	• Do not disassemble or modify the battery.
	• Never apply heat or place the battery in the fire.
	• Do not place the battery near heating equipment such as cooking appliances or a heater, inside a car under the blazing sun, or in other high-temperature locations (above 60°C or 140°F). Doing so could cause the battery to rupture.
	• While charging or discharging the battery, do not put any flammable material on the battery or cover the battery with a cloth or other materials.
	• Do not place the positive (+) and negative (-) terminals of the battery on or in contact with any conductive materials, such as metal wires. Do not carry or store the battery together with necklaces, hairpins, or other metal objects. Doing so could result in accidental short-circuiting of the battery.
	• Do not wet or immerse the battery in liquids such as water, seawater, beverages, and seasoning agents.
	• Do not beat the battery with a hammer, and do not step on, throw, or drop it.
	• Do not pierce the battery with a nail or other metal objects.
	• Do not touch the terminals of the battery. Doing so could cause the battery to corrode.
	• The lithium ion battery has a finite lifespan. We recommend that you replace the battery after 300 charge cycles or 3 years from the date of first use, whichever comes first.
	• If you notice any dents or cracks on your battery caused by a strong impact or shock, stop using the battery immediately and replace it with a new one. Using the battery in this condition could lead to abnormal overheating or fire.
	• Use only the specified battery.
	• When charging the battery while in the product, use an AC adapter specified by us.
	• When connecting the battery to an outlet such as a car cigarette lighter outlet, always use the dedicated battery charger.
	• Do not rub your eyes if the liquid from the battery leaks and comes into contact with your eyes. Rinse well with clean water such as tap water, and seek medical attention immediately. Otherwise, it could impair your vision.
	• If charging is not completed even after a specified time elapses, remove the battery from the product or battery charger and stop charging. Then, contact your SATO reseller or technical support.
	• If any abnormality is detected (such as a strange odor, overheating, discoloration, deformation, leakage, etc.), stop using the product immediately and perform the following. Then, contact your SATO reseller or technical support. Using the product in this condition could result in a fire, injuries, or electric shock. ◦ Power off the product. ◦ Unplug the power cord from the outlet. ◦ Remove the battery from the product or battery charger, and place it away from any flammable materials.

　

	• Be sure to charge the battery before its first use or when it has not been used for a long time.
	• Charge the battery in the recommended temperature range from 5°C to 35°C (41°F to 95°F).
	• Store the battery in a location out of reach of young children. Also, do not lick the battery or put it in your mouth.
	• Dirty terminals on the battery could result in an unstable connection, battery exhaustion, or an inability to charge. Clean the terminals of the battery with a dry cloth before use.
	• When storing the battery, avoid storing in the following state. Doing so could result in a degraded battery performance or reduced lifespan. ◦ In a fully charged state (a state immediately following the completion of charging) ◦ In a state with no remaining capacity (the battery is so exhausted that it is even impossible to power on the product) An optimal remaining capacity to store the battery is approximately 40%.
	• When not using the battery, store it in a location with low humidity to prevent the battery from leaking or rusting.
	• When replacing the battery, be sure to install it in the correct orientation. Incorrectly inserting the battery could damage the periphery of the battery insertion slot.
	• If you have an old battery to dispose, to ensure the efficient use of scarce resources, seal the contact with tape or with a similar material, and consult with your reseller or technical support on how to dispose them. Do not place the battery together with other batteries such as dry batteries.
