 DANGER

To Prevent Serious Accidents

Do not disassemble, repair or modify the unit and/or accessories.

Do not use the unit in any environment that is exposed to 
chemicals and harmful gases. Doing so may cause corrosion 
and/or other danger to the unit. Also, coming in contact with 
hazardous substances may cause bodily harm to the user or 
people nearby.

This product is not water resistant. If water or a foreign object 
enters the case, immediately remove batteries and stop using it.

Do not handle the unit, remove batteries or cables with wet hands.

Do not touch the unit or AC adaptor during thunder and lightning, 
as this may cause electrocution.

This product has been designed for private and/or industrial 
use only. It should not be used in situations where strict safety 
precautions are necessary such as with medical equipment, or in 
systems directly or indirectly connected with human life or well-
being.

Do not drop or expose the unit to a strong impact.

Do not cut or process the cords for the communication cables. 
Also, do not twist, pull on or swing any of the cords.

To prevent damage to the unit from static electricity, remove static 
electricity from your body by touching metal around you (such as 
a door knob and window frame) before touching the unit.

Place and store the unit and accessories out of the reach of 
children.

We are not responsible for any damage, malfunction or trouble, 
whether direct or indirect, caused by the use of our product.

Do not use any battery, sensor, or cable other than those specified 
by ESPEC MIC Corporation.

Do not put anything on top of the cable or the unit. This may 
cause overheating.

Do not disconnect the USB cable during USB communication. 
Doing so may cause adverse effects to the unit and/or PC.

Make sure that sensor and cable plugs are all inserted fully, so as 
not to cause an improper connection. Also, when unplugging the 
cable from the unit, do not pull the cord, but hold the connector to 
disconnect.

If the unit produces heat, emits smoke or a strange smell, or 
makes unusual noise, immediately remove the batteries and stop 
using it. Also, unplug the unit from the PC.

If the unit is not to be used for a long period of time, remove 
batteries. Leaving batteries inside the unit may cause battery 
leakage and malfunction. Install new batteries when starting or re-
starting to use a unit.

 CAUTION

Do not place or store in the following 
areas:

•  Areas exposed to direct sunlight
•  Areas subject to direct flames or heaters, as well as areas in which hot air 

accumulates and creates extremely high temperatures

•  Areas exposed to static electricity
•  Areas exposed to strong magnetic fields
•  Areas exposed to water leakage
•  Areas subject to condensation or wet areas
•  Areas exposed to excessive vibration
•  Areas exposed to excessive smoke, dust or dirt.

 CAUTION

Other Precautions

•  Use the unit in the specified operating environment. Do not use it for any 

purpose other than for which it was designed.

•  Condensation may occur inside the case when a unit is moved from one 

environment to another where there is a great difference in temperature.

•  Do not use the unit in wet areas or places exposed to water such as bathroom.
•  When connecting the unit to your PC, make sure to follow all warnings and 

directions from your computer manufacturer.

•  We shall not guarantee the unit's operation if it has been connected to a 

PC using a USB hub or a USB extension cable.

•  Do not insert any foreign objects into any of the units' jacks.
•  If the unit gets dirty, wipe it with a clean cloth.
•  Make sure to remove dust and dirt from plugs of any cables.
•  Battery terminals may provide insufficient contact due to age or vibration. 

This may lead to data loss.

•  Please note that this document has been written based on the 

presupposition that details about contracts with an Internet provider, 
specific network environments and the set-up of any other necessary 
equipment to enable network connection has already been taken care 
of by the User and that connection has been confirmed as workable. 
ESPEC MIC Corporation shall not be responsible for any damages which a 
contractor, a user or a third party may suffer, whether direct or indirect, due 
to the inability to communicate or use communication devices.

 CAUTION

Notices about Sensors

•  Do not connect any sensor to the unit other than those specified by ESPEC 

MIC Corporation.

•  Make sure to use sensors within the measurement range indicated in the 

specifications for that sensor.

•  Do not connect the sensor to any thermo recorder other than those 

specified by ESPEC MIC Corporation.

•  Do not expose the sensor to a strong impact. This may adversely affect 

measurement accuracy and cause damage or malfunction.

•  When the sensor is not to be used for a long period of time, please store it 

at normal temperature and humidity.

•  The included sensor is not water resistant. If the sensor gets wet, 

immediately remove the sensor from the unit and wipe it with a clean 
cloth as soon as possible. Then allow the sensor to dry in normal room 
temperature before using it again.

•  Do not use the sensor on the human body.

Temperature-Humidity Sensor

•  If extremely severe temperature changes occur, it may result in large errors 

in humidity measurement. Once the sensor's temperature becomes stable, 
the measurements will return to normal.

•  The temperature-humidity sensors will with normal use experience losses 

in precision and sensitivity over time due to degradation. If the sensor is 
being used in an unsuitable environment (smoky or dusty places) it may be 
necessary to change the sensor sooner.

•  When using the sensor in an environment where the humidity is under 30 

%RH, the measurements may sometimes fluctuate. This is not abnormal.

•  Do not expose to condensation, dampness, corrosive gases, or organic 

solvents.
