Standard radio clock
This clock receives radio waves carrying accurate time information and automatically corrects the displayed time.
When using, place it near a window where it can receive radio waves as easily as possible, and avoid places where radio noise is generated.
When radio waves are not being received, it operates with the accuracy of a quartz watch.
Please note that accurate reception may not be possible in the following locations.
・Inside a building, between buildings, or underground.
・Near high-voltage lines, television towers, or overhead lines of trains.
・Near home appliances and office equipment such as televisions, refrigerators, air conditioners, air purifiers, computers, and fax machines.
・Places where radio interference occurs, such as construction sites, near airports, or places with heavy traffic.
・Inside a vehicle. (Cars, trains, airplanes, etc.)
・Near other sources of radio noise.
・On or near metal furniture such as steel desks.
*Reception may be possible under certain conditions even outside of reception areas.
Low battery warning
Notifies you when the battery is about to run out.
Available in two types: one where the second hand stops at the 12 o'clock position, and one where a low battery mark is displayed on the digital LCD screen.
Sweep second
The second hand moves continuously and smoothly.
Sleep second hand
When the light sensor detects that it is darker than a certain level,
the second hand automatically stops at the 12 o'clock position.
This has the advantage of eliminating noise when receiving radio waves, improving reception sensitivity, and extending battery life.
