ,which can display memory temperature.
(3)Hold power button for 5 seconds, which can remove all memory, and the signs"CLr"will be shown on the LCD.
(4)No memory temperature on LCD,it will display symbol "... °C or... °F".

4.°C and °Fconversion
(1)Make sure ear thermometer shutdown.
(2)Holding "WenJian measurement"button,click the "power button ON/M
(3)°C and ° F can convert themselves.All the memory will convert units.
(4)Release "WenJian measurement"button.

5.Cleaning ,maintenance and storage
(1)Temperature probe is the most important part of the gun, especially the front,which is the most fragile.Before measuring please confirm whether install ear cap,avoiding damage or dirty detector film.
(2)Make sure whether the probe film damaged or dirty before mounting earwear.If you would like to clean the probe film,you can wipe gently with cotton swabs touched a few alcohol or warm water.
(3)Please wipe LCD monitor and shell gently with clean soft cloth.Don't use the solvent,or soak in water or other liquids.
(4)Do not put this product in the too high or too low environment, or under direct sunlight,contact with electrodes or dust pollution of the environment directly.
(5)Please set the product and earwear in dry place, and keep 5  ~ 40 degrees Celsius (41 °F ~ 104 °F) in the environment..
(6)when not use this product,please fit on new earcap and store in boxes.

6.Change batteries
(1)First make sure ear temperature gun closed,then press battery pack release with pen point to open battery cover.
(2)Unsling battery cover and put in ”CR2032” lithium battery. Please confirm the battery anode (+) on the face.
(3)To close the cover until fixed card tenon fastened.Please do not put the old lithium battery into trash, be sure send to nearby battery recycling.
(4)If changing battery result in instrument can not open,it may be because of system in protecting situation.Please lift the battery cover down and wait 30 seconds,or put in battery again and open machine after click poor-light button for 5 seconds.
