4. Measuring the ear temperature: Use the index nger to trigger. Press “Start” button, a long beep will be sounded when
measurement is done.
5. Power Off: Device will automatically shut off if left idle for
more than 1 minute to extend buttery life. Or press “On/
Off/Memory” button for at least 3 seconds to turn the device
off.
6. Fever alarm: the measuring temperature is higher than
37.5°C(99.5°F), the display will ashing and 4 short beeps
will be sounded. The measuring temperature is higher than
42.2°C(108.0°F), the display will show “Hi“and 4 short beep
will be sounded.
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 “Clean and Storage“ section
after each use.

1. To achieve accurate readings, make sure the ear canal is clean.
2. Press the “On/Off/Memory” button. The thermometer is
ready for use after the ear icon is ashing and two beeps are
sounded.
3. 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.
There are total 9 set memories for body measurement. If the
reading of the thermometers is within the normal temperature
range of 34 °C to 42.2 °C (93.2 °F to 108°F ), when the measurement is done, the measurement data is saved into memory.
• Press “On/Off/Memory” button again to see the temperature stored.
The probe is the most delicate part of the thermometer. Use with care when cleaning the lens to
avoid damage.
1. Please use the cotton swab with the Alcohol to
clean the lens (on the inside of the probe).
2. Allow the probe to fully dry for at least 5 minutes.
a. Please check the device if it falls and damages. If you
can’t make sure of it, please send the complete device
to the nearest retailer for recalibration.
b. Keep the unit dry and away from any liquid and direct
sunlight. The probe should not be submerging into
liquids.
• It means measurable.
• When battery icon appears, please replace the battery.

Recommended separation distance between portable and mobile RF communications equipment and the RA500
The RA500 is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the RA500 can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the RA500 as
recommended below, according to the maximum output power of the communications equipment.

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.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reection from structures, objects and people.

Where P is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer and d is the recommended separation distance in metres (m).
Field strengths from xed RF transmitters, as
determined by an electromagnetic site survey,

should be less than the compliance level in
each frequency range.
b
Interference may occur in the vicinity of equip-
ment marked with the following symbol:
NOTE1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2: These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reection from structures, objects and people.
a. Field strengths from xed transmitters, such as base stations for radio (cellular/cord-
less) 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 xed RF transmitters, an electromagnetic site survey should be considered. If the measured eld strength in the location in which the
RA500 series is used exceeds the applicable RF compliance level above, the RA500
series should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating
the RA500 series.
b. Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
