The IV-18 VFD tubes Clock (Energy Pillar) is a fully assembled and calibrated timepiece. It features an eight - digit IV-18 (ΝB-18) VFD tubes display made in the USSR from 1980 - 1990, showing a clear cyan fluorescence that younger generations might not have seen. This clock displays hours, minutes, and seconds, and offers multiple display formats for date and time. It only needs a 5 - volt power supply via the Mini USB cable, and comes with an infrared remote controller for rich functions. With built - in temperature and light sensors, it automatically adjusts the brightness according to the environment. Its aluminium alloy shell with anodizing process and gold - plated PCB make it a great vintage clock for collection. Specifications include options for 12 or 24 - hour format, displaying Chinese lunar date, GPS adjustment, GMT time zone functions, temperature display in °C or °F, two alarm clocks, and many other useful features. It also has an extremely accurate RTC module and a built - in backup lithium battery. The package includes the clock, an IR remote controller, and a Mini USB cable, along with a user manual.
Using the IV - 18 VFD Tube Energy Pillar Time Clock is easy. First, connect it to a power source using the Mini USB cable. The clock will start up and you can use the infrared remote controller to set the time, date, and other functions. You can choose between 12 - hour or 24 - hour format, and different date display formats according to your preference. For the alarm clocks, set the time and turn them on or off as needed. The temperature display can be set to show in Celsius or Fahrenheit. To adjust the brightness, you can either choose one of the 8 levels manually or let the clock adjust it automatically based on the light in the room. When you move the clock, the auto - switch upright and upside - down mode will ensure the display is always the right way up. As for maintenance, keep the clock in a dry and clean place. If it gets dirty, use a soft, dry cloth to gently wipe it. The built - in backup lithium battery will keep the time for over 3 years without power, but if you plan to store the clock for a long time, it's a good idea to disconnect it from the power source.
