【Important Notice for International Buyers – Tomoayax Premium Audio Hi-Fi Japan】
■ Voltage Compatibility
This product is designed exclusively for use in Japan (AC 100V, 50/60Hz).
Many regions use 120V or 220–240V.
Using this product without a proper transformer in such voltage environments may result in malfunction, overheating, or serious and irreversible damage.
■ Plug Type
This product uses a Japanese plug (Type A or B).
A plug adapter may be required depending on your region.
■ Transformer Requirement (Very Important)
A transformer is required for safe use.
A plug adapter only changes the plug shape and DOES NOT convert voltage.
Using this product without a transformer may cause serious and irreversible damage.
■ Buyer Responsibility
As this is high-end audio equipment, the buyer is fully responsible for confirming compatibility with their local voltage (100V / 120V / 220–240V) and usage environment before purchase.
■ No Return / No Refund Policy
We do NOT accept returns or refunds for:
・Voltage mismatch (including 120V and 220–240V environments)
・Use without a transformer
・Plug incompatibility
・Damage caused by improper setup or usage
■ Liability
We are not responsible for any damage, malfunction, or performance issues caused by improper use or incorrect voltage conditions.
■ Final Notice
Please ensure full understanding of the above before purchasing.
Use only under the correct voltage environment.
