【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.
A solar radio-controlled watch with a titanium body that gives it a luxurious feel. - Since titanium is used as the material, the body weighs only about 72g. - The LCD at 6 o'clock has a convenient function that displays the calendar, world time, alarm, timer, etc.-You can adjust the size by yourself using the included special tool. ・Multi-band 6 solar radio clock that supports standard radio waves in Japan, China, America, and Europe. - Equipped with tough solar that allows charging even under familiar lights such as fluorescent lights - Equipped with LED light for peace of mind at night and in dark places - Water resistant to 10 ATM for peace of mind even when around water
■Multi-band 6 Radio wave reception function that receives standard radio waves from 6 stations around the world over a wide range and automatically adjusts the time.The built-in highly sensitive small antenna and unique detection and reception technology make it possible to receive radio waves in the frequency bands (40kHz to 77.5kHz) of Japan (Fukushima station/Kyushu station), China, the United States, the United Kingdom, and Germany.In addition, we have achieved space savings by adopting a crystal-less heterodyne system.
■Tough Solar Casio's unique solar charging system converts not only sunlight but also light such as fluorescent lights into power.By receiving light from the solar panel and generating electricity to charge the built-in secondary battery, it stably operates many functions that require a strong load, such as the time display, alarm, and lights.
