５.How to replace the battery
Please insert a coin etc. in the groove of the battery lid on the back side and turn it until it
stops in the direction of the arrow.
Hold the back of the case downwards, magazines etc. If you hit lightly on objects of
moderate hardness, the back lid and batteries will come off.
* In order to prevent breakage of the battery fittings, even when the battery does not come
off do not mess with a screwdriver etc. Please remove it by lightly tapping it.
* Please be careful not to touch the metal fittings with the battery removed. It may not
operate properly due to deformation, dirt, etc.

the battery.
* As shown in the picture below, please push in so that the top side of the battery is first
and slide upward from the bottom side.
Never use batteries other than the lithium button battery CR 2032.
Fit the back cover and turn it in the direction of the arrow until it stops.

７.Cautions
★Notes on Radio Law
· Disassembling / remodeling of this product is prohibited. Please disassemble / remodel it.
· Do not remove the label on the back of the case.
★Handling Precautions
· Never use such a way that product malfunction or malfunction directly relates to human
life.
This product is not designed in consideration of applications that require high reliability
which may cause danger to the body at the time of breakdown, such as medical equipment
and transport equipment. Please do not use it directly for the purpose of affecting human life.
· Never use batteries other than the lithium button battery CR2032.
· Do not apply strong shock or soak it in water or other solution as it may cause malfunction.
·Even if the battery is reversely inserted, there is no short circuit of the battery, and there is
no damage to the equipment, but please do check it carefully as it will not work.
· Because this product uses radio waves, communication may become impossible due to the
influence of noise etc. Even if it becomes impossible to communicate, please be careful in
designing the external circuit so that there is no safety problem.
· Depending on the nature of the radio waves, dead points may occur due to the positional
relationship with the receiver, and communication may become impossible even within
communication distance. In this case, if you move the transmitter or receiver about 25 cm,
you may be able to communicate.
· The communication distance may be lowered near motors or other noisy equipment. In this
case, it may be improved by adding measures such as adding a spark killer, strengthening
the shield, taking measures against noise sources, or devising such as keeping the receiver
away from noise sources.

Please do not use this product in a way that its failures and errors may involve human lives.
